摘要
采用ＦＬＡＣ数值模拟软件，研究了七种围岩结构型式巷道在不同跨采应力环境中的松动圈发育规律，得出不同围岩结构组成型式对巷道围岩松动圈的最终发育形态和发育程度具有重要影响的结论，通过井下工业性试验的验证。
Using numerical simulation software FLAC,this paper studies the developing laws of broken rings of 7 kinds of rock structures in different stress fields round the roadways under working face. Then,a main conclusion has been found that rock structures are important to the ultimate shape of broken ring round the roadways have structural features.
