September 2012
This month’s very special issue of World Coal is dedicated to opencast mining, the US and, of course, MINExpo INTERNATIONAL 2012. The regional report from Gordon Cope looks at the challenges the US coal sector is facing as the country’s appetite for coal diminishes, and a host of technical articles cover topics including water and dust treatment, fleet management and AC drives for draglines. The September issue also includes a preview of MINExpo 2012 with a profile of the show and its host city, Las Vegas, as well as a directory of the coal-related companies that will be in attendance. Finally, two excellent general interest articles consider the advantages and advances in mine planning and modelling software.
