矿区大地构造位置处于华北坳陷内黄凸起与东明凹陷的交接部位,属开封成煤小区.含煤岩系为石炭—二叠系,含煤13层,可采煤5层,其中二1煤为主要可采煤层,二02、一42、一41和一11煤为次要可采煤层.二1、二02煤均属低灰、特低硫-低硫、低磷、中等固定碳、特强粘结性、高热值-特高热值、良等可选煤,分别属1/3焦煤和焦煤,可作炼焦骨架配煤和主焦煤;一42、一41、一11煤均属中灰、中高硫、特低磷-低磷、中等固定碳、特强粘结性、高热值-特高热值煤,分别属低等可选的1/3焦煤、中等可选的肥煤和焦煤,可作一般动力用煤,也可作炼焦配煤.

Coal Quality Characteristics in Mazhuangqiao of Puyang City

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.
