Most Common Types of Mining Equipment in Use in 2023
Surface mining is a mining operation that happens on ground level rather than in a cave.. Statistically, surface mining is more common and efficient than underground mining operations, though the two are vastly different processes. Surface mining operations uncover roughly 97% of all mined materials, primarily due to the flexibility of the surface mining process.

The coal mining life cycle
Underground mining. Some 47% of South Africa's coal is produced from bord-and-pillar mining, stoping and longwall mining, types of underground extraction which access coal up to 300 metres under the ground. Miners travel by lifts down a mine shaft to reach the depths of the mine or enter by means of decline shafts or adits for shallower mines.
