2019-7-5 The Mines Inspectorate expects all underground coal mines to have effective gas monitoring systems with suitably placed methane detectors to prevent explosive accumulations of methane in areas where it could be ignited. Best practices and recommendations to achieve this are outlined in this document for mine operations to consider.
2018-8-1 Coal mine methane gas on-line monitoring system. Methane gas as a safety hazard needs to be managed in a comprehensive manner. For gassy mines, methane drainage is needed which involves drilling holes in the coal seam and pump the methane gas out first before the gas in the coal seam drops down to safe level for coal production.
2012-8-30 Other coal mine chapters deal with methane emission forecasting and predicting the excess gas from troublesome geologic features like faults. Additional coal chapters contain methane controls for shaft sinking and shaft filling, for surface highwall mines, and for coal storage silos. Major coal mine explosion disasters have always involved the

2018-2-28 Methane is a colourless, odourless gas which is trapped in mines as part of the coal formation process. As coal is formed from compressed plant matter methane is produced as a by-product then, when rocks are excavated, methane is released into
2012-11-16 To make coal mines safer, ventilation air systems are now installed, which ventilate the mines at high flow rates, resulting in a Ventilated Air Methane (VAM) stream, with CH4 in concentrations of 0.2-1.2 per cent by volume. This air is then typically vented to the atmosphere.
2021-10-8 The Safety in Mines Research Establishment showed two new detectors at the 1971 Physics Exhibition in London. A reliable device for measuring the methane present in coal mine atmospheres has been developed and also a system for the detection of oxygen deficiency, from which a compact personal alarm has been evolved.

2018-10-3 underground coal mines have historically been given the name “firedamp”, derived from the German word for vapour “dampf”. Its main component is methane, although other hydrocarbons can be present at lower concentrations. Methane is generated when organic material decays in the absence of oxygen. In coal mines, it was produced during the
2.Detection of methane CH4 in coal mine. In coal mine accidents, fire caused by gas explosion and gas combustion accounts for a large proportion, and they often occur together. The main cause of gas explosion is the accumulation of gas in the mine. The main component of gas is methane (CH4), accounting for 83-89%.
2012-8-30 Other coal mine chapters deal with methane emission forecasting and predicting the excess gas from troublesome geologic features like faults.
