The paper presents the results of research on the geometry measurement system of a powered roof support using inclinometers that meet the requirements of the ATEX directive. Coal mining is most often carried out using a mechanized longwall system. The longwall system includes basic machines, such as a longwall shearer, a longwall conveyor, and a powered roof support that secures the roof of the excavation...
Safety aspects of mining personnel as well as the safety of the coal mining processes are presented. A mechanised longwall system is commonly used in the coal mining industry. The system consists of the basic machinery, such as a shear loader, an armoured face conveyor, and a powered roof support, which protects the roof of workings. The powered roof support consists of hydraulically or electro-hydraulically...
