Risks and challenges affecting opencast pillar mining in
During the early years of coal mining, over 90% of South Africa's coal was produced by underground bord and pillar mining (Mohutsiwa and Musingwini, 2015). However, one of the biggest disadvantages of this method is its relatively low extraction ratio - an average of just less than 50% across all collieries in South Africa (Madden et al., 1995).
