http://news.bbc.co.uk/2/hi/europe/6469339.stm The killed Briton was a bank representative. Poor man. This evening I fly to Kemerovo (local regional centre) and will be on another (nearby) coal mine. Now I supervise a project of industrial automation of coal processing plant. So I will ask the locals what really happened. Who installed metan detection sensors and controllers? Who checked them? Likely British experts at least took part in this process. Why this terrible disaster has happened. Now I haven't any idea. Let's say RIP to all victims.
