Investigating the effects of broad ion beam milling to sedimentary organic matter To test if reflectance increases to sedimentary organic matter (vitrinite) caused by broad ion beam (BIB) milling were related to molecular aromatization and condensation, we used Raman and Fourier transform infrared (FTIR) spectroscopies to evaluate potential compositional changes in the same vitrinite locations pre- and post-BIB milling. The same locations also were examined by atomic force microscopy (AFM) to determine topographic changes caused by BIB milling (as expressed by the areal root-mean-square roughness parameter Rq). Samples consisted of four medium volatile bituminous coals. We used a non-aggressive BIB milling approach with conditions of [(5 min, 4 keV, 15°incline, 360° rotation at 25 rpm and 100%...

The organic carbon they contain could be converted to gas using stimulated microbial methanogenesis. In this study, samples were collected from two underground mine sites in the bituminous region of southwest Pennsylvania to assess the potential for these uses from different types of stockpiled coal, including raw coal, clean coal, and refuse coal. Samples were analyzed for coal quality using proximate, ultimate, and sulfur forms analyses, and for major and trace elements. These data complement previous USGS studies on coal waste conducted in Pennsylvania and the Illinois Basin.

Laboratory experiments indicate coal beds can act as natural geobioreactors and produce additional low carbon renewable natural gas with algal or yeast compounds, yet the effectiveness of these nutrients in situ are unknown. This study uses down-well monitoring methods in combination with deuterated water (99.99% D2O) and a 200-liter injection of 0.1% yeast extract to stimulate and isotopically label newly generated methane. A total dissolved gas pressure sensor was placed down-well into the Flowers-Goodale coal bed at the USGS Birney Test Site...

To document and understand the organic petrology and inorganic chemistry of the Leatherwood coal, geologists from the University of Kentucky Center for Applied Energy Research (CAER), Kentucky Geological Survey (KGS), and U.S. Geological Survey (USGS) collected 45 bench samples of the Leatherwood coal in the late-1980’s through the early-2000’s.
