Abstract A gas monitoring system (description, schematic diagram and specifications are given) was developed and tested for the continuous automatic remote sampling and analysis of coal mine air both in normal and emergency conditions. The main purpose of the system is early detection of spontaneous coal combustion and incipient fires. Air is sampled at multiple locations of the facility (mine, working, etc.) and is pumped via special tubes, which are taped together in looms, to a central surface station, where it is analysed by automatic gas analysers. The system can be used for: routine mine air monitoring for gas (CO and methane) volume; air composition monitoring in isolated mine workings in cases of emergency (underground fires, outbursts of coal and gas); methane level monitoring inside coal bins at concentrating mills, etc. The main limitation of the system is a transport time lag, which may reach 2-3hrs when the sampling point and analyser are 5km apart.
