CHAPTER 3 Coal Preparation and Cleaning
determine whether coal is supplied to a preparation plant wet or dry and in large lumps or small particles. Whereas surface mining and conventional underground mining methods generally produce coarse, comparatively dry solids, continuous mining machines employed in many underground mines produce fine-size solids which are wetted for dust control.
