摘要(Abstract)：
论述了德兴铜矿深孔台阶爆破机械化装药炮孔内炸药爆速的测试系统和方法．通过炸药孔内爆速的测试，了解炸药的质量及装药孔不同高度炸药爆速的变化规律。确保机械化装药爆破的顺利进行．
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.
