Abstract
This report describes the laboratory tests to determine a suitably stable foam, methods of emplacing the foam in coal, and a comparison of the effectiveness of foam and water for blocking the flow of gas through coal. It concludes that unstable foams are more effective than water in blocking the flow of methane but points out possible difficulties with the use of the technique underground.
