Magatar Mining uses a similar continuous miner equipment set to that utilised in bord-and-pillar underground mining, but changes the way the equipment is assembled, operated and sequenced. While there has been a lot of interest in South Africa, mining companies are often reluctant to be the first to try a new technology.

Mienie has experience as a bord and pillar mining manager and has worked in underground mines in South Africa, New Zealand and Australia. Foulstone was appointed at a time of rapid expansion and ramp-up at Cook Colliery.
The study uses data from completed coal mining projects from selected coal-producing countries. Three formulae are developed and presented for estimating capital costs of underground bord and pillar, surface shovel and truck, and dragline operations. Keywords coal mining, capital costs, parametric cost estimation. * Standard Bank of South ...
indicates that pillar extraction is a possibility, which can significantly increase extraction factors – although this is a topic for further investigation. Magatar Mining carried out extensive simulation exercises in South Africa with a comparative underground bord-and-pillar panel and claims the following improvements:
Prepared the study tender, participated in award activities, fulfilled role of Acting Project Manager during kick-off, assembled project team and appointed key contractors for a greenfields underground bord and pillar coal mine for in South Africa (production capacity - 11 mill. tonnes PA).
Feb 27, 2016· INTRODUCTION In India, about 98% of underground output of coal is obtained by Bord and Pillar method and barely about 2% by longwall methods. The other countries where Bord and Pillar method predominates are Australia, The USA and South Africa. The key to the successful Bord and Pillar mining is selecting the optimum pillar size.
(Longwall mining of coal is discussed in greater detail in coal mining: Underground mining.) In hard rocks, such as the gold- and platinum-bearing reefs of South Africa, the same basic pattern is followed, but in these cases the seam is removed by drilling and blasting, and the ore is scraped along the face to a collection point. Roof support ...

The Vele colliery project is located on the northern border of South Africa's Limpopo province. The mine spreads across ten farms with 8,663ha of land. It is owned by Limpopo Coal Company, in which Coal Africa Limited (CoAL) holds 80% of Limpopo Coal's shares.
Based on current mining cost parameters, approximately 30% of the Mmamabula coal resource could be extracted economically by open cut mining methods and underground bord and pillar mining methods using conventional continuous miners is being planned for the remaining 70%.
