Upon closure of the Kazimierz Juliusz hard coal mine and abandonment of open-end mining in the Wieczorek hard coal mine, longwall mining now accounts for nearly 100% of coal mined underground in Poland. Longwall systems are proven and highly effective as long as the appropriate mining machines are selected to be operated under the local geological and mining conditions. The primary consideration is the selection of poweredroofsupport system, and its interactions with the rock strata need constant monitoring. In the Polish hard coal mines

Mining machines suitable for hard coal mining, due to the specifics of this industry must be characterized by very high technical parameters. In particular, it concerns their durability, reliability and availability. Currently used machines approved for operation in underground conditions meet such requirements. Nevertheless, during their operation it is reasonable to conduct supervision and control of work parameters. This applies to both machine manufacturers and users, which is especially important in the event of a failure. Mine employees should be able control of the entire operation process. This control can be effective thanks to a visualization system developed to monitor the working parameters of mining systems. The paper discusses the innovative system and presents the results of efficiency tests. They concerned the visualization of the operation of a powered roof support. The obtained results indicate that the assumed goal of the system has been achieved. The system is built on elements of industrial automation, which guarantees the reliability of the indicated values. Its graphic layout and selection of the presented parameters are also approved. It should also be emphasized that the system can work with currently operating systems and is easy to expand. According to the Authors, the system should find a wide application in practice.
