OPTIMIZATION OF COAL RECOVERY FROM OPEN PITS.

Journal Article


Abstract


  • The design techniques of the Pit Slope Manual were successfully applied in a case study concerned with optimizing the design of coal mines. The criterion for optimum slopes was based on the financial consequences of each design, i. e. , the resultant benefits and costs. Three alternative designs were analyzed. The first had an average highwall slope angle of 28 degree and a final height of 290 m. The second had a 35 degree slope angle and a 305-m wall height. The third had a 45 degree slope angle and a 320-m wall height. Trade-off between benefits and increased cost of slope instability inherent in steeper slope angles was analyzed for the entire mine life through computer simulation of actual mining operations.
