A NEW METHOD OF FRACTURE BLAST BY TIME-ORDER-IGNITION

摘要

In this paper,a new method of fractureblast is presented.The theoretical analysis,model experiments and field industrial tests havebeen carried out.The results show that thecharge powder factor could be lowered and theholenumbers can be reduced by 20% or so com-pared with conventional way.It is very promis-ing to use this new method in the fracture blast.
