MSHA Launches Pillar Collapse Initiative with Seminars
[Click image to enlarge]
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. Another massive pillar collapse occurred in 2015, and in that instance three miners were seriously injured by the air blast. All of these collapses occurred where floor mining, or benching, had substantially increased the height of the pillars. Three of them occurred in “legacy” areas where mining was completed many years ago.
MSHA has resources available to raise awareness and avoid these accidents at underground mines, particularly limestone mines, that can result in areas where benching has occurred. Please use resources on this page to help avoid the dangers of pillar collapses.
