| 摘 要： | 为保障五阳煤矿在承压水威胁条件下进行安全开采,从主要含水层、底板隔水层阻水性能和突水通道3个方面对井田的水文地质特征进行了分析,采用突水系数法对底板的突水危险性进行了安全评价,结果表明:五阳煤矿3号煤底板奥灰岩岩溶水突水危险性极大,尤其在采动影响下,底板破裂严重,发生突水的危险性进一步增加.以此提出了五阳煤矿底板突水防治有效措施.

| Abstract: | In order to ensure the safe mining under the threat of the pressurized water in Wuyang Coal Mine,from the three aspects of the mail aquifers,the water-resisting performances of the floor water isolated layer and the water inrush channel,the paper analyzed the hydrogeology features of the mine coalfield.The water inrush coefficient method was applied to the safety evaluation of the water inrush danger from the floor.The evaluation results showed that there was a high danger of the Ordovician karst water inru... |
