某矿井区内地下水赋水情况复杂,涌水量及水压均较大,为了保证矿井安全生产,需查明该矿井的水文地质条件并制定行之有效的防冶水措施。主要研究了首采工作面煤层采动前、后含水层变化规律及导水裂隙带发育规律,以超前探水、疏水降压、合理留设防水煤岩柱等防治水措施来指导企业进行水害安全防治,通过多种防治水措施的综合运用,杜绝了矿井重大水害事故,为矿井带来了较大的经济和社会效益。
In a mine area, the groundwater infiltration is complicated with a large amount of water inflow and water pressure. In order to ensure the safe production of a mine, the hydrogeological conditions of the mine need to be identified and effective measures for prevention and control of the occurrence of watermelon are established. Mainly studied the first mining face coal mining before and after mining changes in the law and aqueduct water rift zone development law to advance the water, water and pressure relief, water and other rational prevention of water column to prevent water to guide enterprises to water hazards Through the comprehensive utilization of a variety of water control measures, it has eliminated major water damage accidents in mines and brought great economic and social benefits to the mines.
