摘　　要：采用数值模拟与概率积分相结合的方法,对唐山矿铁二采区T2291工作面开采进行了模拟,将覆岩裂缝按层间和法向两个方向分别研究,综合确定该工作面回采后覆岩裂缝分布范围。与数字式全景钻孔摄像实测的对比结果表明,模拟与实测结果相吻合,可以采用该方法确定覆岩裂缝的分布范围。Applying combined method of numerical simulation and probability integral,fissures distribution range in overlying strata over T2291 mining face of 2nd mining area of Tangshan Colliery was simulated from horizontal and vertical direction.Compared with the result from borehole camera,the simulation result was fit for observation result.The method could be used to obtain fissure range of overlying strata.
