摘要
利用ADINA软件对高家梁煤矿2号煤层软岩巷道支护稳定和变形过程进行了动态仿真模拟,根据模拟结果分析了高家梁煤矿目前采用的"锚网喷带"联合支护的稳定性与合理性,并结合现场监测数据确定出最佳的二次支护时间,修正了以往根据经验和距迎头距离确定二次支护时间的僵化模式。
We use ADINA software to study dynamic simulation of soft rock roadway stability and deformation process for No. 2 seam from Gaojialiang coal mine. On the base of the result of simulation, we analyzed the stability and rationality of the combined support, ＂anchor net belt spray＂, which is widely applied in mining engineering. We obtained the best secondary support time using field monitoring data. We modified conventional pattern, which determine secondary support time on the base of experience and distance from head.
