Opencast coal mining is strongly resisted in the "desolate North", an area that has become a sace zone for continued economic growth at the cost of the global climate, local environment and community health. The region supplies the UK''s dirty power stations, leading CO2 emitters, while people in the global South are suffering the consequences.
The process of ore exploitation in opencast coal mining is complex and demands hiring many people and providing varied equipment. In order to provide continuous (twentyfour hours a day) production and to excavate the planned amount of ore and overburden in an opencast coal mine, it is necessary to achieve optimal working conditions.
