Modelling of strata movement with a special reference to caving mechanism in thick seam coal mining

International Journal of Coal Geology, 2006
Caving of top coal behind the face is the key factor affecting the efficiency of production at thick coal seams. During production of top coal by caving behind the face not only is a significant amount of coal lost in the goaf but also the coal drawn by ...
