| 摘 要： | 以龙口市洼东煤矿蒂带开采的地质采矿条件为依据，建立了岩体蠕变的粘弹性力学模型，确立了其蠕变参数，利用ANSYS的三维立体模型对同一工作面务带开采不同采留宽度条件下的地表下沉和力学效应进行了数值模拟计算，分析了煤柱及其围岩的稳定性和安全性，提出了软岩矿井建筑物下条带开采的合理采留宽度，从而论证了软岩矿井建筑物下特殊开采的可行性，为决策者进行采矿活动提供了科学的依据。

| Abstract: | In this paper, based on the geological and mining conditions of strip mining in Wadong Mine of Longkou City, the viscous-elastic mechanical model of rock mass is established and its creep parameters are chosen. The surface subsidence and mechanical effect under different conditions of various coal pillar widths in strip mining in the same working face is numerically simulated and calculated by means of ANSYS 3D model. The stability and safety of pillars and its surrounding rocks are analyzed, and the rational coal pillar widths of strip mining under buildings in soft rock mines are brought forward, thereby the feasibility of the special mining under buildings in soft rock mines is demonstrated. |
