Estimating Mining Factors (Dilution and Ore Loss) in Open

Jan 01, 2007Large open pit mines are driven by the economies of scale that are achieved at the cost of less selectivity in the discrimination of ore and waste. Planning for these mines is facilitated by the use of block models for mine design, scheduling and the conversion of

LARGE SCALE SLOPE STABILITY IN OPEN PIT MINING

Design of open pit slope angles is becoming more and more important as the mining depths of open pits continuously increase. Small changes in the overall pit slope angle have large consequences on the overall economy of the mining operation. A case in particular is the Aitik open pit mine in northern Sweden, which currently faces the design of the overall slope angles for continued mining toward a

Pit Limits The size and shape of the pit depends upon economic factors and design/production constraints. With an increase in price the pit would expand in size assuming all other factors remained constant. The inverse is obviously also true.

Methodology for a Dump Design Optimization in Large

In large-scale open pit mines, the mining process is rather complex and often involves different run-of-mine (ROM) ore and waste material treatmen t downstream. Appropriate areas to place these large amounts of material are limited and their selection and design must serve the environmental factors and economic goals of the long-term mine plans.
