Abstract：The general situation of Pingshan coalfield in Guizhou province was expounded, according to the physical properties of coal, coal lithotypes and the degree of coal metamorphism, the coal quality characteristics and variable rules of workable coal seams were analyzed systematically.The relationship between the sedimentary environment and the content of ash and sulfur etc. were discussed.The sulfur content of coal decreased gradually from southeast to northwest and was band distributed irregularly, its using aspects was put forward primarily in this paper.
