Assessment of stress around mine workings at the time of rockburst occurrence

Popis výsledku v původním jazyce

This article deals with a specific rockburst case in the ČSM Mine in the Ostrava-Karviná Coalfield (OKC), Czech Republic. Determination of the magnitude of acting stress is based on the constant weight of the overlying rocks. The rule that the force of stress relief of a mined-out space is equal to the force of additional load in the surrounding unmined area holds true. The magnitude of stress relief is influenced considerably by whether the total thickness of strong overlying layers is disturbed. The state of complete failure of overlying layers is assessed on the basis of undermined surface subsidence measurement. In the case considered, multiple seams were mined; thus, stress transfer to overlying as well as underlying layers is dealt with. In the individual stages of the calculation of acting stresses, the basic rule that the constant weight on the whole affected area, corresponding to the whole roof, was checked. Stress is determined at the time of rockburst occurrence. The maximu
