为获取云驾岭矿区合理的岩层力学参数,选择了数值模拟几个关键参数作为反演因子,对各因子的变化水平进行了合理划分。采用正交试验法设计了试验方案,以地表走向观测线最大下沉值作为监测指标。通过逐一模拟计算及统计分析,得出了各因子水平的改变对模拟结果影响的显著性程度,确定了反演因子的合理组合,并通过实验进行了验证。
In order to obtain the reasonable mechanical parameters of rock strata in Yunjialing coal mine, several parameters are reasonable selected as the inversion factors, and the change level of each factor was divided scientifically. Then, the test scheme was designed by orthogonal test method, and the maximum subsidence value of the surface strike observation line is selected as the monitoring index.
