湖南省煤炭坝煤矿现有四对矿井,总涌水量曾达8230m~3/h,单井涌水量曾达3329m~3/h。由于将开拓系统布置在煤层以上长兴组硅质灰岩或煤层以下茅口组灰岩之中,因此有一个坚硬耐压的封闭式泵房。虽然在“文革”前后的十余年中经常因故检修断电,水泵不能运转,水仓小,但由于泵房密封,运输大巷补作水仓,数千米大巷可容纳数万方水,八小时内来电即可排除积水,迅
There are four pairs of coal mines in Coal Dam in Hunan Province. The total water inflow has reached 8230m ~ 3 / h and the single well water inflow has reached 3329m ~ 3 / h. As the development system is arranged above the coal seam Changxing Formation siliceous limestone or below the seam group Maokou limestone, so there is a hard pressure closed pump room. Although in the “Cultural Revolution” before and after more than ten years of regular maintenance of power outages, the pump can not operate, the water tank is small, but due to pump room sealing, transport lane make up water, thousands of meters can accommodate tens of thousands of square Water, call within eight hours to rule out water, fast
