The paper presents two methods for periodical identification of the dependence between haulage speed and loading torque of the shearer for periodical corrections of control algorithms. These algorithms are useful for working with small microprocessor-based systems. The paper is concluded with results of identification using above methodsand with discussion about their merits and demerits. The longwall mining system is the basic exploita-tion system used in coal mining in Poland. The quantity of coal produced by this system, using a shearer loader as a cutter-loader machine is esti-mated at 170 million tones per year. For this rea-son scientific research concerning these machines is of major practical significance.
