Not that big a deal, depending on what got torn up in the shaft. Same happened at one I worked in. Much smaller, only 1250 ft deep, 50 hands underground. Loading pocket didn't latch the north muck skip dump door correctly and it opened on the way up. Drug the shaft wall until it got to the 400 ft level when it had room and opened, dumping about a third of the 7.5 ton load. Hoistman got bells on both sides, shut down and called me. The shaft repair guys and I rode the top of the mancage up slow to inspect the shaft and find the wreck. Not much to do so we bled pressure off the air and water lines shut down electrical, declutched the muck hoist drums, rode the top of the south skip down and dumped the rest down the shaft. Put a come along on the the door and closed it enough to get it out the top to the mechanics for repair.
Ran a close shaft inspection, cleaned the steel, replaced one guide. Pressured up slow and went back to work. Never shut down mining. Took a shift to replace the bent up skip door to go back to mucking.
But a story like this does sell papers and clicks.
