以阳煤集团五矿三采区15#煤8303工作面地表移动变形观测站的实测资料为基础,在概率积分法的基础上考虑采动滑移的影响,分析了采动滑移对山区地表移动预计参数及地表移动变形状态的影响。用模拟求参的方法求出概率积分法地表移动变形预计参数;通过对观测站倾向B线与C线的对比分析,得出不同地形特征下山区采动滑移的特点。研究结果表明,在开采沉陷影响下,山区采动滑移是必然发生的;地形起伏越大,采动滑移对水平移动以及水平变形的影响越明显,且水平移动与水平变形的曲线波动越大。
Based on the measured data from the surface movement and deformation observation station of No.3303 Coal Face of No.3 Coal Mining Area, the Third Mining District of Yangmei Group, the influence of mining slip was considered on the basis of probability integral method. The influence of mining slip on the surface of mountainous area The expected parameters of movement and the influence of the surface deformation state. By means of simulation, the parameter of prediction of surface movement and deformation is obtained by the method of probability parameter integration. By comparing the tendency line B and C of the observation station, the characteristics of the mining slip in different mountainous areas are obtained. The results show that mining and subsidence is inevitable in the mountainous area under the influence of mining subsidence. The larger the topographic undulation, the more obvious the effect of mining slip on horizontal movement and horizontal deformation, and the curve of horizontal movement and horizontal deformation fluctuate more Big.
