Ze względu na coraz częstsze występowanie zjawisk dynamicznych w górotworze obudowa podatna wyrobisk górniczych, oprócz obciążeń statycznych narażona jest na działanie obciążeń zmiennych w czasie. Są to obciążenia impulsowe i pulsacyjne. W artykule przedstawiono wyniki badań stanowiskowych złączy ciernych poddanych osiowemu obciążeniu siłą pulsacyjną. W wyniku przeprowadzonych badań wyznaczono charakterystyki...
A numerical modeling approach is proposed for predicting the progressive caving behaviour of strata and performance of powered roof support in a given geo-mining and strata condition. The study suggests that face convergence slope of 75mm/m of face advance may be considered as the maximum permissible value for selection of optimal capacity support for safe working in a given strata condition. The...
