采矿方法的技术经济分析表明,在采矿方法的总劳务费用中,形成底柱的劳务费用平均占20～30％,而放矿和装矿占30～40％。解放硬岩开采中与矿块运输有关的一些课题,是相当复杂的一个实际问题,为此,可将矿块内矿石运输系统划分为相当有代表性的三种类型:自溜放矿和循环运搬、装载和运输(电耙、漏口和电机车运输);振动放矿和运输同振动放矿-带式运输机运输的配套系统。
The technical and economic analysis of the mining methods shows that in the total labor cost of the mining method, the service cost for forming the bottom pillars accounts for an average of 20-30%, while that of ore-dressing and ore-dressing accounts for 30-40%. Some issues related to ore block transportation in the liberation of hard rock mining are quite complicated and practical problems. Therefore, the ore transport system within the ore block can be divided into three representative types: self-slip ore discharge and circulation Transport, loading and transport (electric rakes, leaks and electric locomotive transport); vibrating ore and transport with the vibration of ore - belt transport transport system.
