Abstract
The objective of this investigation was to develop a hand-held device to remotely detect the presence of concentrations of methane gas in underground coal mines. Convenient "mapping" of methane from a remote location would allow rapid and safe corrective procedures for working personnel. Modified, commercially available equipment was evaluated both in the laboratory and in a working mine. Although readings were obtained and the general principle of operation demonstrated, the power levels necessary and the protective enclosures required would raise the weight of the instrument beyond practical limits of portability. Based on currently available technology, it was concluded that a practical, portable, hand-held visual methane indicator is beyond the state of the art.
