| 摘 要： | 针对某矿综放面松软、破碎煤层大断面开切眼条件,采用相似模拟试验的方法,比较分析了两种支护方式的支护效果,确定了桁架锚索联合支护的技术方案,并采用数值模拟方法,优化了支护参数.工业试验表明:该支护技术可有效控制松软煤层大断面开切眼围岩变形,为类似条件下的大断面煤巷安全支护提供参考.

| Abstract: | According to the conditions of soft and broken coal seam and large-section open-off cut in caving workface in some coal mine,the similar simulation test method was adopted to compare and analyze the support effects of two support patterns,and determined truss cable anchor combined support scheme.The numerical simulation method was used to optimize the support parameter, and the industrial test showed that the support technology could effectively control the wall rock deformation of large-section open-off cu... |
