IZZAMIR NABIHAN BINA. MAJID

Muhamad Izzamir Nabihan Bin A.Majid dilahirkan pada 8 Oktober 1992 diHospital Besar Kuala Lumpur. Anak keduadaripada lima orang adik beradik iniadalah seorang anak yang sentiasamenanam impian untuk menjadi anaksulung lelaki yang bekerjaya bagi mem-bantu keluarganya. Hal ini disebabkanbapanya, En. A. Majid Bin Abd Gafforyang kini berumur 55 tahun akan bersaradaripada berkhidmat sebagai anggotapolis tidak lama lagi. Hasrat ini telahdikhabarkan berulang kali kepada ibunya,Suria Binti Omar dan adik-beradiknyayang lain. Beliau menjadi harapan keluar-ga kerana beliau merupakan anak lelakisulung dan bakal menamatkan pengajiandi dalam jurusan Ijazah Sarjana MudaKejuruteraan Sumber Mineral di UniversitiSains Malaysia.

Sejak kecil lagi, beliau berhajat untukmelanjutkan pelajarannya di UniversitiSains Malaysia. Hal ini kerana USM adalahtempat yang akan dilihatnya terlebihdahulu setelah melalui Jambatan PulauPinang setiap kali keluarganya pulang kekampung ayahnya di Gelugor. Perkara inidiberitahu oleh ibu bapanya sendiri.Menjadi seorang mahasiswa USM meru-pakan kebanggaannya dan juga keluarga.Cita-citanya untuk menjadi seorangJurutera Pemprosesan Mineral di RahmanHydraulic Tin Sdn. Bhd. iaitu tempat beli-au menjalani latihan industri selama 10minggu (semasa di tahun tiga) juga ser-ing diceritakan kepada sahabat-sahabat-nya di universiti. Minatnya begitu men-dalam di dalam aktiviti perlombonganbermula sejak tahun pertama berada diuniversiti. Buku ensiklopedia kecil menge-nai batuan dan mineral yang disimpandalam beg beliau sentiasa dibawanya kemana sahaja bagi dijadikan rujukan.

Beliau dikenali sebagai seorang yangmudah didekati dan disenangi oleh orangramai terutamanya pensyarah-pensyarahdan rakan-rakan di universiti. Sikapnyayang ramah dan terbuka juga membu-atkan semua selesa untuk bergaul den-gannya. Di kampus, beliau sangat aktif didalam aktiviti kokurikulum, badan persat-uan dan juga khidmat masyarakat. Sukanyang sangat digemarinya ialah ragbi.Beliau menyertai banyak perlawanan diperingkat universiti dan juga negeri.Sukan ini menjadi sukan kegemarannyasetelah beliau memasuki universiti.Dorongan jurulatih dan rakan-rakanmembuatkan beliau bersemangat untukmenceburi sukan ini. Beliau telah dilantiksebagai pengerusi bagi kelab ragbi di uni-versiti. Kejohanan Ragbi 10 Sebelah USMkali ke 10 merupakan jasa terbesar beliaudalam usaha mempromosikan sukanragbi di universiti dan negara.

Kebolehannya dalam pengurusan sesuatu acara atau program membuatkan kejo-hanan tersebut berjaya dilaksana denganjayanya.

Di kampus, beliau merupakan ketuaexco desasiswa yang didiaminya iaituDesasiswa Jaya. Sifat kepimpinan yangdimiliki membuatkan beliau ditawarkanjawatan tersebut. Pada awal tahun 2015,beliau pernah melibatkan diri dalam misibantuan banjir di Temerloh, Pahang. Halini disebabkan sikapnya suka membantuorang di dalam kesusahan. Perkara inidapat dilihat di dalam aktiviti harian dikampus. Beliau sedia memberi khidmatbantuan kepada rakan tanpa mengirawaktu dan sebarang alasan. Sikapnya initurut dikhabarkan oleh ibunya ketikamana beliau berada di rumah. Oleh sebabitu, beliau mendapat perhatian ramaidalam kalangan pelajar di universiti.

