| 摘 要： | 为了实现西曲矿近距离下位煤层工作面顺槽在上部遗留煤柱及采空区交叉区域的有效支护,以29205工作面顺槽为例,对该区域顶板稳定性进行了分析,并据此给出了相应的支护方案。支护实践表明,29205工作面顺槽在此交叉区域变形量不足设计尺寸的7%,支护效果较好,能够满足支护要求。

| Abstract: | In order to realize the effective support of the coal pillars left in the upper part and the intersection area of goaf in the working face of Xiqu Coal Mine,taking the 29205 working face as an example,the roof stability in this area is analyzed,and the corresponding support scheme is given.The support practice shows that the deformation of 29205 working face in this cross area is less than 7%of the design size,and the support effect is good,which can meet the support requirements. |
