神东矿区近距离煤层群开采矿压规律探究

Study on Pressure Regularity with Close-distance Coal Seam Group in Shendong Mining Area

以石圪台矿为例,研究了综采工作面矿压显现规律,得到了工作面来压判据、来压特征和进出上覆煤柱时的压力变化规律,为类似综采工作面顶板控制提供可靠的技术支持,促进安全生产。

The strata behavior of mechanized longwall mining face in shigetai Mine was taken as an example,which drew the pressure criterion and characteristics of working face as well as the pressure changing when passing through the overlying pillar,which provided reliable technical support of roof control for similar mechanized mining face and promoted the productive safety.
