Methane can escape as mine gas from areas around old shafts at abandoned mines and create a hazard at the surface. Intelligent planning for the areas around such shafts makes it possible to neutralise any danger at the surface.

DMT designs customised combinations of gas drainage measures to evacuate any rising mine gas safely. Once our engineers have assessed the situation and, if necessary, have implemented measures to improve stability, it will generally be possible to build on such properties without any restrictions.
