The theoretical analysis, model experiments and field industrial tests have been carried out. The results show that the charge powder factor could be lowered and the holenumbers can be reduced by 20% or so compared with conventional way. It is very promising to use this new method in the fracture blast.展开更多
文摘In this paper, a new method of fracture blast is presented. The theoretical analysis, model experiments and field industrial tests have been carried out. The results show that the charge powder factor could be lowered and the holenumbers can be reduced by 20% or so compared with conventional way. It is very promising to use this new method in the fracture blast.
