通柘煤田_(—1)^(—2)煤层的煤质变化规律

Coal Nature Variation of Coal Seam Ⅱ_1~2 in Tongzhe Coalfield

河南省通柘煤田煤炭资源丰富,主要可采煤层为山西组二_1~2煤,煤层结构简单,煤厚稳定,煤类以无烟煤和贫煤为主,有少量的瘦煤、焦煤和天然焦,煤化程度从东向西逐渐升高,低灰、低~特低硫、特低~低磷、特低氯、高~特高热值。

Coal resources are abundant at Tongzhe coalfield in Henan Province. coal seamⅡ1^2 of Shanxi Formation is the main minable seam. The structure of coal seam is simple and the coal thickness is sta ble. The major coal types are anthracite coal and lean coal, and there is a small amount of lean coal, coking coal and natural coke. The degree of coalification increases gradually from east to west, which in- cludes those low in ash, low to super lower in sulfur, low in phosphorus, especially low in chlorine and high to Super higher in calorific value. The coal in this area can be use as power coal and civil fuel.
