Abstract: The mining field is situated in the joint part of Neihuang bulge and Dongming hollow of north China depression, and belongs to Kaifeng coal-forming district. The coal-bearing strata is Permo-carboniferous, including 13 coal-bearing layers, among which 5 are minable; 2₁ coal layer is the primary minable coalbed, 2₀², 1₄², 1₄¹ and 1₁¹ coal layer are secondary minable coalbed. 2₁ and 2₀² coal layers are low ash, super-low and low sulfur, low phosphorus, medium fixed carbon, strong cohesiveness, super and high calorific value, better dressing; they belong to 1/3 coking and full coking coal, and can be used as coal blending of coking skeleton and the main coking coal. 1₄², 1₄¹ and 1₁¹ coal are medium ash, medium and high sulfur, super-low and low phosphorus, medium fixed carbon, super-strong cohesiveness, high and super-high calorific value, respectively belong to low dressing 1/3 coking coal, medium dressing fat coal and full coking coal, which can be used as a general power coal as well as in coking blending.
