平山湖勘查区主采煤层煤质特征及其变化规律研究

摘要

According to hirayama lake exploration area minable seam coal sample of coal and rock , industrial analysis , total sulfur con-tent and calorific value analysis data , evaluated the hirayama lake exploration area main working bed coal , poroperm characteristics , based on this research is mainly focused on the ash content , sulfur content and volatile matter in coal .Studies have shown that hiraya-ma lake exploration area of coal in ash , low sulfur content , high volatile matter , calorific value of characteristics .Raw coal ash content increased gradually from bottom to up , total sulfur content change is not obvious , volatile increase gradually;Plane ash has a "high, middle low"around the distribution characteristics of sulfur content distribution is just the opposite .%根据平山湖勘查区可采煤层煤样的煤岩、工业分析、全硫分及发热量分析数据，评价了平山湖勘查区主采煤层的煤岩煤质特征，在此基础上重点研究了煤中灰分、硫分及挥发分变化规律。研究表明，平山湖勘查区煤具有中灰分、低硫分、高挥发分、中发热量等特征。纵向上原煤灰分自下而上逐渐增大，全硫分变化不明显，挥发分逐渐增大；平面上灰分具有呈“中间高，四周低”的分布特点，硫分分布则正好相反。
