Paper Abstract

An efficient and flameproof system for a quick detection of the concentration of hydrocarbon gases is essential for safety in the underground mine industry. The absence of electromagnetic interference, electrical insulation, easy handling and miniaturization are all the well-known advantages of optical sensors. The optical fiber cables in conjunction with optical sensors are ideal for the use in the explosive and electrically noisy environment of a coal mine. An all-optical methane detection system (OMDS) suited to an underground mine topology is discussed. The optical fiber delivers light to the sensing volume, collects and returns the spectroscopic signal to an on-ground monitoring location. Remote monitoring of methane using the OMDS offers the prospects for improving the safety in the adverse environment of a mine.
