大埋深强动压下综放工作面风、机两巷变形综合治理研究与应用

Study and Application on Comprehensive Treatment of Deformation of Air and Machine Two Roadway in Working Face under Large Buried Depth and Strong Dynamic Pressure

随着矿井开采深度的增加,工作面巷道受到的地应力水平也越来越高,巷道的稳定性控制尤为重要,枣泉煤矿130203工作面属于典型的大埋深工作面,巷道回采过程中压力显现剧烈、巷道围岩变形严重,深部高应力软岩巷道的维护问题越来越突出,研究深部高应力软岩巷道变形破坏特征、地应力对巷道围岩破坏及巷道稳定性控制技术有着重要的意义。

With the increase of mining depth,mine working face roadways by in-situ stress level is becoming more and more high,the stability of the roadway control is particularly important.Zaoquan coal mine 130203 working face is a typical working face with large buried depth,and the pressure appears severe and the surrounding rock of the roadways is seriously deformed during the mining process,the maintenance of deep high-stress soft rock roadway is becoming more and more important.It is very important to study the deformation and failure characteristics of deep high-stress soft rock roadway.
