  • Opencast mining Enefit

    In places where the oil shale stratum is not very deep below the surface, oil shale is mined in quarries, which can extract oil shale from depths of up to 30 metres. It is possible to use more powerful and larger mining machines in opencast mining, making it much more efficient than underground mining.
