Abstract: In-situ gasification can be competitive with shaft mining for the exploitation of coal at depths too deep for surface mining. The lignite deposits in Texas may be well suited to this process ...

Abstract: This paper summarizes a set of high priority basic engineering research needs in the field of Process and Systems Dynamics and Control which are important to the development of future energy ...

Abstract: Tests have been carried out to quantify the variation in permeability of Texas lignite with drying and with applied stress. It has been shown that the matrix permeability of lignite may be ...
