Abstract：

In order to achieve a distributing measure of subsamples in coal heap sampling,the volume(or mass)proportions of the top,middle,bottom of three kinds of coal heaps-taper,wedge,oblong heap are obtained by calculating,and the distributing proportions of subsamples of the top,middle,bottom heap are obtained respectively.The scientific directions of reasonable distributing measure of subsamples in coal heap sampling are offered.
