| 摘 要： | 巷道顶板岩层裂隙水对岩石具有软化、泥化和膨胀变形作用,影响巷道围岩的稳定性.本文采用快速拉格朗日元程序计算分析了岩层裂隙水软化岩石和降低锚杆/锚索锚固力对巷道稳定性的影响.研究得出对砂质泥岩顶板在未受采动影响,且含水率小于1%时裂隙水对围岩稳定性影响不大.图5,表5,参7.

| Abstract: | The crevice roadway. In this paper, water of roof rock will soften, degrade and dilate the rock mass and, affect the stability of a Fast Lagrangian Analysis of Continua code is used to analyze the affection of roof crevice water to the roadway stability and cable anchorage force.Four simulation schemes were conducted. The result shows that the effect is limited when the roadway is not affected by mining dynamic load. 5figs., 5tabs.,7refs. |
