摘要
保德煤矿在收集分析其水文地质资料基础上,结合近几年的补充勘探,分析了保德煤矿11号煤层开采的水文地质条件,研究了矿井充水因素、奥灰质特征、底板突水机理和预测方式;得出了保德煤矿防治奥灰水的重点是治理导水通道,并对矿井防治水措施提出了建议。
On the basis of hydro-geological data in Baode mine,the paper studies hydro-geological condition,water filling factors,Ordovician limestone features,and floor strata water-inrush mechanism and predication for seam 11 mining.At last,some suggestions are proposed for the water prevention and control.
