补作井田可采煤层灰、硫特征及聚煤环境分析

Analysis on Characteristics of the Ash Yield and Sulfur Content and Coal Accumulating Environment in Coal Seams of Buzuo Mine

摘要: 依据补作井田大量的煤田地质勘探资料及煤储层灰分和硫分数据，对主要可采煤层灰分产率、硫分含量的分布特点进行分析，并通过原煤灰分产率、硫分含量特征对研究区聚煤环境进行了划分。研究结果表明：垂向上，随着可采煤层埋深的增加，灰分产率和硫分含量呈降低趋势，但平面上灰分产率和硫分含量的变化较大。总体上，可采煤层灰分产率与硫分含量呈正相关关系，灰分产率、硫分变化与海侵影响下的泥炭沼泽聚煤环境有显著的关系。

Abstract: Based on a large number of coal field geological exploration data and ash and sulfur data, the characters of the changes and distribution of the ash yield and sulfur content were emphatically analyzed, and through the characters of the ash yield and sulfur content, the coal environment of study area is measured. The results showed: In vertical as the depth of coal seam increased, ash and sulfur content was generally decreased, however, there was a large change in the plane. In general, ash and sulfur of coal showed a positive correlation, the change of ash and sulfur was obviously related with the depositional environment of peat swamp under the extraordinary influence of transgression of the sea.
