This paper outlines a new approach to the measurement of methane concentration in an underground coal mine environment by introducing sequential multipoint fibre optic gas cells connected via a fibre optic cable. An analytical formulation has been developed based on the Beer-Lambert law to determine the average gas concentration in the area where the gas cells are located. The proposed approach will enhance the measurement technique for the gas concentration at any specific location of the mine by improving the accuracy of measurements.
