Gases found in the Coal Mines The danger from explosions is ever present in coal mines. Ignition of naturally occurring methane gas can be disastrous. This gas is known in the pits as firedamp, a mixture of methane gas and air. Methane (CH4) is odorless, tasteless, colorless, and lighter than air which means it is found near the roof of the .
Coal Mine Detection Robot uses infra-red spectrum absorption way to detect methane, carbon monoxide and such gas simultaneously. The principle of gas survey meter of infra-red spectrum is according to the selectively absorption of infrared radiation by the mash gas, CO to achieve the detection of their concentration.
Abstract - In coal mines there square measure such a big amount of venturous gases that square measure gift displaces the mandatory gas to support the human life, so it's necessary to develop such a technology to live the extent of the harmful gases therein atmosphere that facilitate U.S.A. to save lots of

Electrochemical gas sensors are gas detectors that amount the concentration of a target gas by reacting or reducing the target gas at an electrode and measuring the resultant current.An alarm gives.
The presence of combustible gases is the main gas risk faced by miners in their daily work. Methane gas explosions in underground coal mines remain a serious risk which requires comprehensive monitoring. Owing to its understanding of mining, MSA has equipped the ALTAIR 4X detector with a methane-optimised XCell EX-M sensor.
methods for detecting above gases are given in T able II and their operating principles are summarized in Table III. Table II : Different methods of gas detection
