the short answer is that you cannot. when the whole terrorist thing started up recently, it occured to me that teh most obvious target in terms of damage to for example Victoria, but equally to most coal bearing areas - e.g. India. would be a deliberately started fire. the thing about coal and shale oil is that it will self combust. brown coal is ~60% water. As it dries out, it cools down. if it getrs wet again, the increase in temperature is sufficient to ignite it. As it dries out more, it oxidises... this again increases the temperature. Once ignited, it is difficult to put out, especially once established. Leave a coal seam alight for a week or two and no amount of water will put it out. In Indonesia, once the fire sight is ID'd the way to kill it is to dig out the seam around the fire (big trench - tens of meters deep) and back fill with soil... then wait for the fuel to run out. the recently put out a fire in a NSW black coal mine - pumped in hydraulic expanding cement to seal the burning area off. took a few years to cool down sufficiently to be called 'out'... -- Dr Paul van den Bergen Centre for Advanced Internet Architectures caia.swin.edu.au [EMAIL PROTECTED] IM:bulwynkl2002 It's a book.
