摘要:
摘要:梧桐庄矿182309工作面是孤岛仰采工作面,仰采角度大,矿压显现明显,煤壁极易片帮。针对以上问题,以梧桐庄矿182309工作面为工程背景,采用FLAC3D和UDEC数值模拟软件模拟分析了工作面周围的应力分布情况和煤壁片帮情况。在此基础上,工作面采用了超前预注浆加固技术措施,有效地控制了煤壁片帮现象。

Abstract:
Abstract:WuTongZhuang No.182309 mining face was an isolated up-dip mining face with the angle of the mining face wide , the strata pressure violent and the phenomenons of rib fall of coal wall frequent. In view of these problems, taking WuTongZhuang No.182309 mining face as project background,the condition of the stress near the mining face and the rib of coal wall were analyzed by use of numerical simulation software FLAC3D and UDEC. Based on the above study results, the mining face adopted a scheme of pre- grouting which effectively controled the phenomenon of the rib fall of coal wall.
Key words: Key words: isolated mining face, overhand mining, numerical simulation, rib fall of coal wall
