The study of the relation model between elastic modulus and porosity in deep coal seam roof sandstone

Rock mass’s elastic modulus is closely related to its compositions,inner structural characteristics and stress-strain state.By assuming the elastic modulus of pore that as a part of rock is zero,a relational model between the elastic modulus of the whole rock and component as well as volume fraction...
