RAG secures old manholes The consequences of hard coal mining include old mining, mining damage and the land intended for conversion on which mining was previously carried out. The topic of old mining is of great importance in North Rhine-Westphalia alone due to the high number of around 60,000 old daily openings, shafts and tunnels. But not all pits are in the area of responsibility of the RAG. The company is currently responsible for an area of around 30,000 hectares with surface and near-day quarrying as well as around 7,400 old daily openings. These locations were localized with the latest technology, secured if necessary and transferred to a monitoring system. In addition to the security measures, there is an active search for areas at risk of daybreak and - if necessary - their renovation. The old RAG shafts are mapped and are regularly driven in accordance with the specifications of a certified management system. Which day opening needs to be rehabilitated depends crucially on what is in its hazardous area. The consequences of old mining in the vicinity of schools, public buildings and children's playgrounds have high priority. Former shafts in forest areas are fenced off and marked with hazard signs. © RAG Aktiengesellschaft 2021 data protectionLegal noticeimprint
