Abstract
Abstract. The coal mining business is currently faced with various challenges such as export spending
policies, increasing product value added, and decreasing product market prices. In order to be able to
compete, mining companies are required to increase productivity and increase and enhance sustainable
production processes. In the mining process, the draw of dump truck equipment and loading equipment
will determine the continuity of production which increases productivity and efficiency. The purpose of this
study is to optimize production in coal mining in order to efficiently use equipment by using linear
programming methods. The location of the study was conducted in the PT Surya Global Makmur Jobsite
Pemusiran mining concession area, Sarolangun Regency, Jambi Province in October 2019. The loading
equipment used was five units of backhoe excavators and 22 units of dump trucks. The results of the
simulation with linear programming methods are 20 units of conveyance. The results of production
optimization with the linear programming method produce overburden productivity of 681.16 BCM per
hour with an optimal cost of 0.86 USD / BCM.
