摘要
介绍了3~#掘进工作面需要穿过多处老巷、老空、煤柱,老空水影响施工范围,分析了工作面周围水文地质情况及影响强度。通过分段打钻探放水,采用钢管引流、排水巷截流综合治理措施,解决了老空水向巷道涌水问题。
3# driving face needing to pass through many old alleys, old goaf and coal pillars, and the influence of the old goal water on the construction scope. The hydrogeological conditions around the work face and the influence strength are analyzed. Through the drilling of water in section, the comprehensive treatment measures of steel pipe drainage and drainage drift closure are adopted to solve the problem of water inflow from old goal water to tunnel.
