Abstract/Summary The coal seam gas and underground coal gasification industry has caused concerns with the risk of potential groundwater contamination. Gases leaked from coal seams are thought to be a source of groundwater pollution. However, the basic principles and controlling parameters for gases seepage from deep ground formations to the surface are not fully understood. Microbubble transport, as a possible mechanism for gases transport in the subsurface, is investigated here through a laboratory-scale experiment. Microbubbles were generated from a bubble diffuser and released into a 2D artificial transparent porous medium. The point source of bubble injection was used to simulate the release of gases from geological faults/fractures. The medium's transparency enabled a clear visualization of the bubble pathways. Images captured by cameras were used to facilitate analyses on the bubble transport behavior affected by advection and dispersion.
