【摘要】 针对朝川矿一井主皮带斜井明槽段施工完毕后第四系潜水通过疏松回填土渗漏涌入斜井井筒内的现象,朝川矿采用注浆加固手段,对明槽段进行地面注浆加固。通过注浆加固,一井斜井明槽段井筒涌水量由最初的35m~3/h,降低至1m~3/h以下,注浆堵水效果明显,值得推广。更多还原

【Abstract】 According to the situation that a hole in the Zhaochuan mine main belt inclined Ming slot construction after the completion of Quaternary diving through loose phenomenon within the well-bore of inclined well of the back-fill soil leakage into the Zhaochuan mine grouting reinforcement method, ground grouting reinforcement on the Ming slot. By grouting reinforcement, the inclined well Ming slot wellbore water inflow from the original 35 m~3/h, reduced to less than 1 m~3/h, grouting water plugging effect obviously. It is worth promoting.更多还原
