摘要
以兖州矿区东滩煤矿封闭不良钻孔为研究对象,在采动影响下,对封闭不良钻孔进行了FLAC^(3D)数值模拟研究,随着工作面的推进,从支承压力分布、塑性变形和钻孔压力分布3个方面进行分析。
On the influence of digging, FLAC3D numerical simulation was analyzed on the risk of water inrush from poor sealing borehole in Dongtan coal mine of Yanzhou mining area. By work face advanced, the changes were found on the distribution of support pressure, plastic deformation and borehole pressure.
