摘　　要：为确定东沟兰州湾煤矿开采后地表塌陷范围及深度,采用数值实验的方法,对4号煤层东西翼采区进行了大范围的开采过程模拟,获得了地表沉陷的三维变化趋势,阐明了现有塌陷区的产生过程,同时与理论计算结果进行了对比,验证了数值实验的准确性,提高了预测工作的精准度,可为同类工作提供方法借鉴。In order to determine the range and depth of surface subsidence after mining in Donggou Lanzhouwan Coal Mine,a large-scale mining process was simulated in the east-west mining area of No.4 coal seam by using numerical experiments,the three-dimensional change trend of surface subsidence was obtained,and the generation process of the existing subsidence area was clarified.At the same time,it was compared with the theoretical calculation results,which verified the accuracy of the numerical experiment and improved the accuracy of the prediction work,which can provide a method for similar work.
