31 miners were inside the West Coast, Pike River Mine when an explosion occurred on 19 November 2010. Two injured miners managed to walk out of the coal mine.
It’s believed none of the 29 remaining trapped miners survived a second explosion on 24 November.
Two further explosions followed on 26 November and 28 November.
A Royal Commission on Inquiry into the disaster found that the deaths of the 29 miners were entirely preventable.
