The geologic character of some coal wants at the Westland Mine in southwestern Pennsylvania. Report of investigations/1981

Technical Report ·
OSTI ID:5837024

The coal wants at the Westland Mine in southwestern Pennsylvania consists chiefly of elongated, sandstone filled channels with slickensided basal contacts. Tentatively identified as washouts, these channels are about 1,000 feet long and 300 feet wide, are erratic in occurrence and trend, and are difficult to delineate from the customary core drilling pattern. Roof conditions are hazardous adjacent to the washout contact, but roof stability is generally unaffected greater than 30 feet away.
