陆东煤矿C_(16-2)煤层矿压显现规律实测分析

通过对陆东煤矿C_(16-2)煤层216-204W回采工作面进行矿压观测研究,分析了工作面基本顶初次来压和周期来压步距及强度、巷道超前支承压力及围岩变形,为矿区内及周边的其他采煤工作面开采提供了借鉴。

Based on the observation and study of the mining pressure of 216-204W mining face in C_(16-2) coal seam of Ludong Coal Mine,the initial and periodic pressure step distance and strength of the basic roof of the working face,the leading abutment pressure of the roadway and the deformation of surrounding rock are analyzed.it provides a reference for the mining of other coal mining faces in and around the mining area.
