近距离煤层开采的矿压显现

Pressure appearance of mining in close range coal seam

对近距离煤层开采进行矿压显现规律研究,能够在一定程度上避免煤层工作层中应力变化所带来的影响,从而形成稳定的关键层。本文在对某煤矿进行研究的过程中,通过对近距离煤层开采工作面的矿压显现特征进行分析,从而总结出该煤矿工作面当中矿压显现的规律,从而保证工作面的压力分布均匀。

The study of the law of mining pressure in coal seam mining can avoid the influence of stress change in the coal seam to a certain extent,thus forming a stable key layer.In the study of a coal mine,through the analysis of the characteristics of the surface pressure of the close seam mining working face,the law of the mine pressure appearance in the coal face is summed up,so that the pressure distribution of the working face is uniform.
