峰峰三矿是受奥灰水威胁及煤系大青灰岩充水影响的矿井。为了有效地进行防治水,笔者根据生产及勘探获得的资料,对该矿中央区的大青灰岩水文地质条件作一分析,并提出一些认识,不妥之处,请批评指正。 一、地质和水文地质概况 峰峰三矿位于鼓山东麓最南端,滏阳河与漳河地表分水岭处,北距闻名的黑龙洞泉群11.5km。井田长7km,宽0.73～2.3km,面积为10.6 km~2。 该区属大陆性半干旱气侯,一般年份 Fengfeng mine is affected by the threat of Ordovician gray water and coal-bearing large limestone mines affected. In order to effectively prevent and control water, based on the data obtained from the production and exploration, the author analyzes the hydrogeological conditions of the large Qingyan rock in the central area of ​​the mine and puts forward some suggestions on the understanding and improper treatment. Please criticize and correct it. I. Overview of Geology and Hydrogeology Fengfeng No.3 Mine is located at the southernmost tip of Gushan Mountain at the foot of the surface watershed of the Xingyang River and the Zhanghe River and is 11.5km north of the famous Heilongdongquan. Well field length 7km, width 0.73 ~ 2.3km, an area of ​​10.6 km ~ 2. The area is a continental semi-arid climate, the general year
