	In abandoned mines methane is still set free. In many area the overburden is fraced and the gas escapes to the atmosphare. To improve the safety old connection between the underground tunnels and the surface are used to vent the gas. In most cases the underground areas of the abandoned mine are connected. So the gas from a big area can exhaust by one borehole.		In abandoned mines methane is still set free. In many area the overburden is fraced and the gas escapes to the atmosphare.
