孤岛工作面支护技术研究与应用

Research and Application of Support Technology for Isolated Island Face

孤岛工作面地质条件复杂,矿压显现剧烈,围岩破坏严重,巷道支护困难,对煤矿安全回采具有重大影响。143上16综采工作面是已三面回采的典型"孤岛"工作面,工作面地应力大,巷道破坏严重。研究143上16综采工作面支护机理,对于在相似条件下的巷道支护具有借鉴作用。

The working conditions of the island face are complex, the rock pressure is severe, the surrounding rock is damaged seriously, and the roadway support is difficult. It has a great influence on the safe mining of the coal mine.143 upper 16 fully mechanized face is a typical ＂isolated island＂ working face which has been extracted on three sides. The stress in the working face is large and the damage of the roadway is serious. The support mechanism of the 143 upper 16 fully mechanized face is studied, which can be used as a reference for the roadway support under similar conditions.
