关闭煤矿老空水危害与防治对策

为了防范关闭煤矿老空水可能产生的安全环境危害，应用水文地质学和采矿学理论，研究了关闭煤矿形成的老空水存在的威胁相邻生产矿井安全、资源损失、反向补给含水层、污染水资源等一系列水文地质问题，提出了做好关闭矿井收尾阶段地测工作、采掘资料归档、开展前瞻性研究、注浆加固薄弱煤岩柱、加强水位观测、做好应急管理、注浆封堵反向补给的集中通道以及资源化利用老空水等对策与建议。

Hazards and prevention countermeasures of old goaf water in closed coal mines

In order to prevent the safety and environmental hazards that may be caused by the closure of coal mines，the theories of hydrogeology and mining were used to study the threats to the safety of adjacent production mines，resource loss，and reverse supply of aquifers，a series of hydrogeological problems such as pollution of water resources，proposed to do well in the geological survey work at the closing stage of closing the mine，archived excavation data，carried out forward-looking research，grouting to strengthen weak coal and rock pillars，strengthen water level observation，do emergency management，and grouting countermeasures and suggestions for blocking the centralized channel for reverse supply and resource utilization of old empty water.
