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。
對長溝峪煤礦的急傾斜煤層進行瞭數值模擬,併對推採不同距離時的垂直應力雲圖進行分析,得齣危險區域為工作麵的上下耑頭,與實際開採情況基本吻閤,說明數值模擬方法可為急傾斜煤層安全開採和遲擊地壓的防治工作提供參攷。

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.
