coal reclaim tunnel ventilation design

  • How to design and improve stacking and reclaiming systems

    Rail-mounted stacker/tunnel reclaimers, which can build longitudinal piles over tunnels, offer high availability and require minimal operating personnel but have disadvantages of limited live storage and high cost of slot storage. Combination bucket wheel stackers/reclaimers are the most commonly used in coal yards.

  • Guidelines MDG 28: Safety requirements for coal stockpiles

    The coal stockpiles referred to in this guideline are of a size that require stockpile dozers to be used to facilitate handling requirements. In most cases these coal stockpiles are over a reclaiming tunnel. Coal stockpiles are either run of mine or washed product stockpiles created from the coal mining and coal washing processes. 1.4.4 Dozer

  • GUIDE FOR TUNNELLING WORK
