CHINA MINE ENGINEERING

Gushan iron ore mine selects upward horizontal stratified filling mining method and upward approach filling mining method to mine under different geological conditions, in order to optimize the structure of the quarry, this study proposes 3-4 kinds of quarry parameter schemes by means of theoretical analysis and engineering analogies, and then according to numerical simulation means, selects the suitable quarry scheme from the aspects of quarry safety, productivity and production arrangement, optimizes the layout, and provides design references for mine provide design reference for safe and efficient mining and reduce loss depletion.
