【Abstract】 The paper deals with the measuring method of detonation velocity of the explosives loaded mechanically into longholes in -high bench blasting of Dexing Copper Mine. Through the measuring of detonation velocity, there is a good realization for the performance of a loading truck, the quality of emulsion explosives and the variation of detonation velocity in different loading heights in longholes. Based on above, the mechainzedly charging blasting is quaranteed to process smoothly.更多还原
