Justification of the Value of Well Drilling During Explosion of Leads

Abstract

The article considers the influence of the strength of rocks, the type of explosive height, the diameter and length of the charge in the drilling of wells on the quality of crushing rocks. It has been established that about 50% or more of the length of the drilled well is used irrationally, and only 50% is used for its intended purpose for destroying the explosive charge in order to destroy the massif by explosion. To determine the effect of the distance between the charges on the value of the resistance overcome along the sole, industrial experiments were carried out at the quarries of the NMMC and AGMK.
