摘要
针对深部煤炭工作面支护效果差、工作面变形严重的问题,以某煤矿为研究对象在分析其地质水文、顶底板情况的基础上,分析普通锚杆支护方案下所存在的问题及原因,并将恒阻大变形锚杆支护技术应用于该煤矿中。通过对恒大变形锚杆支护效果进行监测,得出恒大变形锚杆支护具有优于普通锚杆支护的控制效果的结论。
In view of the problems of poor supporting effect and serious deformation of deep coal face, based on the analysis of geological hydrology and roof and floor condition of a coal mine, the problems and causes of common bolt support scheme are analyzed, and the constant resistance large deformation bolt is applied to the coal mine, and the effect of evergrande deformation bolt support is monitored.
