The impact of different mining techniques on the geothermal potential of abandoned coal mines
Abandoned and flooded coal mines have a huge geothermal potential. By circulating mine water and extracting its heat, it can provide a renewable, low-carbon low-enthalpy heat source for domestic and industrial purposes. But capital costs from drilling into those mine workings are significant, and investigating the geothermal potential of a mine system ...Jeroen van Hunen +3 more

Coal Winning From Abandoned Mines or Outcrops
2001This study covers the results of a literature survey about methods developed or techniques currently applied to win the coal left from underground and surface mines. Coal extraction has generally been done by augering, but mechanised excavation systems that utilise continuous miners have been developed for higher productivity.

The mobility of metals in acid mine drainage from abandoned coal mines
2023The acid mine-drainage contaminated Blesbokspruit catchment west of Witbank in Mpumalanga province, South Africa has been investigated, by analysis of its waters, sediments, precipitates and algae, to obtain an understanding of the processes which control the mobility of metals in these waters. The Blesbokspruit drains acid mine drainage originating in

Heat storage in abandoned coal mine shafts in Scotland
Following an increase in demand and extent of renewable energy systems, one of the most urgent challenges in the energy transition is the storage of intermittent renewable energy. Storage would enable continuous energy supply and ease current difficulties in balancing the energy grid.Jessica Dassow +11 more
