Abstract:

The applied technology, which is the main mixture shaft in Sanshandao gold mine for six months (including horsehead) continuous tunneling and masonry beyond 100 meters,and the comprehensive use of various machine seamlessly matching and continuous work construction organization in shaft tunneling and masonry,is introduced. The shaft development in rock hardness coefficient more than 10 achieves outstanding achievements.

Key words: Main mixture shaft, Freezing construction method, Slurry explosive, Hydraulic formwork
