Faults and igneous intrusions simultaneously encountered in a coal seam can significantly affect the gas emission, i.e., by changing the storage (sorption) and migration properties. Knowledge of the mechanism about their effect will help the gas extraction or methane control in underground coal...

In this paper, it was determined that all of the three-dimensional principal stresses increase with depth and that both the maximum and the minimum stresses tend to be aligned in the horizontal orientation. The numerical simulation model was built using the software FLAC<Superscript>3D</Superscript> to simulate two times,...</superscript>
