How recent Magma Mine fire was brought under control
Fire was discovered at 2900 ft level of Magma copper mine, Arizona, Dec 2 1961; fire was successfully contained and mine purged of smoke and fumes on Feb 7 1962; this was accomplished by sealing off critical section with air tight concrete bulkheads, temporary brattice bulkheads, filling raises with muck and sealing with clay, grouting muck in raises, and grouting all suspect fractures that would serve to feed oxygen to flames; ventilation proved to be decisive and most important factor in controlling fire.
