Rigid foam for mines
To increase safety and productivity in mining, potential uses and hazards of rigid foam were investigated by Bureau of Mines Experimental Coal Mine; this research resulted in development of chemical formulations, spraying equipment, and application procedures that permit safe and effective use of urethane foams for improving mine ventilation, for reducing weathering of mine rock and steel, for constructing seals in fire areas, and for thermal insulation.
