Underground coal mining methods to abate water pollution: a state of the art literature review. Water pollution control research series
Technical Report
·
OSTI ID:7218225
The report reviews published information concerning the abatement of harmful drainage from underground coal mines. Although much has been written on mine water management, very little literature is available on the specific area of preventing the formation of acid water. The references used in this report include mining engineering and hydrology studies and spans the period of time when water quantity rather than quality was the major consideration. Physical approaches to the problem of interdicting water entry into coal mines, beyond removal and treatment, are (a) land management for surface and sub-surface water diversion, (b) the exploitation of water carrying strata, and (c) new mining methods. Chemical approaches to abatement include (a) the use of silica gel solutions underground to prevent acid formation, (b) the use of inert gas in active mines and (c) the use of new and the refinement of known grouting agents.
