SOUTH AFRICAN COAL SECTOR REPORT - Energy

2018-5-25  There are three different mining methods that are commonly used in underground mines in 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
