Establishment and maintenance of a coal sample bank and data base
In the project status report for 4/9/90--7/8/90, Table 2 presented update results of a comparative study of coal sample deterioration in several container types including foil laminate bags. This table contained an erroneous entry (foil laminate bag {minus}20 mesh, alkali extraction 65.4% transmittance). The alkali extraction test on {minus}20 mesh coal stored in foil laminate bags for 52 weeks was repeated in duplicate on another bag (after 64 weeks total storage) resulting in a measurement of 96.2% transmittance. This value has been substituted for the erroneous 65.4% value in the corrected copy of Table 2 enclosed with this report. All values of the alkali extraction and Gieseler fluidity tests indicate that the state of preservation of sample in foil laminate bags is excellent. The samples stored by other methods for comparison purposes all showed significant loss in fluid characteristics. One new whole-seam channel sample of the hvAb Pittsburgh seam coal, DECS-12, was collected July 25, 1990 in Greene County, PA. This sample was placed in 30-gallon steel barrels with high-density lid gaskets and purged with argon at the mine. Upon return to Penn State it was promptly processed so that Gieseler fluidity and other routine analyses could be performed.
