桌子山煤田下组煤开采受奥灰承压水威胁程度研究

Research on Threatened Degree of Lower coal group coal mining under the threat of Ordovician confined water in Zhuozishan Coal Mine

分析研究了桌子山煤田奥灰岩溶水的水文地质特征,重点分析了区内下组煤开采带奥灰水压情况,隔水层发育特征及受奥灰岩溶水威胁程度,对区内下组煤开采受奥灰水威胁程度进行了分区,为桌子山煤田下组煤开采奥灰水防治提供了理论依据。

Researched the hydrogeological characteristics of Ordovician limestone karstic water in Zhuozishan Coal Mine. Anal- ysis the waterpressure of Ordovician limestone water,the aquiclude characteristics and the threat level of Ordovician limestone water during the lower group coal mining,Based on the threat degree divides different regions. The research results provide the theoretical basis for the prevention and control of Ordovician limestone water in Zhuozishan Coal Mine during the lower group coal mining.
