通过对软岩富含水巷道的防水支护方案进行比较与实验,叙述了施工工艺、支护工艺、防水喷浆材料配比。并对实验结果进行了分析得出,富含水围岩掘进可以采用配比膨胀剂、防水剂法进行防治。
Through the comparison and experiment of water-proof support schemes of soft rock roadway with rich water, the construction technology, supporting technology and the ratio of water-proof grouting material are described. The experimental results are also analyzed. It is concluded that the water-bearing agent can be used to control the water-rich rock excavation.
