    Coal Pillar Design When Considered A Reinforcement Problem

    Jan 01, 2018 Current coal pillar design is the epitome of suspension design. A defined weight of unstable overburden material is estimated, and the dimensions of the pillars left behind are based on holding up that material to a prescribed factor of safety. In principle, this is no different to early roadway roof support design.

    Gasification Plant Design And Operation Considerations

    The most basic consideration is the coal or other carbonaceous feed choice. The obvious considerations such as price, Btu value, sulfur content, ash content, availability and transportation readily come to mind. But there is more to it than that. For example, the ash behavior is critical to the operation of a slagging gasifier.
