肥城矿区下组煤距离五灰和奥灰含水层较近，如何在不改变目前矿井排水系统设计的基础上，将这些煤层安全、高效地开采出来，不仅关系到煤矿的生产接续问题，而且关系到人们的生命和财产安全。该文针对肥城矿区下组煤五灰和奥灰水的防治技术途径进行了探讨，提出了五灰和奥灰的防治水措施，对类似条件下水害防治具有借鉴和指导意义。%The under - group coal seams in Feicheng.mining area is close to the 5th limestone and Ordovician limestone aquifers, so how to exploit it safe- ly and efficiently on the base of not changing the present draining system of coal mine is not only relate to the continuous production of the mine, but also the safety of human lifes and properties. The prevention technological approaches of the 5th limestone and Ordovician limestone aiming at the saie mining of the under - group coal seam, have been discussed in this paper, and the proposals of preventing and controlling water were presented, which have refer- ence and guidance for the preventing and controling water hazard in similar conditions.
