摘要
罗河铁矿副井井筒施工至364.3 m深度时,遇厚度151.00 m的主含水层,涌水量超过66 m3/h,随着掘进深度的增加井筒涌水量逐渐增大。进行工作面预注浆后,涌水量小于3 m3/h。
Being in the construction of 364. 151.00m--thick, water inflow was over 66 depth of excavation. The water inflow was 3m--deep, auxiliary shaft in Louhe Iron Mine met main aquifer of m3/h and its water inflow continuously increased with the increased below 3 m3/h after working face grouting.
