摘要
通过概率积分法和FLAC3D数值模拟法计算木瓜井田地下采煤产生的地表移动变形量,定量评价其对地表杨家塔骨干坝的影响程度,在矿井灾害控制、构建和谐社会和经济效益上有着重要的意义。
The deformation of surface moving produced underground coal mining is calculated by probability integration and FLAC^3D numerical simulation method. Evaluating quantitatively its influence on the surface Yangjiata backbone dam has important significance in the mine fire control, building a harmonious society and economic benefits.
