我国南方广泛分布岩溶充水煤矿床，矿山通常采用强排疏干开采，排水成本极高，更严重的是引发了诸多环境地质问题，造成了巨大的经济损失及恶劣的社会影响。湖南煤业集团辰溪矿业有限公司大坪煤矿为岩溶充水煤矿床，该矿在后期生产过程中，充分利用岩溶发育的不均一性，采取了砌筑水闸墙等措施进行井下堵水，使矿井排水量大幅度减少，地下水位得以区域性恢复，避免了岩溶地面塌陷地质灾害，成功实现了带水压开采。本文概述了大坪煤矿的水文地质、工程地质条件，研究了该矿矿床直接充水含水层的岩溶发育规律；从经济效益、环境效益及社会效益等方面分析了带水压开采的优势；对岩溶充水煤矿床科学、安全开采煤炭资源，建设“两型矿山”有一定指导意义。

Adopting strong emission dewatering in the karst water-filled coal bed ,widely distributed in south of China ,often produces high drainage costs and more seriously ,triggering many environmental geological problems , resulting in huge economic losses and adverse social impact . Daping Coal Mine , Chenxi mining Ltd of Hunan Mining Group , a karst water-filled coal bed , taking advantage of karst heterogeneity ,has taken measures such as masonry walls sluice underground water shutoff in the production process ,which makes mine a displacement greatly reduced and the groundwater level to regional recovery , avoiding the collapse of karst ground geological disasters and achieving with hydraulic mining .Based on the brief conditions of hydrogeology and engineering geology ,this paper studies the karst development law of the direct water-filled aquifers .The benefits on the economic ,environmental and social are studied with mining under water pressure .This paper is of certain guiding significance for karst water-filled coal bed scientific ,safe mining of coal resources and the construction of double-type coal mine .
