Paper Abstract

Different types of fiber optic methane sensor, especially for ming application, have been reviewed in this paper. Optical absorption and differential optical absorption techniques for the remote detection of methane gas using low-loss silica fiber have been discussed. IR fiber optic, sol-gel and correlation spectroscopy methods have been described in brief. Another noble technique based on attenuation of evanescent field has been enunciated using D- fiber. Merits and demerits of each technique and its suitability to mining industry have been highlighted. Optical fiber, being a dielectric, non-metallic and non- sparking, is an intrinsically safe media and is ideally suited to the hazardous environment present in mines.
