【摘要】 为解决采动影响下的巷道围岩应力集中、变形大等支护难题,以华润煤业205运输顺槽为例,采用FLAC3D数值模拟软件,分别对工作面顺槽受采动影响前和受采动影响时围岩屈服破坏情况、垂直应力分布、垂直和水平位移特征进行分析,得出205运输顺槽受采动影响时的最优支护方式和参数,并且成功用于工程实践。更多还原

【Abstract】 To solve stress concentration and severe deformation of surrounding rocks under the influence of mining,taking No.205 transporting crosshead as an example,the FLAC3D numerical simulation software was used to analyze the yield failure of surrounding rocks,vertical stress distribution,and vertical and horizontal displacement before and after the mining.The optimal support method and parameters in the mining has been successfully used in engineering practice.更多还原
