浅析平硐穿越采空区的探放水技术

Brief Analysis on the Water Detection and Release Technology through the Goaf

为解除平硐在道路交通隧道、矿山开发中穿越富含岩溶水地层或受老窑水影响的区域时的相关水害威胁,实现安全施工,需进行合理的探放水设计。通过布置钻场,实现掌子面与钻场探放水钻孔的平行施工,提高探放水效率;通过科学设计钻孔参数,准确掌握平硐周围采空区分布情况,确保平硐的安全施工;钻场作为探放水钻孔的施工场所,平硐完工后钻场也可作为躲避硐室,实现钻场的综合利用。

In order to relieve the threat of water damage caused by flat cave in road traffic tunnels and mine development through areas rich in karst water or affected by goaf water, and to achieve safe construction, so corresponding water detection and release technology design is required. By arranging the drilling field, the parallel construction of tunnel face and water detection and water release drilling of drilling field can be realized, and the efficiency of the water detection and release technology is improved. By scientifically designing the drilling parameters, the distribution of the goaf around the flat cave can be accurately grasped to ensure the safe construction of the flat cave. The drilling field is used as a construction site for water detection and water release drilling. After the completion of the flat cave, the drilling field can be used as a shelter to realize the comprehensive utilization of the drilling field.
