摘要

应用渗流与应力耦合分析软件EPSCA3D和三维有限元软件ANSYS，分别研究了木架山和东桐峪金矿采空场处理前、后的顶板力学特性。结果表明，渗流将会引起采空场处理后的岩体移动量减小；顶板应力的变化取决于渗透性和流向；渗透性较流向对顶板应力重分布的影响更大；若渗流流向近似水平，则上部采空区顶板的拉应力增大，压应力减小；若渗流流向近似135°，则上部采空区顶板的拉应力、压应力都减小。渗透性和流向受赋存的隔水层的控制。

Abstract

Roof mechanical characteristic before and after disposing abandoned stope is studied respectively by rock mass stress

displacement and seepage computation

together with their coupling analysis （EPSCA3D） and 3-D FEM (ANSYS) in Mujia Hill and Dongtongyu Gold Mine. The results show that after disposing abandoned stope

surface subsidence and rock movement will decrease due to seepage. The stress change on roof lies on rock-mass permeability and seepage direction. The influence on stress redistribution resulting from penetrability is greater than that from the seepage direction. If the seepage direction is almost horizontal

the tensile stress increases

and the press stress decreases on roof of upper part of abandoned stope. If the seepage direction is nearly 1350

the tensile stress and the press stress both decrease in roof of upper part of abandoned stope. The rock-mass permeability and seepage direction are controlled by existing water-resisting layer.
