The main mineable coal seams (Nos.2 and 9+10) in the Checheng general exploration area, Jixian County, Hedong coalfield possesses of coal resources 1.44 872 billion tons. In which, the coal No.2 is medium ash, low sulfur, medium high calorific value and high ash softening temperature meager coal and anthracite;the coal No.9+10 is medium ash, medium high sulfur and medium to high ash softening temperature meager coal and anthracite. Based on sorting and analysis of tested data from 15 boreholes in the exploration area, according to coal resources cleanliness 6 grade partition scheme proposed by Tang Yuegang et al have carried out main mineable coal seams cleanliness assessment. The result has shown that cleanliness of coal No.2 is from categories II to VI, and mainly category III better clean coal and category VI medium clean coal, thus belongs to medium better clean coal mainly distributed in middle and northwest parts of the exploration area;coal No.9+10 is from categories IV to VI, mainly category IV medium clean coal, belongs to me?dium clean coal distributed in vast majority of the exploration area.
