"Hot Muck" Mining Methods
At the Sullivan Mine, recent experience with sulphide fires, locally referred to as "hot muck", has necessitated extensive modifications to pillar mining design and operating procedures. Potentially hot pillars are now being designed and mined to prevent fires. Unusual safety hazards and difficulties are encountered in working with, and adjacent to, existing pillar fires. Operating procedures developed for these conditions have proved successful for safe and continuing production. These changes have minimized the impact of hot ore on current operations and have promise for an improved future.
