January 2014

In this month’s issue of World Coal, the regional report focuses on India, where Ng Weng Hoong provides a detailed insight into the scandal-prone coal industry. World Coal looks at conveyor engineering and design, as Richard Shields and Daniel Marshall, Martin Engineering, US, chart an investigation into conveyor belt cleaning practices at a Powder River Basin coal mine. We also feature articles on conveyor drives and mining trucks, with a series of articles also focusing on concentration and dewatering. The Industry View from Dr Lars Shernikau, IchorCoal and HMS Bergbau, presents an outlook for 2014 as the coal industry looks to move on from 2013, which was, as Dr Shernikau explains, a somewhat “disappointing” year for the global coal industry.
