Protection of the environment

Methane represents a considerable danger in abandoned mines. Methane (CH4), set free from coal, gets to the surface by migration. It can get to surface pits and tunnel systems or other comparable cavities. In connection with air, methane can produce inflammable and explosive mixtures. There is special danger if the methane gas migrates from the cavities or directly from the soil in the existing drains systems. The safety risk is not calculable. Likewise methane can be set free when building work is done. Thus setting free methane moves into the center of environmental questions when speaking about danger warning and planned projects.
