【摘要】 使用FLAC3D有限差分软件对安庆铜矿5#柱采场空区进行稳定性分析。结果与回采爆破临近结束时实际发生的矿岩变形破坏状况较为吻合,岩体变形破坏主要集中在空区上部对应的凿岩硐室顶板及大理岩薄板处。分析结果对制定合理有效的支护措施、保证空区稳定提供了参考。更多还原

【Abstract】 The stability of 5# stope goaf in Anqing Copper Mine is analyzed by using FLAC3D soft ware of limited difference.The result is consonant with the actual situation that the rock distortion and destroy take place in the ceiling of drill chambers above the stope goaf as well as the lamella.The analysis result offers a reference merit in order to constitute rational and available timbering measure,thereby pledges stope goaf’s stability.更多还原
