摘 要:常村王庄煤矿S5-12工作面部分位于村庄保护煤柱。为实现部分充填开采后的地表沉陷变形可视化,采用概率积分法、距离幂次反比法和矩形网格模型的等值线绘制方法建立了部分充填开采时的地表沉陷变形预测方法。通过建立的预测方法计算得到满足地表建筑物安全时的煤柱内可采厚度为3.5 m,应用等效采高计算模型反推出此时的矸石最小充填高度为4.03 m。Part of the S5-12 working face in Wangzhuang coal mine is located in the village’s protective coalpillar, To realize visualization of surface subsidence deformation after part of filling mining,partial filling min-ing surface subsidence deformation prediction method is established by using the probability integral method,distance power inverse ratio method and the contour-map method of rectangular grid model, By establishingthe prediction method calculate the mining thickness within the coal pillar in the safety of the surface buildingis 3.5 m The equivalent mining model is applied to backstep the gangue minimum filling height is 4.03 m.
