Polymeric sealant used to stop shale degradation in coal mines. [8 refs]
Technical Report
·
OSTI ID:7314095
The Bureau of Mines substantially reduced shale degradation in a coal mine by two spray coat applications of a water-base epoxy sealant. More than 12,700 sq ft of passageways were treated, and in 18 months only one failure occurred. This failure was due to improper spray application. Material costs averaged 13 cents/sq ft, and labor costs were 7 cents/sq ft. Labor included moving all materials into the mine, the setup time for each of the areas coated, and application of coatings.
