Abstract

Coal mining business is now faced with various challenges such as export restrictions policy, an increase in value added products, and the decline in market prices of products. To be able to compete, mining companies are expected to increase productivity and efficiency and make continuous improvements in the production process. The purpose of this study was to optimize the production of coal mining in the context of the efficient use of equipment using queueing methode. The research location is in the area of the mining concession contractor in October-November 2015. Production equipment used backhoe excavator is 5 units and 32 units of dump trucks. The simulation results the queuing method generated by the method optimal dump truck needs 25 units. The results of production optimization with queueing method produced mining productivity of 1,208 BCM of overburden per hour with the optimum cost of $ 0909 / BCM.
