APPROPRIATE TECHNOLOGY OF OPEN-PIT MINING WITH THE USE OF MOTOR VEHICLES
Proportional development of mining on all benches of working area when using excavator-truck sets is achieved by transition to a benches mining technology on scheme with two subbenches and varying levels of work sites. In deep open pits implementation of this technology will reduce the current volumes of overburden excavation of 10-15% and more, will increase opened-up mineral reserves by 20-50% and reduce the amount of capital mining works on construction of the openings by 2-4 times and will ensure effective use of powerful excavator-car systems.
