| Abstract: | Though singl-hole explosion crater model test investigations of equal quantity explosives and different initiations, a conclusion is drawn that millisecond blasting in the blasting hole may increase blasting volume and depth, and improve fragmentary extent. Design methods of millisecond blasting basic parameters are preliminary investigated. |
