Influence of interface sawtooth angle on the shear behavior of cement mortar coal composite structure

Influence of interface sawtooth angle on the shear behavior of cement mortar coal composite structure

Abstract The influence of interface morphology is of great importance on the shear behavior of the cement mortar-coal composite structure (CCCS) widely distributed in underground mines. In the present research, both the macroscopic- and microscopic failure characteristics of the CCCS with variable i...
