一、任务来源 为了开发我国露天矿山资源和革新采矿工艺,提高劳动生产率,降低采矿成本。一机部矿山工程局和原燃化部基建组于1972年联合召开会议,决定试制斗轮—胶带机连续开采成套设备,用来代替旧的单斗—铁道运输系统。两部决定这项新工艺将在广东茂名石油公司露天矿开采油页岩时试用。 连续开采新工艺包括采油页岩矿石,排运剥离表层和废页岩排弃的三套运输系统。 采矿系统的工艺流程是:斗轮机挖掘油页岩→移置式胶带机→干线胶带机→炼油 First, the source of the task In order to develop open-pit mine resources and innovation of mining technology, improve labor productivity and reduce mining costs. A mechanized mining engineering bureau and the original combustion of the basic unit construction group held a meeting in 1972, decided to trial bucket wheel - tape machine continuous mining complete sets of equipment, used to replace the old single bucket - railway transport system. The two companies decided that the new process will be used when oil shale from the Maoming Oilfield open pit in Guangdong is being exploited. New processes for continuous mining include the production of three shale ores, the removal of peeled off surface skins, and the disposal of three waste systems. Mining system processes are: Bucket bucket excavation of oil shale → Displacement tape machine → Trunk tape machine → Refining
