| Summary: | and hydrologic character of the mine site, the conceptual and play a principal role in the rate and degree of oxidation as acid/base accounting have only had limited success. The batch-mixing tests. Results of the analyses led to the been completely identified to date. Therefore, the Gibbons Creek Lignite Mine in Grimes County, Texas was chosen as a data accumulated since 1986. Monitoring results were used to describes the factors which influence spoil water quality. f(RR, SR, AR, OL, SP, SM, ED, RT, SA) where GWQ is the ground factors governed by the fluid medium have the most influence formation of a ground-water quality factorial equation: GWQ = ground-water quality at a surface lignite mine. identify geochemical trends and were coupled with chemical in the lab for both water content and water quality using mineral chemistry. The remaining two factors are the result model proposed can be used to qualitatively predict the modeling of the data using MINTEQA2, an equilibrium of mining activities. Results appear to indicate that the of recharge, AR is the amount of recharge, OL is the of the spoil material. The following four factors are overburden lithology, SP is the spoil permeability, SM is the overburden, RT is available reclamation techniques, and SA is overburden. Preceded by a premine evaluation of the geologic predominant factors which affect spoil water quality have not properties of the spoil medium and primarily control the quality at Gibbons Creek is predominantly controlled by the quality was monitored in two mine blocks and combined with rate of groundwater recharge and the lithology of the speciation model. Mine spoil was also sampled and analyzed spoil mineralogy, ED is the environment of deposition of the system found in mine spoils. Current analytical methods such test site to evaluate the potential factors that can affect The first three factors are controlled by the fluid medium the geochemical evolution of ground water in spoil. Water The prediction Of postmine ground-water quality is encumbered the spoil age. The factorial equation qualitatively upon the evolution of the ground-water quality. Spoil water water quality, RR is the rate of recharge, SR is the source with many complications resulting from the complex hydrologic |
