急倾斜煤层的冲击地压危险区域划分研究

摘要

In the paper,there is a analysis of numerical simulation on the steeply inclined coal seam in the Changgouyu coal mine,there are anlysises on the cloud picture of vertical stress and plastic strain under the different pushed distance,the dangerous areas are up and down the working face,results obtained by the numerical simulation basically consistent with the actual situation.So the method of numerical simulation provides the reference for safely mining of the steeply inclined coal seam and prevention of rockburst.%对长沟峪煤矿的急倾斜煤层进行了数值模拟,并对推采不同距离时的垂直应力云图进行分析,得出危险区域为工作面的上下端头,与实际开采情况基本吻合,说明数值模拟方法可为急倾斜煤层安全开采和冲击地压的防治工作提供参考。
