Abstract: The article

shows

that application of the parallel-close charges cause

distance substantial growth between separate bunches of holes, in concrete

mountain-geological conditions. The method of detonation of the parallel-close

charges is effective only at certain diameters of holes. Dependences of optimum

distance between holes from their effective diameter, density and speed of a

detonation of industrial explosives, durabilities of rocks to crush, relations of

acoustics rigidity industrial explosives and blown up rocks are received.

Key words:

high benches, hole, blasting, parallel-close charges, distance between

holes, rock strength, rock.
