通化煤矿区位于吉林省东南部,现有八矿三厂十六对井口,是吉林省生产焦煤的基地。矿区内中奥陶统马家沟组石灰岩(简称奥灰)大面积分布,由于以往勘探对奥灰缺少控制,奥灰岩溶发育特点及含水性不清,所以生产过程遇奥灰曾多次发生突水淹井事故。奥灰岩溶水对生产威胁较大,搞清奥灰岩溶发育规律及赋水特点,对予防矿井水害和开发利用奥灰水有着重要意义。
Tonghua Coal Mine is located in southeastern Jilin Province. It has 16 pairs of wellheads in the 8th and 8th mines and is the base for producing coking coal in Jilin Province. Large-scale distribution of limestone in the Middle Ordovician Majiagou Formation in the mining area (due to the lack of control of the Ordovician limestone in the past), the development of the limestone karstification and the unclear water-bearing characteristics of the Ordovician Majiagou Formation in the mining area have led to numerous occurrences Water inrush accident. Ordovician limestone karst water is threatening the production, and it is of great significance to find out the law of limestone karst development and the characteristics of water supply. It is of great significance to prevent mine water damage and develop and utilize Ordovician gray water.
