- W2382186667 abstract "China's coal mining suffers many problems,s uch as backwardness of technologies and equipments,low recovery rate of mineral resources,high mortality,as well as the retardedness in adopting digital mining.With the concept of scientific mining in mind,this paper analyzes the current status of coal mining,the existing problems,and proposes the concept and the system model of unmanned workface,which combines a high degree of automation and the traditional fully mechanized mining.The technical framework of unmanned workface is outlined.The key technologies are analyzed,including the automatic height-adjustment of shearer,self-positioning and navigation system,automatic identification of coal and rock interface,surface-underground two-way communication,intelligent mining technology,workface component software and models,as well as database technology.Its application is also discussed." @default.
