摘要
通过对大采高工作面超前支承压力的观测并进行总结分析 ,掌握了大采高工作面在开采过程中巷道围岩应力的活动规律 ,确定了今后大采高工作面和普通综采工作面巷道掘进的支护方式及回采生产时的超前支护形式 ;
Through monitoring the rock pressure of the working face and analyzing the original data, work out the rules of the rock movement around the road, then make decisions on how to support the road during excavating and extracting, to prevent the roof of road from caving while excavating in the road and extracting in the face.
