摘要
针对东大煤矿16108运输顺槽在掘进前期存在探放水施工效率低、探水设计不合理、探水精度低、巷道水害隐患大等技术问题,在掘进后期对原探放水设计方案进行优化改进。实际应用效果表明:对16108运输顺槽探放水施工设计优化改进后,共计探放上覆12_(下)煤层采空区积水4328 m^(2),探水施工后巷道未出现涌水现象,探放水效果理想。
In view of the technical problems such as low construction efficiency of water exploring and releasing,unreasonable water exploration design,low water exploration precision and great hidden danger of water disaster in the 16108 transportation channel of Dongda Coal Mine in the early stage of excavation,the design scheme of original water exploration and discharge was optimized and improved in the later stage of excavation.The practical application results show that after the optimization and improvement of the construction design of water exploration and discharge along the 16108 transportation channel,a total of 4328 m;of stagnant water in the goaf of the overlying 12;coal seam is put into view,the phenomenon of water gushing does not occur in the roadway after water exploration construction,and the effect of water exploration and discharge is ideal.
