Silver mining in the roadway excavation techniques, although basically mechanized, but the lower level. Currently shaft excavation is still a traditional jackhammer drill, rock grab grab mounted electric slag machine operating, ordinary type or bucket slag and other technology-based promotion. In the supporting technology, the current wood and concrete support is still large proportion, bolting use only in some mines, widely used abroad anchor sprayed with metal mesh and other new technologies not yet adopted country. Deposits due to the different geological conditions and mining electric technical conditions Cinder machine, a wide range of electric mining method Cinder machine parts, different mining methods, its mining process, mining machinery, mining area of ??roadway layout and mining sequence is different. Inappropriate choice of mining method, the long-term impact of the mine production of technical indicators and economic benefits. The main production processes are required to choose the appropriate machinery and equipment, in order to get the best economic results. Xining electric slag machine _ _ electric crawler machine Cinder Cinder machine provided by Gongyi City Xinhua Machinery Factory.
