The gas monitoring system in an underground coal mine is an integral part in creating a safe work environment for the coal mine workers. The gas monitoring system provides feedback on the effectiveness of the ventilation system, gas drainage system, seal integrity of goafs and gas make on the active face/development panel. The aim of this paper is to provide a number of examples, where possible improvements can be made to Tube Bundle monitoring systems. Two of the Tube Bundle systems biggest limitations are slow response times to changing gas conditions underground and the high cost of tube installation underground. This paper will discuss two possible step change improvements with the aim to address these limitations to make the Tube Bundle system more responsive and provide greater coverage underground for lower cost outlay. This paper will also explore the use of automation to reduce the cost of Tube Bundle system maintenance while improving reliability.
