摘要
采用数值计算软件ANSYS ,对矩形煤巷的围岩松动圈进行了数值计算 ,得出矩形煤巷围岩松动圈的形成、发展机理及松动圈的形状 .结果表明 ,矩形煤巷由于断面形状和围岩组成结构的关系 ,其松动圈的形成、发展以及最终形状均与一般巷道明显不同 .
The numerical simulation software of ANSYS is adopted to model the broken rock zones around rectangular shape coal roadways. The development mechanism and the shape of the broken rock zone around rectangular shape coal roadway are worked out. The results indicate that the broken rock zones around rectangular shape coal roadways are clearly different from that around the arch shaped roadways because of the difference in the cross sections and the rock types.
