As part of the Department of Energy's Underground Coal Gasification (UCG) research program, activities at Sandia National Laboratories during FY85 have included laboratory and modeling studies of UCG in Eastern bituminous coals, planning and subsidence studies in support of upcoming Eastern field tests, and post-burn roof stability analyses of the Tono CRIP test. Accomplishments for the year include completion of a preliminary series of laboratory gasification experiments in an Eastern bituminous coal demonstrating that high mechanical strength and low char consumption effects dominate the gasification process in these coals; designing a series of small-scale field tests intended to determine the feasibility of UCG in Eastern coals; evaluating the suitability of proposed field test sites in terms of roof stability/cavity size relationships as a function of overburden strength and thickness; and roof stability calculations (using field measurements as input) for the Tono CRIP test, results of which bracket the observed roof fall. 20 refs., 33 figs., 8 tabs.
