使用有限元数值模拟方法对某地下矿岩层及地表移动随采矿过程的变化规律和发展趋势进行了研究 ,对影响岩层及地表移动的主要因素进行了定量比较、分析 ,指出该矿浅部由民采留下的未充填采空区是引起地表沉降和地面建筑物变形、破坏的主要原因 ,为采取相应控制措施提供了依据
Using the finite element numerical simulation method, the variation regularities and development trends of the underground rock strata and surface movement with the mining process are studied. The main factors affecting the rock strata and the surface movement are quantitatively compared and analyzed. The left un-filled gob area is the main reason that causes the surface subsidence and the deformation and destruction of the ground buildings, which provides the basis for taking corresponding control measures
