分析了1262(1)工作面煤层赋存特征,建立了工作面的三维地质模型;以煤层顶板岩石的力学试验结果为参数,利用FLAC3D软件对开采引起的煤层覆岩运移进行了数值模拟;分析了开采过程中煤层覆岩的位移和应力分布规律,讨论了工作面煤层顶板的破坏形式及变形特征。
The seam deposit features of No.1262(1 { DK) coal mining face were analyzed and the 3D geological model of the coal mining face was established.With the rock mechanics experiment results of the roof above the seam as the parameters,the FLAC3D software was applied to numerical simulation on the rock movement and displacement above seam occurred by the coal mining operation.The paper analyzed the displacement and stress distribution law of the strata above seam during the coal mining process and had a discussion on the failure mode and deformation features of the roof above seam of the coal mining face.
