METHODOlOGY FOR THE CHARACTERIZATION OF ANTHRACITE REFUSE
Special Research Report SR-86 Large quantities of ground-water may be encountered in deep coal mines which must be treated to meet water-quality standards before being discharged. Source beds supplying leakage to deep mines may be dewatered during and after mining under favorable hydrogeologic condi- tions to prevent pollution, thereby minimizing treatment costs and improving working conditions, Requisite hydrologeologic data to deter- mine the feasibility of dewatering may be obtained during the coal exploration program provided that both hydrogeologic and coal explora- tion programs are planned in advance and coordinated, Hydrogeologic data required include the spatial distribution, thickness, and geometry of aquifer and non-aquifer units; hydraulic boundaries that either restrict the flow of ground-water, stratigraphic pinchouts, fault offsets, erosional unconformities, or serve as recharge sources, channel sandstones, flooded deep mines, fractured roofrock etc,; permeability and storage distribution; infiltration capacity of streambed sediments; vertical permeability of confining beds; and hydraulic heads among and between various aquifer and non-aquifer units, The search for an effective means of disposing of approximately one billion tons of anthracite coal refuse has been immensely hindered by the lack of information pertaining to the characteristics of the material and the absence of methodology capable- of determining these characteris- tics. In the past, investigation of the material's compositional properties was essentially impossible, as the intimate association of organic and inorganic constituents made standard techniques of composi- tional analysis such as x-ray diffraction, infrared spectroscopy, and microscopy ineffective. Complete separation of the organic from the inorganic without destruction or alteration of the minerals present has previously been unsuccessful.
