Coal mining industry is important economic field for prosperity and
development of country economics, however providing safety, productivity and environmental sustainability of underground coal mining process is highly complex issue. It can be achieved through complex automation. In order to design control system hardware a mathematical model of frontal shearer has to be examined. The kinematic and dynamic models of frontal shearer (FEM-5) has been evaluated and then the systems with different initial parameters has been tested for stability according to Hurwitz criterium. The system has been examined for closed-loop and opeded-loop stability with different values of proportional controller which has shown its stability in marginal position...