Sesungguhnya Allah s.w.t. lebihmenyayangi beliau setelah terlibat didalam kemalangan ketika mengikutilawatan akademik ke Acheh, Indonesiapada 11 Mac 2015 yang lalu. Kehilanganbeliau amat dirasai oleh keluarga, handaitaulan dan universiti. Semoga roh beliaudicucuri rahmat dan mendapat pengam-punan daripada Allah s.w.t.

There is a way to learn “INNOVA-TION” in a systematic approach. Theapproach is called TRIZ or Theory ofInventive Problem Solving. TRIZ is aRussian methodology discovered about66 years ago but has remained a well-kept secret. This open-secret has finallyreached you through the MyTRIZ Level1+ Workshop (© MYTRIZ).

This workshop was organize by Schoolof Materials & Mineral ResourcesEngineering (SMMRE) in collaborationwith the Malaysia TRIZ InnovationAssociation (MYTRIZ) and Multimedia &Development Corporation (MDeC).

The aim of this workshop is to bridgethe gap in understanding complex prob-lem solving from the academia and indus-tries perspectives. Complex problemsolving is a multifaceted skill that isrequired among 21st Century Graduates.This attribute is also an essential outcomefor accreditation of engineering pro-grammes. Therefore, learning andexploring on a systematic inventive prob-lem solving is important in meaningfullypreparing and developing our future engi-neers.

This workshop was attended by 49 stu-dents including undergraduate and postgraduate students; participation not onlycomes from SMMRE but also School ofElectrical and Electronic Engineering. ACertified Trainer for TRIZ Level 1, Dr.Zuratul Ain Abdul Hamid has conductedand delivered TRIZ Level 1 syllabusthroughout the two days workshop. Thecertification was endorsed and certifiedby MDeC and MYTRIZ and recognized

worldwide as the workshop followed the TRIZ International syllabus. The work-shop is hopeful to initiate the creativityand provide a systematic inventive prob-lem solving that can be used by the stu-dents in any problem or research works.

The success of this workshop will notbe realized without the help of organizingcommittee lead by Ms. Nor Ezza Sofiah,3rd Year Polymer Engineering student.Their enthusiasm and hard works haveresulted in the smooth and success of theworkshop. It is important SMMRE supportmore similar workshop to be organized toenhance and value add our students inproblem solving skill, communication skilland also build up their confident levelwhenever facing any problem in theirstudies.

6.0 Mine Tours

Students and staff at the mine conductguided tours for the general publicthroughout the year. Tours generally lastone hour, but can be tailored to accom-modate some special requests. More thanone-half mile of underground workingsrepresenting over 100 years of mine development are covered on the tour.

Lighted displays showing drilling, blasting,and mucking equipment are displayed on the mine tour and items of discussion include mining practice, mining econom-ics, and the role of the mining industry inmodern society. The mine is usually rela-tively dry and a constant 54 degreesFahrenheit, year-round. CSM provideshard hats for tour members, but guestsare asked to wear warm clothing and stur-dy walking shoes. Sorry, but the mine isnot wheelchair accessible.

7.0 Summary

Edgar Mine is the experimental mine ofColorado School of Mines. The experimen-tal mine can be a good example of how mining engineering education being deliv-ered in U.S.A. It can be a very good les-son to be learned of becoming an engi-neer that proof the real life experiencesare the best mentor the students can getduring their study period.

AbstractNi embedded ZnO nanorods were synthe-sized by two step solution precipitationmethod followed by reduction in H2

atmosphere at 500oC for 2 hours. TheXRD analysis shows that the as-synthe-sized particles were ZnO that well crystal-lized in hexagonal wurtzite structure.There is no Ni (or NiO) diffraction peakscould be found in the XRD analysis.TheSEM image confirmed that the morpholo-gy of ZnO nanorods did not change withNi loading on its surface. The EDX analy-sis shows the present of Ni beside Zn andO elements. The photocatalytic activity inremoval of RhB dye by Ni embedded ZnOnanorods was greatly enhanced whenusing a smaller UV excitation source. Thephotodegradation efficiency using UVlight with wavelength of 254 nm almostcompletely removed RhB, i.e. 98% within75 min as compared to 58% when usingUV light with wavelength of 352 nm. It isworth mentioning that the rate constantof using 254 nm UV light is 0.048 min-1,which is four times larger than using 352nm UV light.

