摘要

Mine fires, explosions, spontaneous heating and inundations are among the leading causes of catastrophes (unplanned, temporary sealing and recovery of major mines) and disasters (five or more fatalities). Many reports are available that detail company and agency efforts to determine the causes of catastrophes and reestablish mining operations, but the associated recovery costs are rarely included. Underground coal mine catastrophes are low-probability, high-loss events that happen nearly every year. Case studies of recent catastrophes that occurred from 1987 through 2001 suggest that large underground coal mines are more susceptible to fires and explosions than small mines. On average, when a catastrophe occurs, annual mine production drops by 50 percent, and the rehabilitation efforts can cost as much as 23 million dollars plus 12 dollars per incremental lost metric ton.
