The efficiency of the blast hole with a

square cross-section

Drill and blast is one of the major processes in mining in the open way.

Currently almost all plosives well at quarry drill cylindrical in shape.

The studies reviewed allow you to see alternative method of conducting drilling and blasting operations.

Research in the field of drilling and blasting, laboratory tests

on the explosion of sand-cement blocks

The distribution of the fractions by weight depending on the shape of the cross section of the hole when blasting sand-cement blocks

Test resultOptimal granulometric composition of the exploded block was observed when using wells with a square cross-section. A small yield of larger fractions indicates the best crushing.

The modeling of the explosion in the mountain range by static loading of the borehole walls with square and round cross-

section

The modeling of the explosion of the round wells with a diameter of 216 mm with a grid of 5x6 m

The modeling of the explosion of the square holes of size 191 mm with a grid 5,5x6 m

The use of wells with a square cross-section allows

To increase the volume of blasted rock mass by 10%.

To increase the yield of rock mass per one meter of the well 10%.

To increase the size of the well grid by 10%.

To reduce the consumption of explosives in blasting operations at 10%.

To reduce the amount of drilling by 10%.

The economic effect from the use of a blast hole with a non-circular

cross-section

On the basis of the research project suggest that the use of wells with non-circular cross-section allows you to: To increase the size of the well grid by

10%. To reduce the consumption of explosives

in blasting operations at 10%. To reduce the amount of drilling by 10%.
