| Abstract |
The report presents detailed results of a feasibility study of down-dip mining, a technique that appears to offer an alternative to sealing or permanent treatment of polluted effluents from coal mines after abandonment. The project included an evaluation of a pair of nearly identical abandoned underground mines - one developed to rise, one developed to dip - to confirm the theory that discharge water quality in down-dip mines is substantially better than that in up-dip mines. An active mine with units operating up-dip and down-dip was also evaluated to ascertain economic and engineering limitations, costs in varying situations, and other major advantages or disadvantages of each mode of operation. Health and safety and National water quality and economic impacts of widespread use versus non-use of the technique were also assessed. |
