Abstract:

Methane is one of the potentially dangers in the coal mines. Some human damages happend due to methane explosion in the world every year. Hence, the ventilation is one of the most important operations in the gassy coal mines. Some styles named methane drainage techniques have been established in the recent decades. These techniques are used for preparing the required fuel for industries and decreasing the concentration of methane in the mine atmosphere. Methane drainage is carried out by some techniques as: Horizontal borehole degas system, vertical gob degas system, cross measures methane drainage system and so on. Several instruments like pump, pipeline and control appliances are necessary for degasing in the coal mines. In accordance with the achieved conclusions in this article, the methane drainage is not necessary up to 800m depth in Kerman coal mines. Therefore, it is possible to dilute the methane gas up to TLV by correct ventilation.
