摘要
针对工作面巷道支护效果不佳或者支护过度导致支护成本高的问题,以某煤矿3号煤层工作面为研究对象,在分析其顶底板、煤层特点情况的基础上,分析了锚杆(索)联合支护的机理,并搭建模型验证所设计支护参数下的顶底板变形及应力情况,经试验应用发现锚杆(索)联合支护能够起到恰当的支护效果。
In view of the problem that the roadway support effect is not good or the support cost is high caused by excessive support,the mechanism of bolt(cable)combined support is analyzed based on the analysis of the characteristics of coal seam No.3 in a coal mine,and the deformation and stress of and the deformation and stress of roof and bottom plate under the designed support parameters are simulated and verified.