1.0 IntroductionSemiconductor photocatalysts have beenattracting research focus recently becauseof its great potential as remedy to solveenvironmental problems [1]. These semi-conductor photocatalysts could be used toremove organic pollutants by degradingthem into less harmful byproducts such aswater and carbon dioxide under sunlight[2]. In addition, their other applicationsas environmental remedy are to inactivatemicrobial [3]and remove heavy metals[4]. Amongst the semiconductors, wide bandgap TiO2 (3.2 eV) is the most studied pho-

tocatalyst as it has high photochemicalefficiency and stability [5-7].A suitablealternative to TiO2 is ZnO [8] as it pos-sesses a similar bandgap (3.3 eV), lowcost and non-toxic nature. Studies haveshown that ZnO demonstrated a betterphotocatalytic efficiency than TiO2 inremoval of 2-phenylphenol [9], Reactiveblue [10], Rhodamine 6G [11], Acid Red14 [12] and Acid Red 18 [13] in aqueoussolution.Many attempts have been made toimprove photocatalytic efficiency of ZnOphotocatalyst in degradation of organiccompounds. One of the approaches is tomodify the surface of ZnO by coupling ofanother metal oxide semiconductor toachieve a higher light adsorption capacityby shifting the absorbance to visible lightregion [14, 15]. Another way of improvingthe photodegradation efficiency is bymeans of restricting the electron-holerecombination rate of ZnO. This could beachieved by embedding metals such asAu [16] and Ag [17] onto the surface ZnOparticles.In this work, Ni embedded ZnO nanorodswere prepared by two-step solution pre-cipitation. Since ZnO is capable of absorb-ing irradiation in UV wavelength attrib-uted to its wide band gap, the effect of UVexcitation sources on the photodegrada-tion efficiency of Ni embedded ZnOnanorods in removal of RhB dye was stud-ied.

2.0 ExperimentalStacked ZnO nanorods were synthesizedby solution precipitation method asdescribed in our previous paper [18].Subsequently, the Ni embedded ZnOnanorods were synthesized by immersingthe ZnO nanorods into 0.03 M of Ni(NO3)2aqueous solution. The mixture was stirredat room temperature for 24 hours to allowthe deposition of nickel particles onto thesurface of ZnO nanorods. The white pre-cipitate was filtered and dried in the ovenfor 12 hours at 120oC. The product wascalcined at 500oC for 1 hour and reducedunder hydrogen atmosphere at 500oC for2 hours.The photocatalytic study on the Niembedded ZnO nanorods in removal ofRhodamine (RhB) dye was conductedusing different UV excitation sources (254nm and 352 nm). The photocatalyticactivity of Ni embedded ZnO nanorodswas achieved by irradiating mixture of 20mg ZnO Ni embedded ZnO nanorods and30 ml RhB (1x10-5 M) by UV light. Then,photodegradation of RhB solution wasdetermined by monitoring the decay of its553 characteristic absorption peak usingUV-VIS Spectrophotometer (Cary 5).

3.0 Results and discussion3.1 Structural and optical properties of Niembedded ZnO nanorodsXRD patterns of as-synthesized particlesare represented in Figure 1. The diffrac-

tion peaks could be indexed to wurtziteZnO crystal structure (JCPDS No. 01-079-2205) with lattice constant of a = 3.250nm and c = 5.207 nm, regardless ZnOparticles or Ni embedded ZnO particles.The diffraction peaks at 31.74o, 34.40º,36.26º, 47.52º, 56.54º, 62.84º, 66.26º,67.92º and 68.98º are corresponded to(100), (002), (101), (102), (110), (103),(200), (112) and (201) crystal planes ofhexagonal ZnO. Their strong and sharpfeatures suggest that the samples werewell crystalline. No impurity peaks wereobserved for both types of particles. Thisresult indicates that only a small amountof Ni particles was deposited onto the sur-face of ZnO nanorods, which was belowthe XRD detection limit.

