Monitoring and assessment of underground climatic conditions using sensors and GIS tools

Monitoring and assessment of underground climatic conditions are necessary to identify potential hazards and initiate remedial measures in advance that otherwise would lead to disastrous conditions. This paper discusses the concept of real-time monitoring and assessment of climatic conditions in a typical underground mine using sensors and GIS tools by utilizing a laboratory scale model. Typical ventilation parameters including temperature, humidity, and gas concentrations were monitored using sensors in a laboratory setting and various ratios and indices proposed by previous researchers for interpreting fire gases and spontaneous combustion conditions are predicted from the monitored data. GIS tools were used to display this information in real-time on a mine map that would help in creating a safe and comfortable working environment for personnel and equipment working underground.
