On the excavation-induced stress drop in damaged coal considering a coupled yield and failure criterion
Abstract Investigating the stress drop of abutment pressure is the key to a deep quantitative analysis of the discontinuous stress redistribution under mining. In the present study, uniaxial and triaxial compression tests are carried out separately to determine the bulk and shear moduli, the cohesio...
