一、前言随着矿山开采工作的进行,国内不少露天矿即将转入深部开采,有的深度已达100米,采场逐渐变深变窄,运距增长,运输成本增加。有的矿山在上部开采时已用铁路运输开拓系统,转入深凹部分后,是继续选用铁路运输还是用汽车运输。××铁矿这次开采运输系统技术经济评价即是面临这个问题。铁路运输与汽车运输在技术上、经济上到底如何比较,我们的看法是结合国情和矿山具体条件具体分析。汽车运输有优点,它机动灵活、爬坡能力强,但吨公里运费高。
I. INTRODUCTION With the progress of mining work, many domestic open-pit mines are going to be deep-seated. Some of them have reached a depth of 100 meters. The stope gradually becomes deeper and narrower, and the distance increases and the transportation cost increases. Some mines in the upper mining has been used to open up the system of rail transport, into the deep part, is to continue to use rail transport or motor transport. × × iron ore mining technology and economic evaluation of the mining system is facing this problem. The technical and economic comparison of rail transport with that of motor transport is based on the analysis of specific conditions of our country and mine. Car transport has advantages, it is flexible, climbing ability, but tons of high shipping costs.
