摘要: 根据29401工作面的地质采矿条件，设计了其地表移动变形观测站。结合该工作面的地质采矿条件，通过分析走向和倾向观测线的地表动态移动变形曲线，获得了该地质采矿条件下地表移动变形规律、角量参数、超前影响规律以及概率积分预测参数。通过分析动态下沉和水平移动曲线的特点，得出山体滑移对该矿区的地表移动变形规律有较大的影响，尤其是对水平移动规律影响较大。Abstract: The surface movement and deformation observation stations of 29401 working face were designed according to its geological and mining conditions. Combined with geological and mining conditions of the working face, the laws of surface movement and deformation, advance affect, angle parameters, as well as probability integral prediction parameters in the conditions were obtained by analyzeing the dynamic surface movement and deformation curves of the strike and dip observation lines. The mountain slip has a larger impact on the mining area of surface movement and deformation and especially for the horizontal movement through the analysis of the characteristics of dynamic subsidence and horizontal movement curve.
