ABSTRACT
Current trends in support of mine workings with increasing depth, and geo-mechanical design requirements for strain-power characteristics support for hard geological conditions are considered. Priority parameters of availability support and determined the effective intervals required deformation-force characteristics to reduce steel intensity of mine workings is proved. The design features and the basic parameters of supports new technological level ovoid design are given. The results of industrial application ovoid roof supports for deep mines of Ukraine are presented.