Figure 2 (a) shows the field emissionscanning electron microscopy (FESEM)image of as-synthesized ZnO nanorods. Itcould be clearly seen that the nanorodshave hexagonal tips. As shown in Figure 2(b), the morphology of Ni embedded ZnOnanorods did not change with Ni loadingon its surface. However, as shown inFigure 2 (c), small particles could befound on the surface of ZnO nanorods.These particles were homogeneously dis-tributed on the surface of ZnO nanorods.The EDX elemental analysis was per-formed on the Ni embedded ZnOnanorods. As shown in Figure 3, theanalysis indicates that Ni embedded ZnOnanorods compose of Zn, O and Ni ele-ments.

Figure 4(a) shows the TEM image of Niembedded ZnO nanorods. Very fine Niparticles with size below 9 nm weredeposited uniformly onto the surface ofZnO nanorods. The HRTEM image of Niembedded ZnO nanorod is shown inFigure 4 (b). The d spacing of 0.26 nmand 0.20 nm are corresponded to the(002) planes in the ZnO crystal lattice and(111) plane planes of face-centered cubic(fcc) Ni[19].

The optical band gap of ZnOnanorods and Ni embedded ZnOnanorods were investigated using UV-Visabsorption spectra [20]. The band gapenergy was calculated by extrapolation ofthe linear portion of the plot with respectto hv at α = 0 as shown in Figure 5. Theoptical band gap for both ZnO nanorodsand Ni embedded ZnO nanorods is 3.09eV, indicating that the small amount of Niloading was not sufficient to cause redshift of the absorption edge of Ni embed-ded ZnO nanorods [21, 22].

3.2 Photocatalytic StudyThe effectiveness of Ni embedded ZnOnanorods to degrade RhB solution usingUV light with different wavelengths wasstudied. Figure 6 shows the degradationof RhB solution over a period of timeusing Ni embedded ZnO nanorods as pho-tocatalyst. The RhB solution decolorizedgradually when exposed to UV radiationfor 0 min, 15 min, 30 min, 45 min, 60 minand 75 min. Figure 6 (a) shows theabsorption spectra of photocatalyticallydegraded RhB aqueous solutions in thepresence of Ni embedded ZnO nanorodsunder 352 nm of UV light. Theabsorbance peak of RhB significantlydecreased to 0.5354 a.u. after 45 min ofUV irritation, then continued down to0.4030 a.u. upon prolonging the irritationtime to 75 min. Figure 6 (b) shows theabsorption spectra of photocatalyticallydegraded RhB aqueous solutions in thepresence of Ni embedded ZnO nanorodsunder 254 nm of UV light. Theabsorbance peak of RhB significantlydecreased to 0.1512 a.u. after 45 min ofUV irritation, and then down to 0.0200

a.u. upon prolonging the irritation time to75 min. It could be clearly observed thatthe degradation of RhB solution wasfaster when using UV light with 254 nmthan UV light with 352 nm wavelength.As shown in Figure 7 (a), Ni embeddedZnO nanorods achieved a higher pho-todegradation efficiency when using UVlight with wavelength of 254 nm (98%) ascompared to 352 nm (58%) after 75 minirradiation. By plotting the data as ln(Co/C) of the time-dependent normalizeddye concentrations (which is the ratiobetween the initial concentration and theconcentration upon reaction) in Figure 7(b), linear plots are obtained. This indi-cates that the decomposition of RhB fol-lowed first order kinetic regardless theoptical excitation wavelength. The rateconstants, which determined from theslopes of Figure 7 (b), is increased almostfour times, i.e. from 0.012 to 0.048min─1 when the UV wavelength waschanged from 352 nm to 254 nm. Thisresult indicates that a smaller wavelengthof excitation source (254 nm) suppliedmore energetic photons which could pro-

duce more electron hole pairs that wereneeded to form free radicals for moreeffective degradation of RhB dyes.

4.0 ConclusionsNi embedded ZnO nanorods were suc-cessfully synthesized via two step solutionprecipitation, followed by reduction in H2atmosphere at 500oC for 2 hours. The Niparticles (<9 nm) were deposited uni-formly onto the surface of ZnO nanorods,without changing the morphology andhexagonal wurtzite crystal structure ofZnO. The EDX analysis shows the presentof Ni beside Zn and O elements. The pho-tocatalytic activity in removal of RhB dyeby Ni embedded ZnO nanorods wasgreatly enhanced when using a smallerUV excitation source. It is noted that thephotodegradation efficiency after 75 minwas improved from 58% to 98%, and rate

constant was increased from 0.012 min−1

to 0.048 min−1 by changing UV excitationsource from 352 nm to 254 nm. The moreenergetic photons from the 254 nm UVsource generated more charge carriersthat were needed for the formation offree radicals. As a result, the RhB dyedegraded faster when 254 nm excitationsource was used in this study.

