The aim of this course is to provide participants with a comprehensive understanding of the factors that influence the design of a longwall mine. As a result of attending this course, participants will have a greater understanding of how the major design decisions for a longwall mine are made, be able to optimise the mine layout and make better decisions in the analysis of a
