Anthracite mine flushing projects in Scranton Pennsylvania
Testing new methods of flushing. The second method of flushing used in the early flushing projects was called "controlled flushing". In this method a smaller number of boreholes would be drilled. Old mine openings would be reopened so that workers could enter the old mine workings. Or if none were available, a 42 inch borehole would be drilled.get price
