Essay

Thesis deals with the current scientific and technical task of improving the parameters of drilling and blasting technology of driving the vertical shafts for a combined scheme of penetration to increase the stability of rock outcrops and the strength of monolithic concrete lining. It is made the complex of field and analytical studies which have revealed pattеrns of change in the random factors that determine the stability of the rock outcrops and strength of reinforced concrete lining in the shafts. It is proposed a new scheme of breaking rocks with benching shape face, the advantage of which is to reduce the destruction of the wall rocks in the bottom of the stope and, for the specific conditions of penetration of the shaft, its reasonable effective parameters are substantiated. The passports of blasting the ledge forms of the shaft face are designed and "Recommendations to reduce the magnitude of the devastation of shaft contour, strumming and volume of the concrete" are introduced during the drive of air supply shaft №3 of Mine office "Pokrovs'ke".
