Production Optimization and Simulation of large Open Cast Mines

Abstract

The impact of production optimization and scheduling mainly depends on availability of the machineries; their break-down maintenance schedule and minimization of their idle time i.e. increase in their availability which maximizes their utility. The simulation work-sheet prepare
here for the same purpose only for shovel-dumper transport system. In next phase all the machineries are analyzed of their break-down record by random number distribution for
preventive maintenance so as to minimize the same and increase their availability in work condition to maximize productivity and hence production optimization. Simulation Work-Sheet developed here states that if one or more dumper is added in the system. There is no need for a dumper to wait in the queue. But, before effecting any decision, the cost of having an additional shovel has to compare with the cost due to dumper waiting time. The breakdown of different machineries is analyzed with random number distribution. The different event falls under definite random number distribution range. Such as if random number comes as 1 - 6875 indicates the shovel breakdown and if it comes 6876- 13125 it will be considered as dumper break-down, etc. Hence a clear idea can be made for the break-down of different machineries also precautions can be taken for preventive maintenance to minimize these break-down periods by analyzing this method and thus production can be set as Optimum and steady-state.
