Jul 23, 2020· Methane Detection and Monitoring What is the health and safety problem? The use of machine-mounted methane monitors is required by federal regulations to alert miners to the presence of potentially dangerous concentrations of methane while mining coal. The monitors must be permanently mounted on a mining machine to provide continuous readings of methane levels near a working face.
Monitoring Methane Gas Levels. Methane gas monitors feature a non-dispersive infrared (NDIR) sensor.Measurement is based on the physical property that CH 4 molecules absorb infrared light or particular wavelengths. By shining light through the target gas and using suitable optical filters, the light detector will give an output that can be converted into a CH 4 concentration value.
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 the local atmosphere with potential deadly consequences.
Apr 11, 2018· Methane explosions in mines Methane explosions in mines are the result of the concentration of a methane leak in a closed environment. If methane reaches a critical concentration in the air, which is between 5 to 15 % it can react with the oxygen to form carbon dioxide, water and heat. This reaction needs a source of ignition to begin.
Methane gas is flammable and should be monitored in enclosed or underground spaces such as mines and power plants. It also poses the danger of asphyxiation, as it displaces oxygen. Industrial Scientific’s Ventis® Pro Series, Ventis® MX4, and MX6 iBrid® multi-gas detectors, and Radius® BZ1 Area Monitor provide robust, accurate monitoring
In both deep and open cast coal mines methane gas is an ever-present hazard. City’s methane and other flammable gas sensors have extensive approvals to the various global mining specifications. Specific regional issues are a further complication, for example, in South African mines, hydrogen cross-sensitivity is a particular concern.
Firedamp Methane Gas (CH4) Firedamp is a mining term for a set of explosive gases found in mines. It’s mostly made up of methane and methane is often an interchangeable term when miners talk about firedamp. Methane (CH4) is a colourless, odourless, highly flammable, and highly explosive noxious gas.
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 the local atmosphere with potential deadly consequences.
Mar 07, 2018· For gas sensing to be an effective safety measure, the gas sensors used should be able to detect low concentrations of methane gas with high reliability. The Guardian NG for Methane Detection The Guardian NG series from Edinburgh Sensors is one sensor range that is appropriate for the critical safety issue of detecting methane outgassed from mines.
Methane gas is flammable and should be monitored in enclosed or underground spaces such as mines and power plants. It also poses the danger of asphyxiation, as it displaces oxygen.

The reforms, which come into force from January 6, will place tighter controls on methane gas monitoring in Queensland’s underground coal mines. The prevention and early detection of methane related risks are vital to protect workers in Queensland’s nine operating underground coal mines.
5 Although gas detection technology and its use in the prevention of accidents is ever improving, in the past added impetus for change has been provided by several disastrous events in coal mines. 6 Flammable gas detectors do not save lives by themselves, they need to be accompanied by relevant manual and/or automatic control measures that
Methane is known for its tendency to explode, and thus its presence in closed environment puts you at a constant threat. It is known to cause explosions in coal mines, wherein the gas that is trapped beneath the Earth’s crust is released as a result of mining.
According to a U.S. Department of Labor Mine Safety and Health Administration (MSHA) report 1, mining safety has been dramatically improved.Coal mining fatalities alone, tracked from 1900 through 2014, confirm the claim; in 1900, for example, there were 448,581 miners and 1,489 fatalities, while in 2014 the number of miners totaled approximately 120,000, but there were only 16 fatalities.
Sep 01, 2015· Methane gas can appear at explosive levels where it is not typically suspected or during non-routine tasks. To significantly reduce the risk for a methane explosion, it is critical to capture methane, air pressure, and temperature and humidity readings within the mine in near real-time and provide feedback to the mine operation center.
