Underground coal mining methods to abate water pollution
1970
Wilson, Larry W. | Matthews, Noah J. | Stump, James L.
The report is a review of published information pertaining to the abatement of harmful drainage from underground coal mines. Reviewed are new physical approaches to the problem of interdicting water entry into coal mines. These include land management for surface and sub-surface water diversion, the exploitation of water carrying strata, and new mining methods. Some chemical approaches to abatement reviewed include the use of silica gel solutions underground to prevent acid formation, the use of inert gas in active mines, and the use of new and the refinement of known grouting agents.
