An Edmonton-based company has been fined $120,000 after a worker was seriously injured at a coal mine near Estevan.

Prairie Mines & Royalty ULC, operating as Westmoreland Coal Company, pleaded guilty this week to one violation of Saskatchewan’s occupational health and safety regulations.

The charge stemmed from an August 2015 incident near Estevan. A worker suffered serious injuries after tripping on a footrest inside the cabin of a dragline excavator and falling about 20 feet.

It was alleged that the company failed to provide and maintain a work environment that reasonably ensured the health, safety and welfare of its workers.

The company was fined $85,714, plus a surcharge of $34,285 in Estevan Provincial Court on Monday.
