1. Introduction. Open cut coal mining is practiced in many parts of the world including Europe South Africa China USA and Australia. Operations are commonly on a massive scale with individual mine pits sometimes exceeding 10 km 2 and 200 m depth. The very significant changes to the landscape and the disturbance of subsurface conditions are not without impacts to the environment
