贵州瓮安玉山煤矿煤质特征及其影响因素

Coal Quality Characteristics and Its Influencing Factors in YuShan Coal Mine

摘要:

玉山煤矿含煤地层为吴家坪组，可采煤层2层，具有中灰、中等挥发分、高硫分、低磷分、特低—低氯，低砷、高氟，中高发热量的煤质特征，煤类丰富，呈条带状分布。通过对区内沉积环境和煤的变质作用2个方面的分析，阐述了形成煤层高硫、中灰特征的影响因素，解释了煤类分带现象，并指出了主要煤质指标的变化规律。

Abstract:

Wujiaping formation is the coal-bearing strata in Yushan coal mine. It contains two main mineable coal strata. It has the characteristics of medium ash and volatile, high-sulfur, low phosphorus, extremely low or low chloride, low arsenic, high fluorine, medium and high calorific value. There are rich coal resource and occurred as banding type. Through analysis on sedimentary environment and metamorphism in this area, influence factors for forming the characteristics of medium ash and high-sulfur have been introduced, and the zoning of coal has been explained. The change law of the main coal quality index has been pointed out.
