The Study of a Series of Blasting Funnel Tests of Medium-length Hole Mining
To optimize the existing blasting parameters of medium-length hole drilling, a series of blasting funnel tests are carried out to provide reasonable parameters of unit wastage of explosive, the least resist distance and the most hole-bottom distance for mining design so as to improve the blasting effect and reduce mining cost.
