As much as 4.7 billion tons of an estimated 23.5 billion tons of near surface mineable lignite in Texas lies beneath modern alluvial valley sediments. The shallow groundwater table, flooding, acid water production, and prime agricultural usage will make the floodplain very difficult to mine by conventional surface mining methods. Application of well developed hydraulic dredging techniques to lignite recovery in alluvial valleys may represent an increase in mining economy and a decrease in adverse environmental effects. It is envisioned that a small, portable dredge will utilize the existing hydrologic conditions to mine the floodplain as a supplement to major surface mining operations, and provide an additional 4.7 billion tons of lignite for use. 4 refs.
