摘要
为了保证1031巷掘进安全,提高巷道掘进效率,山西焦煤集团霍州煤电集团晋北煤业有限公司地测科对5上#煤层顶板之上石炭系太原组顶板裂隙水合理有效的探放水施工设计,通过实际应用,放水量达5477m3,解决了巷道上覆岩层裂隙水害,取得显著应用成效。
In order to ensure the safety of 1031 roadway excavation and improve the efficiency of roadway excavation,the Geological Survey Department of Shanxi Coking Coal Group Huozhou Coal and Electricity Group Jinbei Coal Industry Co.,Ltd.has reasonably and effectively designed the construction of exploring and draining water from the roof of Carboniferous Taiyuan Formation above the roof of No.5 coal seam.Through practical application,the amount of water released reaches 5477 m3,which solves the problem of overburden strata in roadway.Fracture water hazard has achieved remarkable application results.
