综采工作面超前支承压力观测的应用

the Application and Observation of Tre-suptorping in the Fully-mechanized Face

通过对回采工作面超前支承压力的观测,掌握回采工作面巷道围岩应力的活动规律并进行总结分析,确定今后回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;全面防止掘进巷道和回采巷道顶板的漏顶事故。

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.
