SOUTH AFRICAN COAL SECTOR REPORT Energy

South Africa. The most common technique is the ‘bord and pillar’ method, which accounts for just under half of total coal production (SACRM, 2011). This method is ideal for relatively shallow deposits where overlying rock pressure is low. Seams are mined leaving in situ coal pillars, which are big enough to support the roof indefinitely.

Bord-and-pillar mining in inclined orebodies

The UG2 reef was chosen for bord-and-pillar application due to its higher reef width, which implies less dilution. There are two current bord-and-pillar projects at Amandelbult, 16 West and 43 East. This project is aimed to design a bord-and-pillar layout section for

In South Africa, coal was first mined on a commercial basis in 1857 and South Africa is currently the 6th largest producer of coal worldwide. The two types of underground coal mining are the conventional mining system and continuous mining system. Continuous mining is the most common form of underground coal mining method and

The coal mining life cycle Mining for schools

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.

Can bord and pillar fly in Australia? MiningMonthly

Oct 13, 2006 THE bord and pillar method is widely used for coal production in South Africa and has developed in efficiency and productivity in recent years. Mining Consultancy Services managing director of Australia Chris Wilkinson says a review of underground mining practices could find bord and pillar conducive to Australian conditions.
