Powered roof support in conditions of mining tremors in Upper Silesian Coal Basin – current state in terms of statistical analysis

Coal mining in Upper Silesian Coal Basin (USCB) is conducted in the conditions of frequent mining tremors. The longwall roof support significantly impacts the safety and efficacy of the mining process. The paper presents the assessment of mining tremor hazard, the procedure of designing powered roof supports used in the conditions of tremors, and a method of evaluating supports’ resistance to dynamic overloads. The research was based on analyses carried out by the authors on the data collected during the works carried out by the Department of Extraction Technologies, Rockbursts, and Mining Support. The data was analysed using descriptive statistics.
