摘要
Abstract
The auxiliary shaft of Qianyingzi mine has been injected for six times to prevent leakage of water. However, the total water inflow is still up to 10 m3/h. The transformeod chemical slurry was proposed to solve the leakage of water at the poor injection condition and big difficulty. The transformed chemical slurry is composed of several chemical materials for solidifying sand. A suitable injection plan was proposed based on systematic analysis for geological and hydro-geological conditions of the shaft. Construction parameters were dynamically optimized during construction. And the total water inflow decreased to 0.32 m3/h after injection. The water blocking rate was 97%.关键词
