Description
The shaft for backfilling in the 43 exploratory line on the 200 m level in the Mianhuakang mining area in a hard rock uranium mine in South China could not be excavated by using conventional shaft sinking methode since it was near the fault zone and the rock around it was broken and water-bearing. Therefore, the shaft was excavated by using deep hole blasting. This paper presented the design for the blasting and the construction. (authors)
