云南大河中深部9号煤层位于含煤地层中上部，为滇东分布最广、厚度最大的主要可采煤层。区内该煤层层位稳定，煤层倾斜平缓，煤层埋深在中部深，边缘浅，煤层平均厚度3.50 m。主要由焦煤、1/3焦煤和少数肥煤组成，此类煤一般具有生气率高、吸附量高（大于15 m3/t）、可解吸率高（大于70%）的三高特点，有利于煤层气的富集高产。研究该区特征，对于类似区煤层气勘探具有重要指导意义。

No. 9 coal seam of Yunnan Dahe Mine is located in the upper part of the coal bearing strata,is the most widely distributed and the thickest minable coal seam.The coal seam is charactered by stable position,gentle incline ,bearing in the middle-deep part, shallow edge,3.50 meters deep average. The coal seam is made up of coking coal,1/3 coking coal and a small amount of fat coal,the coal has high gas generating rate,high adsorption rate(greater than 15 m3/t)and high desorption rate(more than 70%),those sre favor-able to the enrichment and high yield of coalbed methane. Study on the characteristics of this region is of great guiding significance for similar exploration of coalbed methane.
