Mining Publication: Mine Fires - Measuring the Efficacy of Gas-Enhanced Foam
NIOSH conducted research with US Foam Technologies, Inc., and On Site Gas Systems, Inc., on the remote application of extinguishing agents with the intent of improving deployment strategies to limit miner exposure and to help ensure the best possible outcome during a mine fire. Full-scale in-mine experiments were conducted in the NIOSH Lake Lynn Experimental Mine to determine the flow characteristics, stability, and fire suppression capability of gas-enhanced foam. The in-mine experimental work was designed to evaluate movement of gas-enhanced foam through mine workings closely simulating an underground coal mine environment and how long gas-enhanced foam would remain stable. This paper presents results of the experiments and provides valuable insight into mine fire deployment strategies for gas-enhanced foam technology.
