Since October 2020, four massive pillar collapses have occurred in limestone mines. Each was accompanied by a powerful air blast and the formation of a large surface sinkhole. Fortunately they did not result in any injuries.
In 2025, powered haulage accidents accounted for 13 of the nation’s 33 mining fatalities (39%) and 426 of the 4,792 nonfatal injuries (9%). These accidents involved equipment such as shuttle cars, locomotives, front end loaders and more.
