| Abstract: | The designed depth of main shaft of southeast orebody in Chambishi Copper Mine is I lOOm. There are the problems that many aquifers were cut across and large flow of water and pressure. It is the key of shaft construction how to seal the ground water in deep. Aiming at these problems, based on analysis of water inrush properties, the grouting waterproof technology preworkface is put forward, the effect of sealing water is obvious well. The construction period is shortened by this technology, and it provides the refer- ence for the similar projects. |
