『Abstract
　To classify mine environmental geology problems, three schemes are advanced. The first one, according to mine type, is relatively particular but with some problems repeated across mine types. The second one, according to the developmental stage of the mines, describes different problems in the whole development and evolvement history of mines, however it is still large scale and simplistic. The third one, based on the characteristics of the geological problems existing in the mines, is more easily applied. The third scheme can also be used to analyze the characteristics of different types of mine environmental geology problems.

Keywords: Mine environmental geology problems; Classification; Mine type; Mine development』
