Abstract：Because that the Santanghu coalfield has rich coal resources,and the exploration degree is high,this paper introduced the geological circumstances and coal resources(19.639 billion t)of main workable coal seam(No.9 coal seam),and combining with the contour maps of coal ash and volatile matter,the main coal quality indicators of No.9 coal seam were researched.The research of results showed that: the main coal type of No.9 coal seam is the extra low moisture content coal,part of the coal is low moisture content coal and medium moisture content coal;according to the 535 testing data from Shitoumei,Hanshuiquan,Kumusu and Tiaohu mining areas,we could see that the main coal type of No.9 coal seam is the low ash coal,secondly,is the extra low ash coal,part of the coal in Hanshuiquan and Kumusu is the medium ash coal;according to testing results from the 559 drills,we could see that the main coal type of No.9 coal seam is the high volatile matter coal,secondly,is the medium-high volatile matter coal,in the most part of Kumusu area,part of Hanshuiquan and Tiaohu area,there exists the extra high volatile matter coal;at west area(Hanshuiquan area)and middle area(Shitoumei area),the extra low sulfur coal and low sulfur coal distributes equally,at individual area,the medium sulfur coal exists,but in the Kumusu and Tiaohu area,the main coal type is the extra low sulfur coal,that is to say,the main coal type of No.9 coal seam is extra low sulfur coal,secondly,is the low sulfur coal;the major part of the coal is high calorific value coal,the medium-high calorific value follows secondly,at part of the Shitoumei area,there exists the extra high calorific value coal,at part of the Kumusu area,the medium calorific value coal exists.Therefore,the coal from No.9 coal seam is the good thermal coal,gasification coal and industrial boiler coal.But the indicators varied at different mining areas,so for industrial application,how the variation of coal quality indicators affects the equipment and the utilization efficiency should be noticed.
