短服务周期贫水采区水仓硐室优化

Optimization of Chamber for water sump in water-lacking mining area with short service cycle

传统的采区水仓施工方式工程量大,投入高,工期长,针对+435 m一采区水仓服务周期短这一现状,利用准备巷道布置在较厚的B8煤层,在B8煤层中集中布置水仓硐室,水仓上下分层设计配以辅助清仓措施,实现了正规水仓所有功能,经济效益显著。

Traditional mode of water sump in mining area need large amount of construction work,the cost is high,and the cycle of working is long.According the status quo of short service cycle for water sump in No.1 mining area at ＋435 m,the reserved tunnels were proposed to be positioned in B8 coal seam with large thickness,and the water sump was designed as two levels,upper part and lower part,relevant sump cleaning countermeasures was also carried out.All this has realized the full functions of formal water sump, and has gained good economic benefits.
