On Friday evening, the Pike River mine outside the South Island town of Greymouth experienced an explosion which trapped 29 miners below the surface.
The explosion looks to have been due to a methane gas buildup, making rescue attempts difficult, both for fear of setting off a second explosion, and due to potentially high levels of toxic carbon monoxide.
Professor Bruce Hebblewhite, head of the School of Mining Engineering at the University of New South Wales, has been explaining the dangers inherent in an attempts to rescue the men.
