In this paper,a simulation program of hard parcels distributed in a coal seam is set up on the basis of analyses and assumptions,and four distributions of these parcels in a geven coal seam are analysed,which lay the theoretical foudation and necessory conditions of studying cutter random loads and designing dynamically working mechanism and entire machine.
