摘要
通过对同煤集团云冈矿8201工作面上覆采空区积水规律的分析与研究,总结出了一套多层采空积水区下回采工作面探放水新技术,力求做到耗用经费最少、耗用时间最短、放水工作最彻底,保证8201工作面在回采期间不受水患影响。
By analyzing and researching overlying goaf water laws in 8201 work face of Yungang Mine of Datong Coal Mine Group, a new technology of water prospection and dewatering of stope face under multilayer goaf water district is summarized, using the least money and the shortest time to finish the most radical drainage work is strived to achieve, 8201 work face that is not affected by the floods is guaranteed.
