Evaluation of white sandstone mechanical behaviour and the energy evolution of prepeak unloading damage

Abstract Deep high-stress roadway excavation under unloading disturbance inevitably leads to damage deterioration of the surrounding rock, which poses a serious threat to its stability. To explore the energy characteristics of white sandstone damaged by peak front unloading, uniaxial compression tes...
