摘要
为确保潞宁矿22122风巷掘进安全,消除上方临近的22118工作面采空区积水对巷道掘进影响,在掘进巷道内布置6个探放水钻孔对采空区积水进行疏排。对探放水钻孔施工参数、安全技术措施等进行设计。探放水钻孔共计排放采空区积水8960 m3,消除了上部采空区积水对巷道掘进安全威胁,确保了回风巷正常掘进以及采面生产安全。
To ensure the excavation safety at 22122 ventilation roadway inLuning Colliery,the author introduces the layout of 6 borehole with water detection and release including the construction parameters and safety technical measures in excavation roadway in seeper drainage of goaf,which has discharged 8960 m3 seeper and eliminated the safety threat and guaranteed the normal excavation and safety production.
