Development of Potential Remote Coal Mine Fire Response Measures: Use of Multiple Passive Source Tracers and Simulation of High Expansion Foam Flow in Simulated Gob Material
… the mine openings. Injection of high expansion foam into the gob from the surface has potential to improve extinguishment of the fire and reduce the time needed to bring the mine back to an operational state. The applicability of this method requires computational modeling and field testing. The …

Numerical Simulation of High Expansion Foam Into Conduits and Mine Openings
High expansion foam (Hi-Ex) is a firefighting technology that has been widely used for fire suppression in underground locations. Hi-ex foam can be applied remotely through boreholes from the surface reducing firefighter exposure to fires. Despite the experimental studies that have been carried out …

Removal of metal ions from solution by foam fractionation methods
Foam separation is used as a method for separation of solute from liquid solutions. The physical chemistry of a foam-liquid system was investigated including studies of foam density, foam stability and foam drainage, and the counter-current flow of liquid and foam. The experimental results obtained …
