摘　　要：针对云南老厂矿区四堪区主要可采煤层灰分、硫分的分布特点和变化原因进行分析，并利用灰成分对研究区聚煤环境进行了划分。研究结果表明，主采煤层垂向上灰分变化较小，平面上变化较大，而硫分含量则随深度增加逐渐升高。煤层灰分与硫分存正相关关系，灰分和硫分的变化与海侵影响下的泥炭沼泽聚煤环境有显著的关系。The ash and sulfur distribution characteristics and change of main coal seams in the fourth exploration area of Laochang coalmine are analyzed, coal forming environment are differentiated according to the composition of coal ash. The result shows： the ash yield of main coal seams changes a little at vertical direction while changes a lot at horizontal direction; the sulfur content rise with depth increasing; ash yield and sulfur content have positive correlationship; moreover, the variation of ash and sulfur have prominent relationship with peat and swamp forming environment under the influence of ingression.
