The process of roadway surrounding rock deformation and instability is always accompanied by energy changes. and the energy transformation of surrounding rock directly drives its deformation and failure. In order to realize the stability control of mining roadway. the distribution of elastic strain energy and plastic strain energy of surrounding rock was analyzed by using FLAC3D numer... https://www.roneverhart.com/C7-Corvette-Stingray-Lapel-Pin-Crossed-Flags/
