Essay

The object of the thesis is efficient rise of explosive substances cylindrical charges action when destroying rock with simultaneous decrease of quarry atmosphere pollution by noxious gases. Firing-pins displacing of vertical axes of a charge increases the effect of many times loading that is the oretically and experimentally proved. Rational correlation of hole diameter and firing-pin when destructed rock average diameter having the latest value is determined. Rational mixture of gas neutralizing composition used in cylindrical charge decreasing noxious gases concentration in the atmosphere of an open pit is substantiated.
