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。
玉山煤礦含煤地層為吳傢坪組，可採煤層2層，具有中灰、中等揮髮分、高硫分、低燐分、特低—低氯，低砷、高氟，中高髮熱量的煤質特徵，煤類豐富，呈條帶狀分佈。通過對區內沉積環境和煤的變質作用2箇方麵的分析，闡述瞭形成煤層高硫、中灰特徵的影響因素，解釋瞭煤類分帶現象，併指齣瞭主要煤質指標的變化規律。

Wujiaping formation is the coal-bearing strata in Yushan coal mine.It contains two main minea-ble coal strata.It has the characteristics of medium ash and volatile,high-sulfur,low phosphorus,ex-tremely 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 metamor-phism 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.
