It's not clear how long the Donkin coal mine in Cape Breton will be shut down after a roof collapse last week. Scott Nauss, senior director of inspection and compliance with the department, said the mine near Glace Bay has been hit with a handful of roof falls in the last six months. 'Large enough to be taken serious'All roof falls are serious, said Nauss, but the latest incident was worse than the previous ones. Kameron Coal employs more than 100 people at the mine, which won't be able to resume operations until the province gives the go-ahead. Coal mining in Cape Breton had been dormant for more than 15 years until the non-unionized Donkin mine opened in February 2017, established to tap into a massive coal deposit under the ocean.
