- W4205387488 abstract "During the report period, channel and block samples of the Pittsburgh seam (DECS-23) were collected from Consolidation Coal Company`s Bailey Mine and were subsequently processed and partly analyzed. Powdered vitrinite concentrates were prepared from the block samples in a nitrogen-filled glovebox, and small coal blocks containing {approximately}5 mm thick vitrain bands were cut from the larger sections. Results of proximate, ultimate and petrographic analyses showed that the concentrate contained 97% (by volume, dmmf) vitrinite and about 3% (by weight) pyrite. On the basis of fluorescence intensity and alteration measurements, the coal and concentrate appeared to be extremely fresh, exhibiting no signs of oxidation or deterioration. A polished surface of one of the small coal blocks was prepared and photo-oxidized in order to evaluate reflectance-mode FTIR equipment and techniques, as well as for the measurement of contact angles. Photo-oxidation of this sample was accomplished by blue-light irradiation. In addition, arrangements are being made for the collection of two Lower Kittanning seam coal samples (marine- and freshwater-influenced) from northwestern Pennsylvania." @default.
