破碎露天矿中凿岩爆破法崩矿所产生的大块,是露天采矿作业中急待解决的技术问题。最普通应用的破碎方法是爆破法,但是这种方法具有一系列的缺点:成本高,达4.2卢布/米~3;爆破时产生许多飞散碎石,可能损坏露天设备和管道,等等。应用高能冲击法破碎大块具有以下特点:破碎能耗很-低(能耗系数为0.07);破碎时飞散的碎块少;设备的机动性好。 Broken open-pit mine blasting blasting method produced by large chunks, open-pit mining operations is an urgent technical solution. The most common method of crushing is the blasting method, but this method has a number of drawbacks: a high cost of 4.2 rubles / m³; blasting generates many flying debris that can damage open-air equipment and pipes, and so on. The use of high-energy impact crushing has the following characteristics: Crushing energy is very low - (energy coefficient of 0.07); broken less scattered fragments; equipment mobility is good.
