摘　　要：本文采用岩土力学数值计算有限差分方法,建立了"11.6"矿难塌陷区采场的三维数学模型,反演了该采区的开采历史和围岩破坏、围岩应力分布、地表沉陷、监测点位移变化等情况,从力学角度阐述本次事故发生发展的过程,对地下采场的安全稳定性给出了客观的评价。为事故处理责任的认定和避免同类事故的发生提出了参考性意见。Based on the finite difference method in rock-geotechnical mechanics, 3D numerical simulation model of gypsum mine in collapse field was set up to judge the stability of underground mining area. Mining history, damage of wall rock, stress distribution, settlement of ground and displacement of monitor points were studied within the numerical model. The results can give a reference for the responsibility confirmation, and make it possible to avoid some similar accidents.
