鑫臻煤矿保水开采方案研究

Water-preserved mining scheme of Xinzhen Coal Mine

  • 摘要: 突水和排水不仅危害矿井的安全运行,并且会造成水资源浪费和其它水资源的污染,故开展保水开采对矿井可持续发展具有重要实践意义。首先对鑫臻煤矿水文地质条件进行分析,明确矿井含水层、隔水层及其水文地质工程地质条件。在分析采动对含水层影响基础上,从保水开采方法和矿井水资源利用两方面确定鑫臻煤矿保水开采方案。最后对鑫臻煤矿保水开采方案从技术方面、经济方面、环境及社会效益方面进行综合分析。结果表明,裂隙水为矿井水资源保护主要目标;井田区内采空区和井田临近采空区为重点防治对象;采用留设防隔水煤柱、充填保水、疏导排水和矿井水资源化利用模式相结合的保水采煤方案合理可行。

     

    Abstract: Water inrush and drainage not only pose a threat to the safe operation of mines but also lead to water resource waste and pollution of other water bodies.Thus, implementing water-preserved mining holds significant practical implications for the sustainable development of mines.Therefore, this paper firstly analyzes the hydrogeological conditions of Xinzhen Mine, clarifying the aquifers, aquitards, and their hydrogeological and engineering geological conditions.Based on an analysis of the impact of mining activities on aquifers, a water-preserved mining plan for Xinzhen Mine is formulated from two aspects: water-preserved mining methods and mine water resource utilization.Finally, a comprehensive analysis of the water-preserved mining plan for Xinzhen Mine is conducted in terms of technology, economics, environment, and social benefits.The results show that: fissure water is the primary target for mine water resource protection; goaf areas within the mining area and adjacent goaf areas are the key prevention and control targets; and the water-preserved coal mining plan that combines the establishment of water-resistant coal pillars, water-filled water preservation, drainage diversion, and mine water resource utilization is reasonable and feasible.
