摘要
Abstract
In view of the situation where some parts of the 9-208 working face in Dianping Coal Mine will excavate below the edge of the coal pillars in the industrial square and nearby villages,in order to ensure the protection coal pillars not affected by mining and excavation damage,the movement angle values obtained from the mobile observation stations established on the 9-200 surface and the 3-3032 roadway of the mine are used to predict the range of mining influence of the 9-208 working face.The probability integral method is used to predict the degree of surface influence after stoping of the 9-208 working face in advance,and the safety stoping of the 9-208 working face is evaluated.To maximize the safe and efficient extraction of valuable coal resources,minimize the influence of underground mining on the surface,provide scientific and reliable technical basis,and resolve the increasingly scarce coal resource dilemma in mines.关键词
