蒲白矿务局白水矿王家尧头村庄下煤层开采属于厚黄土覆盖层下厚煤层开采类型。针对其地质、开采条件,应用关键层及煤柱强度理论,结合相似材料模拟试验,数值计算分析、影响函数预计进行分析,确定了控制开采损害的开采法及相关参数。结果表明,运用倾斜条带开采方案可以保证关键层不受破坏,能够有效地控制地表移动和变形,从而控制地表坡体滑坡的发生,保证了地表建筑物的正常使用及矿区的安全生产,取得了显著的技术经济效果。
Pu Bai Mining Bureau Baishui mine Wang Jia Yao Tau village under the thick seam mining belongs to thick seam mining type. According to the geology and mining conditions, the key layer and coal pillar strength theory are applied, and the simulation experiments of similar materials, numerical calculation and analysis, and the impact function are expected to be analyzed, and the mining methods and relevant parameters for controlling mining damage are determined. The results show that using inclined strip mining scheme can ensure that the key layer is not damaged and can effectively control the movement and deformation of the ground surface so as to control the landslide of the surface slope and ensure the normal use of the surface buildings and the safe production in the mining area. Significant technical and economic results.
