| 摘 要： | 为确定五阳煤矿"孤岛"综放工作面合理护巷煤柱宽度,控制回采巷道变形破坏,以7603工作面为工程背景,采用三维有限差分软件FLAC3D,对不同护巷煤柱宽度条件下的回采巷道围岩应力分布和塑性区发育特征进行了模拟分析,结果表明:该工作面合理的护巷煤柱宽度为22.5m。

| Abstract: | In order to confirm the reasonable width of protective coal pillar in isolated fully-mechanized working face of Wuyang coal mine for the purpose of controlling the deformation and failure of mining roadway,the stress distribution of surrounding rock and the developing characteristics of plastic zone in No.7603 working face were simulated by using FLAC3D numerical simulation software under the conditions of different coal pillar widths.The results showed that the reasonable width of the protective coal pillar should be 22.5 m for this working face. |
