摘要
为了准确掌握辛置煤矿2-208工作面承压开采底板涌水情况,防止底板涌水事故的发生,根据该工作面具体的地质条件,采用FLAC3D数值模拟软件对底板导水裂隙带发育及突水过程进行了分析,得出工作面具有突水的危险性并且底板注浆改造可有效的治理水害,通过现场实践应用及观测证明取得了很好的治理效果。
In order to accurately grasp the water inrush at the floor of 2-208 working face, Xinzhi Colliery and prevent floor water inrush, the paper analyzes the development of water flowing fractured zone and the process of water inrush by using FLAC3 D numerical simulation software and concludes that the working face has the danger of water inrush and the floor grouting can effectively control the water disaster, which achieves a good effect on water disaster control.
