摘要
为进一步研究龙顶山煤矿15号煤层回采工作面回采前后的围岩应力分布情况,以15206工作面为研究背景,采用FLAC3D模拟软件对工作面头尾顺槽和工作面回采期间的围岩应力情况进行模拟分析,结果表明:位于采空区较远一侧巷道所受竖直应力场较大,在应力场作用下,引起工作面回采煤层中部应力相对较大,很容易出现煤层垮落、片帮等应力显现现象。
In order to further study the stress distribution of the surrounding rock before and after the mining of the 15th coal seam in Longdingshan Coal Mine,with the 15206 working face as the research background,FLAC3D simulation software was used to simulate and analyze the stress distribution of the surrounding rock in the head and tail grooves of the working face and during the mining period.The results showed that the vertical stress field of the roadway located on the far side of the goaf was relatively large,and under the action of the stress field,there were relatively high stress in the middle of the coal seam during mining,it is easy to experience stress manifestations such as coal seam collapse and spalling.
