70年代以来,我国煤炭工业开始用机械化综采技术,煤炭生产有了较大发展,但是煤炭贮装运技术仍处于落后地位。大型现代化矿井以贮煤仓装运,轨道衡计量,一般装一列车需要4~6h,计量精度为5%;而地方煤炭集运站多采用皮带机或人工装车,采用划线、容积换算计量,效率低,误差大。世界发达国家如美国、加拿大、英国等的煤炭运输已采用自动化定量斗装车系统。它采用计算机控制、自动计量屏幕显示、液压传动等先进技术,代表了国际80年代装车先进水平。为了适应晋煤外运发
Since the 1970s, China’s coal industry began to use mechanized fully mechanized coal mining technology, there has been greater development, but coal storage and transportation technology is still in a backward position. Large-scale modern coal mines are transported by bunkers and measured by railroad track gauges. Generally, a train needs 4 ~ 6h with a measurement accuracy of 5%; while local coal-handling stations usually use belt conveyors or artificial loading trucks, adopting scribing and volume conversion measurement, Low, big error. Coal transportation in the developed countries such as the United States, Canada, Britain and other countries has adopted an automated quantitative bucket loading system. It uses computer control, automatic measurement of screen display, hydraulic transmission and other advanced technologies, representing the international 80’s loading advanced level. In order to meet the Shanxi coal shipped
