The vast majority of underground coal mines in the United States are relatively small operations. Of the 1,345 U.S. underground coal mines in operation durhg 1992, about one-half (638) employed 20 or fewer people and about one-third (454) employed between 20 and 50 people. The median number of employees was 22. Mines of fewer
Present systems for fire detection in industrial coal pulverizers use either thermocouples to measure the rise in outlet temperature of the pulverizing mill or infrared gas analyzers to detect the buildup of CO produced in the mill. Thermocouples or RTD's are normally part of the control system for mill operation.
