Based on SEM observance,the methods of low-temperature nitrogen and isothermal adsorption were used to test and analyze the coal samples of Hancheng,and pore st
Using an MTS 815 testing machine, the deformation and failure behavior of a rock-coal-rock combined body containing a weak coal interlayer has been investigated
To discuss the domino instability effect and large area roof falling and roof accidents of surrounding rock-coal pillars in a room-and-pillar gob, the equilibri
Investigation of temperature effect on mechanical parameters of coal is very important for understanding the mechanical response of coal bed at high temperature
For a study of the movement and deformation of coal-rock mass and low protected seams below a stope,as well as for fracture developments and rules of evolution
