There was a article in New Scientist a month or three ago about fires buring in coal seams around the world - it may be available online via http://www.newscientist.co.uk or alternatively, if not there then let me know and I'll scan in the article and mail it to you. The reasons were (I think) accidental ignition, forest fires for open seams on the surface and there may have been one or two more. One thing I've noticed - you mentioed fires in coal tips rather than in coal seams yet everyone seems to be commenting on fires below ground - is this what you meant or do you actually mean fires on tips outside?
