Tests Result of the Prototype Monitoring System for the Operating Parameters of the Powered Roof Support in Real Conditions

Monitoring of operating parameters of machines and devices is recently used more often in hard coal mining. This solution is one of the elements of the intelligent mine concept. This concept means that the enterprise uses innovative technologies while considering economic and social factors. The aim of applying practical solutions under the guiding idea is to increase the efficiency of the production line and the safety of the crew's work. The authors propose introducing a system monitoring the geometrical parameters of the powered roof support. The proposed system fits the requirements of creating an intelligent mine, a plant that meets the global safety and efficiency requirements. The article depicts studies of the underground working conditions of the section geometry monitoring system. The tests contributed to determining sensor installation locations and clarifying the geometric parameters of the measurement and recording system. The system is a solution so far not used in Polish hard coal mining at such a highly advanced level. Based on the measurements, the tested system determined the transverse and longitudinal inclinations of the essential elements of the section. In addition, through the designated angles, the working height of the section in the wall excavation was determined.
