针对柠条塔煤矿在黄土沟壑地形条件下的地表岩移参数求取问题,通过建立地表岩移观测站,计算出其超前影响距和超前影响角、最大下沉速度、滞后角及地表移动持续时间。并利用坡体稳定性分析及计算机反演模拟的方法,对概率积分参数进行修正,修正后的概率积分参数与实测结果相吻合。研究表明:在黄土沟壑地形条件下求取地表岩移参数时需考虑坡体稳定性及其滑移附加量的影响。
In order to solve the problem of surface rock movement parameters under the condition of loess gully topography in the Tieta tower coal mine, the influence angle and leading influence angle, maximum sinkage velocity, retard angle and surface movement are calculated through the establishment of surface rock movement observation station time. The method of slope stability analysis and computer inversion simulation is used to correct the probability integral parameter. The corrected probability integral parameter is consistent with the measured result. The results show that the stability of slope and its additional slip should be taken into account when determining the parameters of surface rock movement under the loess gully topography.
