The Mechanical model of a new support
Abstract: This paper puts forward a new kind of roadway supporting (i.e. mutual resist support) design proposal, and also established the mechanical model of upper frame, side frame and under frame respectively. And finally it makes a comprehensive evaluation of the stress on this complex combination, which proved the new support has a good supporting performance.?????