AbstractA traditional pour point depres-

sant (PPD) of acrylate polymer is in solidform at room temperature. The costingfor preheating is a prerequisite to be con-sidered for its utilization in a crude oilindustry. The PPD was improvised as anemulsion system in order to increase itsflow ability. Evaluation of the emulsionsystem has been elucidated and its pourpoint depressant performance has alsobeen studied. The emulsified productcould flow as low as -20oC. The viscosityof emulsified product is much lower thantraditional PPD, which is about 16 CP. Theparticle size of the sample becomesincreased by freeze thawed activities, butdoes not affect the stability of the emul-sion. The zeta potential is about -43 MVshowing that the emulsion is in the stablerange. The pour point performance ofemulsified product is better compared totraditional PPD. The increasing trends ofperformance by increasing the injectionshowing that the polymer content is themost influenced factor that increasedpour point performance of emulsifiedproduct.Keywords: Emulsified PPD, emulsion eval-uation, PPD performance

1.0 IntroductionA traditional pour point depressant ofacrylate polymer (Trade name: PD90) hashigher polymer-solvent interaction andlow glass transition temperature. It willcause the PD90 to solidify at room tem-perature. To resolve this problem, emul-sion technique was used to create emulsi-fied PD90 to form fine droplets in a mix-ture. The emulsion has two differentphases in which the water-based will forma continuous phase to act as a carrier forthe oil polymer-based hence give a betterflow ability to PD90[1]. However, theknowledge on the emulsion state of theacrylate polymer after being emulsified isstill scarce in the literature. Hence, thepresent study aims to investigate emul-

sion behavior such as freezing point, vis-cosity at room temperature, particle sizeand zeta potential of the emulsified prod-ucts and to evaluate its performance aspour point depressants towards syntheticcrude oil/paraffin wax solution after beingemulsified.

2.0 MethodologyPD90, emulsifier (MWV) and Solvesso 150were supplied by ACME Chemicals(Malaysia) Sdn. Bhd. Xylene and ethyleneglycol were purchased from Merck Sdn.Bhd. PD90 consist of 40 to 60 wt. % ofacrylic polymer in xylene. Emulsified PD90was prepared by mixing all chemical at 50oC and stirred at 500 rpm for 1 hour. Themixture was sonicated at 70 Hz until themixture reach 60oC. The thermal proper-ties were determined by using MettlerToledo DSC1-Differential ScanningCalorimetry (DSC), United States system

apparatus with nitrogen as purge gas.Starting from -60oC, each sample below10 mg was first heated until reaching 120oC , held isothermally and then cooled to-60oC at a pre-defined rate of 5oC/minute. Viscosity of PD90 after emulsi-fied were measured by using Brookfieldviscometer. Viscometer was loaded withsamples and sheared by using spindle setno 04. Particle size and zeta potentialwere measured on a Malvern InstrumentsNano ZS Zetasizer, using a flow throughcell with a Malvern Instruments MPT-2Multi Purpose Titrator. Freeze thawed testwas conducted by freezing the samples inchiller at temperature -10oC for 20 hours.Then the samples were taken out andheated in water bath at 50oC for about 4hours. Samples are then being cooleddown at ambient temperature beforeobservations had been made. The cycleshas been made until week 4 which equal-ly to 4 cycles. The pour point performancetesting has been made according toASTM-D97 method. The method involvesperiodically tilting a tube containing sam-ple of crude oil at decreasing tempera-tures, to find the temperature wherethere is no movement of the crude.

