Approximately 51% of South African coal mining is done underground and about 49% is produced by open-cast techniques.
SOUTH AFRICA’S COAL INDUSTRY OVERVIEW, 2014
Both opencast and underground mining methods are employed in South Africa for extraction of coal reserves. 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. This method is ideal for relatively shallow deposits
