Methane (CH4) is an odourless, flammable, and colorless gas, and a chief constituent of natural gas. It is a powerful greenhouse gas, which can be obtained naturally or can be a result of human acts such as agriculture and fossil fuel production. It has a short lifespan and is the simplest member of the paraffin series of hydrocarbons. The rate of methane production depends on many factors such as amount of rainfall penetrating through organic matter, the temperature and the type of organic substances. It is also known as marsh gas because it is produced by anaerobic decomposition of plants and other organic matter. In natural process / geological processes, methane and coal are formed together. During the coal mining, the methane gas is released into atmosphere. In underground mining, it is released in to the mines; in surface mining it is released directly into the atmosphere; in post-mining activities, it is released during subsequent process and in abandoned mines, it is present as unascertained and released at unknown rate. The environmentalists and researchers have always attached a great significance to the presence of this gas. This is a hazardous and unavoidable gas emitted during mining process.

Ÿ The Tragedies that could have been Prevented, if methane gas detector had been used : Ÿ On 9 November 1963, an explosion at the Miike coal mine in Japan that killed 20 miners and 438 more died

afterwards from carbon monoxide poisoning. Ÿ The worst disaster, that occurred on 26 April 1942, in the Benxihu Colliery in China, which killed 1,549

miners. Ÿ Methane explosion in the Russian coal mine, of Ulyanovskaya at Kemerovo Oblast, where 108 died on 19

March 2007.
