In preparation, during and also after the mining activities, environmentally relevant issues are examined and concrete proposals for solutions are developed for realisation. Our goal is to minimise negative impacts on nature and the environment and to develop compensation measures at an early stage.

Measures are:

  • Surface and ground water monitoring
  • Processing of mine, process, grey and black water
  • Utilisation of all usable mineral resources (accompanying minerals)
  • Short transport distances
  • Minimisation of dust and noise emissions as well as the space required above ground (processing takes place underground)
  • Creation of compensation areas in the process of forest conversion

After the end of production, the final operating plan is implemented in coordination with the Saxon Mining Authority:

  • Dismantling of all facilities (underground and surface)
  • Cancelling of mine drainage
  • Safekeeping of the accesses to the mine workings according to the planned future use
  • Step-by-step conversion and renaturation of the overburden waste dump, ideally complete dismantling of the dump
  • Continuation of the monitoring programme, in particular for the protected resources water and air, until dismissal from mining supervision


Safety is our highest priority. Mining involves some special circumstances and also dangers. It is therefore important to take appropriate measures, especially to ensure the safety of our employees and the local residents. The basis for ensuring occupational safety in mining is provided by various laws and regulations (e.g. BBergG, ABBergV, KlimaBergV, GesBergV, StrlSchG, StrlSchV). To implement the legal requirements, we work closely with experts in the fields of radiation protection and mine rescue, among others.


What is Radon?

Radon is a natural, colourless and odourless inert gas. It is about seven times heavier than air (1.3 g/l) and therefore the heaviest gas (9.73 g/l). Radon is formed during the radioactive decay of naturally occurring uranium in soils and rocks. All isotopes of radon are unstable, the most common isotope ²²²Rn has a half-life period of 3.8 days.

Where does Radon occur?

Radon occurs in varying concentrations throughout our environment. In the soil, the gas can move through soil pores and cracks in the soil air. Since radon is water-soluble, it can also occur in ground and surface water.

How dangerous is Radon?

Radon can damage the respiratory tract if you are exposed to high concentrations over a long period of time. When radon decays in the lungs, substances are produced that can cause damage to lung tissue. Radon spreads outdoors and dilutes very quickly. However, in rooms without adequate ventilation it can accumulate and become a danger.

Radon and Mining

For radon monitoring, regular control measurements are carried out. We plan to reduce the radon concentration at the workplace to a minimum by targeted ventilation and other technical measures, such as the insulation of radon-contaminated mine areas.
