METHOD FOR PENETRATION OF A GEOLOGICAL ABNORMALITY WITH DISTURBED LAYER STRUCTURE

摘要

Disclosed is a method for penetration of a geological distortion with disturbed layer structure. Determination of character and structure of disturbed zone is carried out through drilling survey holes at critical predictive section to expected distortion. Evaluation of the level of outburst danger one carries out through interval measurements of initial rate of gas liberation in holes. One realizes penetration of geological distortion by breakage face, at that breakage of rock in the zone of displacement of the layer one carries out by explosive method or by a combine with remote control. Location of geological distortion is adjusted by survey holes. At that determination of the level of outburst danger of distortion is carried out through comparison of dimensions of the zone of unloading of the layer in distortion and out of the boundaries of the critical predictive area, and distortion is considered to be dangerous if unloading zone near distortion becomes smaller.
