丰予井田煤系地层沉积环境及4号煤层的赋存变化规律

Depositional Environment of Coal-measure Strata of Fengyu Coal Field and Variation Law of No.4 Coalseam Occurrence

通过分析本井田含煤岩系地层沉积环境,可以得出本井田的聚煤规律。4号煤层属于丰予井田可采的稳定煤层之一,煤厚总体呈西北厚,东南薄的变化趋势,分析4号煤层的赋存状态及变化规律,对该煤层的勘探开采具有实际意义。

Through the analysis of the depositional environment of the coal measure strata, the coal accumulating law of this coal field can be drawn. No. 4 coalseam is one of the stable minable coalseams in Fengyu field, which is generally thicker in northwest and thinner in southeast. Analysis of the conditions of No. 4 coalseam occurrence and the law of variation has a practical significance to its exploration and mining.
