| Abstract: | Based on the principium of picture management,we analyzed the coarse coal picture and characteristic parameter of this picture to extracted some physical features,such as particle form parameter of coal,diameter and gray-scale value using some picture identify software.Quantify analysis of the average diameter connection,average gray-scale value connection,and average form coefficient connection of the corresponding coal particles in the Float-and-sink size fraction experiment of some size levels which were 3~2mm,2~1mm and 1~0.25mm had been done in this paper. |
