Mine Environment Monitoring System And Sensor Performance Evaluations

The paper describes the capabilities of a micro-computer-based real time data acquisition system for monitoring and control of mine environments. Applications of such a system for monitoring the ventilation and air quality of a mine is outlined. The paper discusses the results of running a monitoring system with various environmental sensors in a simulated mine environment. The sensors used in this study are: carbon monoxide (CO), carbon dioxide (C02), nitric oxide (NO), nitrogen dioxide (NO2), sulphur dioxide (SO2 ), methane (CH4 ), air flow, absolute pressure, temperature and relative humidity. A performance evaluation of the monitoring system and sensors is presented.
