在露天矿山的开采中,运输工作占居很重要的地位。运输设备的投资占总投资的2/3左右,所需劳动力占50～60%左右,矿石运输成本占总成本的50%左右。无论是山坡露天矿,还是凹陷露天矿,传统运输工作都是采用单一的间断工艺,如铁路运输,汽车运输等。随着露天矿规模的不断扩大,这些传统的运输方式将束缚着劳动生产率的进一步提高。采用铁路运输时,电铲的停工事实上是不可避免的。以苏联为例,每班内,机车的纯运行时间只
In open pit mining, transportation occupies a very important position. Transport equipment investment accounts for about 2/3 of the total investment, labor force required about 50 ~ 60%, ore transportation costs account for about 50% of the total cost. Whether it is a hillside open-pit mine or a pit open-pit mine, the traditional transport work uses a single intermittent process, such as railway transport and motor transport. With the continuous expansion of the size of open-pit mines, these traditional modes of transportation will hamper the further improvement of labor productivity. When using rail transport, the shovel shutdown is in fact inevitable. In the Soviet Union, for example, each class, the pure running time locomotive only
