对北京昊华能源股份责任公司的长沟峪煤矿的急倾斜煤层进行三维数值模拟，利用ANSYS有限元软件单元“处死”的功能真实模拟4槽工作面的开挖过程，对沿巷道走向和沿煤层走向推采不同距离时的塑性应变云图和应力云图进行分析，得出数值模拟结果与现场实际开采情况基本吻合，说明ANSYS有限元数值模拟方法可为冲击地压的防治工作和煤矿的安全开采提供参考。
對北京昊華能源股份責任公司的長溝峪煤礦的急傾斜煤層進行三維數值模擬，利用ANSYS有限元軟件單元“處死”的功能真實模擬4槽工作麵的開挖過程，對沿巷道走嚮和沿煤層走嚮推採不同距離時的塑性應變雲圖和應力雲圖進行分析，得齣數值模擬結果與現場實際開採情況基本吻閤，說明ANSYS有限元數值模擬方法可為遲擊地壓的防治工作和煤礦的安全開採提供參攷。

In the paper,there is a analysis of three dimensional numerical simulation on the steeply inclined coal seam in the Beijing Haohua en-ergy shares the responsibility of the company’s Changgouyu coal mine,based on the function of element is“killed”of ANSYS finite element a-nalysis software to really simulate mining process of 4 slot mining face,there are anlysises on the cloud picture of vertical stress and plastic strain under the different pushed distance along the roadway and the seam of pushing. Results obtained by the numerical simulation basically consistent with the actual situation. So the method of numerical simulation provides the reference for the prevention of rockburst and safely mining of the coal.
