摘　　要：针对覆岩离层这一特殊的接触问题提出了新的接触算法,并采用大规模并行计算方法实现了对离层进行真正三维的力学模拟,从而得到覆岩离层空间几何形态参数。以济宁二号煤矿西部十一采区为研究实例,验证了算法的适用性及有效性。Based on the specialty of separation layer, this paper proposes a new contact algorithm with the adoption of massive parallel computation for the study of separation of overburden layers in coal mine production. We have done the real 3D mechanic simulation and get the potential location, shape and volume for separation of overburden layers. Meanwhile, the study takes the area of No. 2 coal mine of Jining as an example, which proves the applicability and validity of this new algorithm.
