Modeling for the Steady State Production of Large Open Cast Mines- Case Study

When mining company gets the lease of a mineral deposit, the difficult is then how to mine and process that deposit the optimum way. The main problem facing managers or engineers who must select on equipment selection, mine plant site and long range scheduling is how one can optimize a property not only in terms of efficiency but also as to project duration.


With the advanced technology different types of mechanization such as dumper, shovel, dozer, drill machine etc. Use of more machineries leads to more complexity in operation and as result it is very difficult to make the proper matching of those equipment and these Machineries are very costly. Hence unless they are properly matched reduction in production cost is very difficult. Increase in idle times of machineries leads to increase in production cost. In order to reduce the idle time or waiting time, the number of machineries may be increased. Due to greater cost of machineries additional investment is needed which ultimately contribute in higher production cost. Thus, unless you getting a perfect matching with optimum number of equipments reduction in production cost is impossible. So, we need to analyses the operations of equipments by repairing, considering their break down periods, maintenance of preventive maintenance, availability of spare-parts, efficiencies of operators and management philosophy etc. This study is based on use Monte –Carlo technique in operation of shovel- dumper combination.
