摘　　要：本文介绍了砚北煤矿地应力测量的方法、过程和结果。通过现场实测 ,获得了矿区 2个水平 4个测点的地应力大小和方向 ,并通过回归分析得出了矿区的地应力场分布规律。This paper mainly introduces the method,the procedure and the result of the in situ stress measurement of Yanbei coal mine. Through the field measurement, the in situ stress's value and orientation of the 4 stations in 2 levels were gotten. And by regression analysis, the in situ stress field's regularities of distributions of the mining area was also gotten. The measurement result has great significance to the coal mine's producing and building.
