In this study, it has been aimed that producing maximum amount of coal with the lowest cost by determining the optimum dimensions of fully mechanized longwall panels. The optimization, to achieve this goal, has been done by using Operational Research techniques (OR). Optimum panel dimensions problem in the underground coal mining is investigated not only in terms of economy but also in terms of engineering in this study. It is aimed that helping mining industry and mechanized mining operations are performed by the application of mathematical model based on OR in the field. With the help of Operational Research techniques, the parameters that have great impact on fully mechanized longwall panels are determined and categorized. A decision model is developed by using both economic and engineering parameters. It has been shown that the cost of per ton of coal produced can be lowered or how a change in one of the model parameter that effect the cost of coal per ton produced can be easily monitored.
