METHOD FOR BLAST UNLOADING OF ROCKS ROUND WORKING

摘要

Method for blast unloading of rocks round working makes it possible, due to rational placement of unloading blast holes and substantiated sequence of blasting those in ceiling and walls of working, to increase effectiveness of blast unloading of rocks round working, with simultaneous blast backing of fixation space, to form thrust of fixation in surrounding rocks to increase bearing ability of those, to decrease labor consumption and to simplify implementation of works.
