Mine Atmosphere Monitoring Systems (MAMS) are intended to monitor continuously the mine air at fixed locations in order to detect the presence of contaminants (such as CO or smoke from a fire), the levels of methane and oxygen, and the velocity of airflow. Further, MAMS are intended to alert mine personnel of a potentially hazardous situation in a time frame sufficient to safely evacuate personnel and/or initiate and execute proper corrective procedures. MAMS are intended to augment, not to replace, conventional methods for underground hazard protection, thus increasing the level of safety in underground mines. In order to perform their intended functions, MAMS must be highly reliable and designed properly. Reliability is a function of the electronic components that are used to fabricate the system and subsequent calibration and maintenance of these components. In general, reliability of MAMS is independent of the mines in which they are installed and used. Design, on the other hand, can be very dependent upon the mine in which the system is to be used. Proper design of MAMS include the selection of appropriate monitoring locations and placement of transducers which can depend upon the layout of an underground mine. It is the intent of this paper to discuss both the reliability and design aspects of MAMS in order to provide better understanding of these systems, their capabilities, and their limitations. Particular emphasis will be placed upon the use of these systems for automatic fire detection.
