 · The power required for crushing the coal gangue from a particle size of 300 mm to 25 mm was much lower than that required for crushing the coal gangue to a particle size below 2 mm. The second reason for the size of the gangue is that an artificial separating wall, which is an important backfilling process, can relatively easily contain slurries containing larger particles. The purpose of ...

A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Although coal beds are usually considered as discontinuous media, the main purpose of this study is to reveal the fracture mechanism of coal with gangue under the impact of a water jet. Therefore, in this study, we assume that coal contains only gangue and random defects, where the random defects could reflect the discontinuity of coal to a certain extent.
