本文论述了扩建和新建露天矿的开发与发展,着重分析露天矿开采工艺和主体设备机械挖掘机的装备水平,以及露天矿开发对挖掘机的需求。同时又对国内外机械挖掘机的开发和发展状况进行论述,最后提出了开发研制机械挖掘机的可行性和设想。 This paper discusses the development and development of the expansion and construction of new open-pit mines, and focuses on the analysis of open-pit mining technology and the equipment level of the main equipment machinery excavators, as well as the development of open-pit mines on the demand for excavators. At the same time, it discusses the development and development of mechanical excavators at home and abroad. Finally, the feasibility and assumption of the development of mechanical excavators are proposed.
