In the last decades, numerical modeling has been developed as the common method to investigate solute transport in groundwater. Thereby in science, various numerical procedures have been applied for understanding complex processes of transport in highly heterogeneous aquifers. Beside this, numerical modeling of transport is also standard practice in engineering and consulting. The numerical app...

Natural open joints in rocks commonly present multi-scale self-affine apertures. This geometrical complexity affects fluid transport and heat exchange between the flowing fluid and the surrounding rock. In particular, long range correlations of self-affine apertures induce strong channeling of the flow which influences both mass and heat advection. A key question is to find a geometrical model ...

A series of experiments were performed to determine rock mechanical parameters related to was studied. Experimental results show that the coal seam in the study areas has a relatively low elastic modulus, high Poisson’s ratio, high fragility and is easily broken and compressed. The coal seam is considered as a transversely isotropic medium, since the physical properties in the direction of bedd...
