浅埋薄基岩矿井工作面超前支承压力分布规律研究

摘要

通过现场安设不同深度的钻孔应力计对某浅埋深薄基岩煤矿的工作面超前内部应力分布进行了监测。基于采集的应力数据，本文对工作面内部不同深度处超前应力环境进行了分析，给出了该矿工作面煤壁超前应力受采动影响的范围，并给出了煤壁附近顶板发生侧向断裂的范围。该研究结果对矿山灾害的预防有指导作用。%The paper monitored pilot roof support pressure distribution law of coal mining face in shallowly buried and thin bedrock coal mine through field installation of different depth of borehole stress meter .Based on the collecting data, different depths pilot roof support pressure distribution law was analyzed , the advance pressure of the wall affected by mining area and the roof fracture range near the coal pillar were given.The re-sult in this study is very useful for mine disaster prevention.
