Kudos to the International Mine Water Association for making the proceedings of the Congresses, Symposia, and Meetings so readily available. At their website you will find the complete proceedings of many of these events, and listings of all. If your interest is in the interaction of water and mines, this is a valuable site. There is an emphasis on acid mine drainage (will anybody, ever find the solution.) In addition, there are many papers on water quality in general as affected by mine workings. I liked the papers on the recovery of groundwater resources once mines had shut down. Best go take a look your self and select the papers that fit your interests.
