NTIS: PB 250 603 Available for Reference At Bureau Libraries :85 pages
The objective of this contract was to develop and test in a working mine gas sampling systems for remote sampling of air at the working face for use with approved portable methane detectors and machine- mounted monitors. A portable unit with an 18-foot reach for use with methanometers and an hydraulically powered machine unit with three sample ports for use with methane monitors were designed and built. Both units were tested at Bethlehem Steel's No. 58 Mine at Marianna, Pennsylvania.