3.0 Results and Discussion

Flow ability of emulsified PD90Solvent based PD90 has a low meltingpoint of around 45oC which will make itsolidify at room temperature. To utilizethis chemical additive in crude oil’s well,preheating is required to make sure thatthis material is pump able. The introduc-tion of an emulsion system to PD90 wouldproduce a flow able material at room tem-perature so that the preheating costwould be discarded. Figure 1 shows theDSC curve for the solvent based PD90and emulsified PD90. From the figure, itshows that the emulsified PD90 has themelting point of -20oC while solvent basedPD90 is 45oC. This is due to the emulsionstate that allowing the water-based to actas a medium without forming any directinteraction between the polymer. In thesystem, polymer would be encapsulating

by emulsifier to present as small dropletor particle inside the water-based.Unlikely, the polymer in solvent basedPD90 had directly coiled with the solventso that solution tends to solidified at lowtemperature. Viscosity of emulsified PD90The viscosity is the most importantparameter that would be considered forachieving a good flowability of pour pointdepressant. After being emulsified, theemulsion viscosity is only 16 cP at roomtemperature as shown in Table 1. Theresulted value of emulsified product issufficiently low and suitable for applica-tion as the traditional PPD with the rangeof <300 cP [2]. Low viscosity wouldreduce the cost for pumping during appli-

cation. The viscosity of the solvent basedPD90 was not able to be measured as itsolidify at room temperature.

Particle size and zeta potential ofemulsified PD90Particle size is the most important param-eter that indicates the stability of anemulsion [3]. As an emulsion system isbeing introduced for this PD90, it has atendency to break and the solutionbecomes separated at elevated tempera-ture. In considering that factor, freezethaw test has been conducted for emulsi-fied product. Figure 2 below shows thetrend of particle size for the sample afterbeing freeze-thawed for 4 cycles within20 days. The particle size increases by thenumber of freeze-thaw cycles applied tothe samples. However, this trend wouldnot affect the stability of the emulsion asthere is no separation observed duringthe test as shown in Figure 3 below. Inorder to confirm the stability of the emul-sion, zeta potential of emulsified PD90 isalso determined. The zeta potential valueof emulsified PD90 is about -43 mV. Forsuch a situation the colloid will be morestable, the further away it is formulatedfrom the isoelectric point. The value is inthe range (±40 to ±60 mV) for good sta-bility of emulsion [4]. The electrostaticrepulsion of the particles become maincontributor that will lead to a stable dis-persion. The stable emulsion would make

sure that it would be able to use in anextreme condition as well as could

improve storage capability.

Applied test, ASTM D97A pour point depressant performance testwas conducted to study the emulsifiedPD90 response or performance towardssynthetic crude oil after being emulsified.From Figure 3, emulsified PD90 showingexcellent pour point reduction as com-pared to solvent based PD90 conductedat 50oC. This is due to ability of emulsifiedPD90 to flow at low temperature as com-pared to solvent based PD90. The flowability of emulsified PD90 provides higherenergy so that it could efficiently propa-gate in order to inhibit the crystallizationgrowth of paraffin wax. Furthermore,micron size of polymer producing fromemulsified product could provide highersurface area so that the interactionbetween polymer and paraffin wax wouldbe higher. Increase of additive dosagecould also increase the pour point reduc-tion of paraffin wax. This is attributed tohigh active content of the polymer whichefficiently inhibits the formation of crys-tallization growth of wax.

4.0 ConclusionEmulsion behavior such as freezing point,viscosity at room temperature, particlesize and zeta potential of the emulsifiedproducts has been studied. EmulsifiedPD90 could flow at room temperaturewhile solvent based PD90 become solidi-fied. Emulsified PD90 could flow at coldertemperature as the freezing point of thesolvent is around -20oC. It would ensurethat emulsified PD90 could be stored in acold environment as well. The viscosity ofemulsified PD90 at room temperaturewas much lower than traditional PPDresults of an ease handling and storage.The particle size trends have been evalu-ated after the emulsified PD90 undergofreeze thawed testing. The trend showsthe increment but do not affect the stabil-ity of emulsion. The zeta potential datahad confirmed the stability of the emul-sion. The good stability of emulsifiedPD90 would allow them to store at anycondition without any separation. Theperformance as pour point depressants

towards synthetic crude oil after beingemulsified has been successfully evaluat-ed. The performance as pour pointdepressant for emulsified PD90 is betterthan solvent based PD90. The perform-ance also increased as the active contentof polymer increased.

