同忻煤矿地下水库建设与水资源保护技术研究

Underground Reservoir Construction and Water Resources Protection in Tongxin Coal Mine

煤炭资源的大规模开采导致水资源短缺问题和煤炭资源开发利用之间的矛盾日益严峻。本文通过对同忻煤矿井下涌水的地球化学分析,结合实际生产需求,提出建设地下水库,实现"煤水共采"的新思路。井下水库的建设实施,可将矿井废水转化为日常生产和消防用水,可有效缓解地面污水处理压力,降低煤炭生产成本,一定程度上减轻上覆侏罗系及同层采空区积水的威胁,进一步保障矿井防治水安全。此方法还保护了矿区生态环境,为干旱地区水资源保护和资源开发利用提供参考。

The status of coal as its main energy source is unshakable in the short term. The large-scale mining of coal resources has led to the more prominent contradiction between the shortage of water resources and the development and utilization of coal resources. On the geochemical analysis of the underground water and actual production demand in Tongxin Coal Mine, this study put forward a new way to construct underground reservoirs to achieve "coal and water co-mining". Through the construction and implementation of the reservoirs, mine wastewater could be converted into daily production and fire-fighting water, which could effectively alleviate the pressure of surface sewage treatment, reduce production costs, and, to a certain extent, decrease the threat of water accumulation in the overlying Jurassic and the goaf in the same layer in order to further ensure the safety of mine water prevention and control. Meanwhile, it could protect the ecological environment of the mining area, providing a reference for the protection of water resources and the development and utilization of coal resources in arid areas.
