so why not put a link to a webbie for this incident?
Anyway after looking at this thread,i went to look for the news of this incident and it says that the 13 initially survived.Maybe this early news that they survive initially was actually the news leaked out to the family but the authorities at that time did not knew they were dead already?
"Most of the 13 coal miners trapped in an explosion apparently survived the blast itself, retreated deeper into the mine"(quote from a article)
