Survey on underground geotechnology during transition to the development of deep reserves of inclined copper pyrite deposits
The need to maintain Urup underground mine production capacity determines the transition to the working out of deep reserves of copper pyrite ore, efficiency of development of which largely depends on the proper selection of schemes of opening and development technology
Comparison of volumes and timing of construction for two constructed variants of opening showed that the gradual opening of the ore by sloping with road transport provides a timely transition to the working out of deep mine reserves without any loss of production capacity
Summary
As a result of technical and economic comparison of ten constructed variants of ore mining technology by the criterion of maximum profit, referred to the 1 ton of redeemable balance reserves, authors established the effectiveness of the development of the system of sublevel caving of the ore bodies for average power and room-and-pillar system for low-power stations The use of these options of technology can significantly improve the technical and economic indicators of ore extraction and obtain acceptable average weighted ore recoveries (loss of 17 %, 22 % dilution) using self-propelled equipment and disposal of rocks from tunneling and cleaning recess in the goaf of waste chambers. Необходимость поддержания производственной мощности Урупского подземного рудника обусловливает переход к отработке глубокозалегающих запасов медноколчеданных руд, эффективность освоения которых во многом зависит от правильного выбора схемы вскрытия и технологии отработки.
