Pike River Mine is located in New Zealand

The Pike River Mine disaster was a coal mining accident that began on 19 November 2010 in the Pike River Mine, 46 kilometres (29 mi) northeast of Greymouth, in the West Coast Region of New Zealand's South Island. A methane explosion occurred in the mine at approximately 3:44 pm (NZDT, UTC+13). At the time of the explosion 31 miners and contractors were present in the mine. Two miners managed to walk from the mine; they were treated for moderate injuries and released from Greymouth Hospital the next day. The remaining 16 miners and 13 contractors, often referred to as the twenty-nine,^[3] were believed to be at least 1,500 metres (4,900 ft) from the mine's entrance.^[4]
