Abstract :
The mining industry requires a reliable system to accurately and safely measure methane concentrations at various locations in underground coal mines. This paper aims to investigate the potential for an all-fibre optic based methane sensor. Various types of all-fibre sensors are studied and side drilled hollow core fibres have been experimentally tested. The results show that hollow core fibre has the potential to be developed as a methane sensor and implemented in an underground coal mine environment to accurately and safely measure methane concentrations with acceptable response time and accuracy.
