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. - [1]. - - - [2]. S y S=S 1 - S 2 , S 1 abcd; S
