Abstract

A method for mine working bolting includes drilling of bore holes in working, installation and fixation of anchor bolts in the holes. Material and diameter of anchor bolt, distance between neighboring anchor bolts, angle of inclination of anchor bolt to surface of rock exposure are chosen in such way that ratio of reduced elasticity modulus of reinforced rock structure to elasticity modulus of bolted rocks is within from 1 to 1.25 inclusively.
