摘　　要：针对公格营子矿村庄下压煤的充填开采问题,首先依据实际条件选定模拟方法,然后简化建模,设置边界条件和初始条件,选取煤岩体参数并确定监测点。模拟结果表明:公格营子村地表沉陷区域在90 m范围之内,影响很小;地表移动与变形指标中倾斜和水平变形最大,达二级标准,其余指标全在一级内或完全无影响。Aiming at the problem of filling coal mining under Gonggeyingzi village,this paper first selects the simulation method according to the actual conditions,then simplifies the modeling,sets the boundary conditions and initial conditions,selects the parameters of coal and rock and determines the monitoring points. The simulation results show that the subsidence of Gonggeyingzi village is less affected within the range of 90 M. The slope and horizontal deformation of the surface movement and deformation index are the largest,reaching Grade II standard,and the rest of the indicators are all within Grade I or none at all.
