Improvements in coal mine gas detection instrumentation.
Proc 2nd Symp on Underground Mining NCA/BCR Coal Conf & Expo III, Louisville, KY, 1976 Oct; :206-216
The gas detector sensor research program directly supports the fire and explosion prevention and industrial hygiene programs of the Bureau of Mines. The work is concentrated on development of new sensors and prototype instrumentation for detecting combustible and toxic gases. Specifically, the primary gases of concern are methane, carbon monoxide, nitrogen dioxide, nitric oxide, oxygen, and carbon dioxide. The ultimate objective is to develop transducers of suitable size, specificity, short- and long-term stability, and power consumption, primarily for use in small personal gas detection devices such as handheld indicating detectors or personal dosimeters or alarms. For each gas, recent accomplishments and status of the research are discussed. Of particular interest are the new developments of a CO detector and a methane monitor. Research and new developments in anemometry are also presented.
