摘    要:针对晋城矿区主采的山西组3号煤层和太原组15号煤层,受煤系地层基底奥陶系灰岩承压水威胁实际,通过对奥陶系峰峰组、马家沟组灰岩富水性、地下水赋存特征进行研究,分析了奥陶系灰岩水对3号、15号煤层开采的充水影响,评价了带压开采安全性并提出了相应的防治技术措施,为区内3号、15号煤层带压开采与防治提供了科学依据。

关 键 词:晋城矿区  奥陶系灰岩  富水性  赋存特征  带压开采

Abstract:In view of the fact that the No.3 coal seam of Shanxi Formation and No.15 coal seam of Taiyuan Formation mainly mined in Jincheng Mining Area,which are threatened by the confined water of Ordovician limestone at the base of coal measure strata,based on the research on the water abundance and groundwater storage characteristics of Ordovician Fengfeng Formation and Majiagou Formation limestone,the influence of Ordovician limestone water on the mining of No.3 and No.15 coal seams were analyzed,the safety of mining under pressure was evaluated,and the corresponding prevention and control technical measures were put forward,providing scientific basis for pressure-bearing mining and prevention of No.3 and No.15 coal seams in Jincheng Mining Area.
Keywords:  Jincheng Mining Area   Ordovician limestone   watery   occurrence characteristics   pressure-bearing mining
