美国矿业局在硬岩不用炸药爆破破碎方面有一项长期规划。此项研究系采用水射流和机械法进行破碎。其目的是发展硬岩连续挖掘设备和方法,以取代目前大多数地下硬岩矿山的钻孔-爆破-装岩循环系统。钻孔-爆破-装岩系统这种系统上个世纪就已在矿山应用,并还将继续下去。它
The U.S. Bureau of Mines has a long-term plan for hard rock blasting without explosives. The study was conducted using water jets and mechanical methods. Its purpose is to develop continuous hard rock excavation equipment and methods to replace the current drilling-blasting-rock loading system in most of the underground hard rock mines. Drilling - Blasting - Rock Loading System This system has been used in mines for the last century and will continue. it
