Paper Number: ARMA-2019-0037
... creates the 3D fault zone as a normal type structure in the entire thickness of the model. The normal fault structure and its displacement result in the induced deformation in the model. Several panels of a longwall excavation are virtually placed and excavated adjacent to the fault. The characteristics...

Monitoring the wetting range of water injection is key to study the anisotropic coal seam wetting law, water–gas displacement mechanism, pore fracture structure wetting characteristics, and other important theories. However, only a few studies are conducted on high-precision monitoring of sample...
