摘　　要：针对8301工作面特殊的地质开采条件,采用概率积分法及典型曲线法对8301工作面开采引起的地表沉陷规律进行合理预测,研究得出:概率积分法预测地表沉陷时,煤层开采为有限开采对下山边界半无限开采的各值与煤层开采为无限开采时相应的值相近;曲线法预测地表沉陷时,走向主断面半盆地移动变形值均小于倾向主断面下山半盆地移动变形相应值。Based on the special geological conditions of the 8301 working face,using probability integral method,typical curve method to reasonable prediction the surface subsidence caused by 8301 working face mining. Through compared principle and results of two calculation methods shows that the value of semi infinite mining is close to unlimited mining when the coal seam mining is limited with the probability integral method to predict the surface subsidence, moreover, the displacement deformation of the main cross section is smaller than the corresponding values of the trend main section in the lower half of the basin with curve method to predict surface subsidence.