1.0 IntroductionThe mountains above Idaho Springs andthe nearby communities of Black Hawk,Central City and Georgetown show theabandoned mine openings and remnantsof a romantic past: the "Rush to theRockies" and feverish mining for silverand gold. The Edgar mine, the ColoradoSchool of Mines (CSM) ExperimentalMine, is a contemporary to that era. Inthe 1870s, it produced high-grade silver,gold, lead and copper. Today, as anunderground laboratory for future engi-neers, it produces valuable experience forthose who are being trained to find,develop, and process the world's naturalresources.The Edgar mine is located inIdaho Springs, approximately 40 mileswest of Denver, Colorado, U.S.A. It can bereached by Interstate 70 or U.S. 6.

The CSM Mining Engineering Departmentis proud of the Edgar Experimental Mineand the purposes it serves: educational

tours for the public and school groups;cooperation with industry, state, and fed-eral organizations in research; and train-ing of the manpower needed to maintainthe nation's leadership in the field of min-eral engineering. Industry is highly sup-portive of the research and educationalprograms at the mine. In fact, most of theequipment used at the mine is donatedby individual businesses and corpora-tions.

2.0 An Underground ClassroomThe Edgar Experimental Mine (Figure 1)provides CSM students in MiningEngineering and other disciplines with aunique environment for research andpractical training in mining techniquesand systems. In this underground labora-tory, CSM students gain hands-on experi-ence in underground mine surveying,geological mapping, rock fragmentationand blasting practice, mine ventilationfield studies, rock mechanics instrumen-tation practice, underground mine unitoperations, and mine safety. Through acourse in the practical use of miningequipment, students can apply classroomexercises to real situations in a realisticmining environment.

The course runs the full cycle of under-ground mining operations, and includeshands-on experience with drilling, blast-ing, and mucking (loading blasted rock)using both rail mounted and rubber-tiredmining equipment. By the completion ofthe course students have earned safetycredentials in underground mining froman MSHA certified mine safety traininginstructor.Although the Edgar Experimental Mine ismanaged and operated by the MiningEngineering Department, students from

other disciplines have the opportunity tointeract with the mine through projects inboth EPICS and Senior Design. Examplesin recent years includes: Documentationand Design of a Mine Water DistributionNetwork for the Edgar Experimental Mine,Design of a Power Distribution Network ofthe Edgar Experimental Mine Army Adit,Modifications to the Surface DrainageNetwork for the Edgar Experimental Mine,Design of a Compressor Installation forthe Edgar Experimental Mine Army Adit.

3.0 ResearchResearch is carried out on a continuingbasis at the Edgar Experimental Mine.Numerous academic, government, andindustry groups, including the CSMMining Engineering Department, theNational Institute for Occupational Safetyand Health (NIOSH), the U.S. Army,MainNet, Vital Alert and others participatein cooperative research ventures at thefacility. Studies include tunnel detection,blasting, rock mechanics, communica-tions and development of new miningequipment and methods.

4.0 Industrial Outreach ProgramsThe CSM Mining Engineering Departmentconducts a comprehensive industrial out-reach program, including mine rescuetraining, for the mining industry.Collaborators include the ColoradoDivision of Minerals and Geology (CDMG)and the Western Mining Resource Center(WMRC).

5.0 Edgar Mine Rescue TrainingProgram

The Mining Engineering Department –Mine Safety and Health Program (Figure2) operates a full function mine rescuetraining facility for use by the miningindustry. Mine rescue training can bedeveloped and tailored to the specificneeds of any mining operation. Specialtraining can be conducted for mine oper-ators to address the individual needs ofvirtually any mine. The rescue trainingincludes:

• Incident Command for Mine/Underground emergencies

• Comprehensive Mine and Underground Search and Rescue

• Computer rescue simulation training

• General Heavy Lifting and Rescue using air bags

• Confined space rescue training• Rope rescue training• Mine firefighting

Courses can be conducted either on-siteat the Edgar Mine or at mine sites any-where within the United States. TheMining Engineering Department (MSHP)collaborates with the Colorado Division ofReclamation, Mining and Safety to con-duct Mine Emergency ResponseDevelopment exercises, mine rescue con-tests, and other training.
