Nick Wills, Director/Principal Consultant, from Australian Longwall Consultants delivered this presentation at 2012 Longwall conference in the Hunter Valley Australia. Building on eleven years of excellence it’s rare that such a large gathering of underground coal operators come together under the one roof, providing a great opportunity to catch up with friends, industry leaders, former colleagues and longwall mining specialists.
