−−−The geology of the Paparoa Ranges was notorious. Pike River is just 20km from the Brunner mine, where 65 died in 1896, and had the same gas issues, which the company was well aware of and had highlighted to investors in the week before the explosion.
Mr Morris said it probably only needed a cubic metre of methane and a spark to go off to have a devastating effect.
"But with the money they have spent developing that mine, it is just hard to comprehend that they have overlooked something about the ventilation, it's very hard to accept." (中略)
Pike River had haunting similarities to Strongman in 1967, he said. (以下略)

NZで多数の犠牲者を出した炭鉱事故は上掲の如く殆どが爆発によるもの、かつ同じ "Paparoa Ranges (連山・山脈)" に位置する炭鉱では過去にも同様の事故が起こっていますから、ガス対策が然るべく講じられていたのかが問題となりそう。
