A third explosion yesterday rocked a New Zealand mine where 29 workers perished in an earlier blast, authorities said.
Emergency services teams were at the mine site when the 20-second explosion occurred, but no one was injured, New Zealand Police said in a statement.
"This will not impede the recovery work we are doing at the site and we are continuing with our forward planning as scheduled," said Gary Knowles, superintendent of Tasman Police.
The explosion occurred a week after the first blast at the coal mine left 29 workers trapped inside.u00a0 Authorities said dangerous gas levels in the mine were too high for rescuers to enter.
