In 1995 and 2003, the U.S. Mine Safety and Health Administration (MSHA) conducted surveys to determine the number of atmospheric monitoring systems (AMS) that were being used in underground coal mines in the United States. The survey reports gave data for the different AMS manufacturers, the different types of equipment monitored, and the different types of gas sensors and their locations. Since the last survey in 2003, MSHA has changed the regulation requirements for early fire detection along belt haulage entries. As of Dec. 31, 2009, point-type heat sensors are prohibited for use for an early fire detection system. Instead, carbon monoxide (CO) sensors are now required. This report presents results from a new survey and examines how the regulation changes have had an impact on the use of CO sensors in underground coal mines in the United States. The locations and parameters monitored by AMS and CO systems are also discussed.
1995年和2003年，美国矿山安全与健康管理局（MSHA）开展了调查，以确定美国地下煤矿中正在使用的大气监测系统（AMS）的数量。调查报告给出了不同AMS制造商的数据、所监测的不同类型设备的数据，以及不同类型气体传感器及其位置的数据。自2003年上次调查以来，MSHA已更改了沿皮带运输巷道进行早期火灾探测的监管要求。截至2009年12月31日，点型热传感器被禁止用于早期火灾探测系统。取而代之的是，现在要求使用一氧化碳（CO）传感器。本报告展示了一项新调查的结果，并探讨了监管变化如何对美国地下煤矿中CO传感器的使用产生影响。还讨论了AMS和CO系统所监测的位置和参数。
