摘要
通过对神东矿区影响煤层煤质地质因素的分析,发现沉积环境是影响煤层煤质的主要地质因素,煤层灰分含量、灰成分以及煤显微组成、显微类型等均受沉积环境的控制,而煤化作用条件则通过后生矿物的形成这一方式在一定程度上影响煤层的煤质特征.
The analysis on geological factors of coal quality variation indicated that sedimentary environmental is the main factor.Ash content and composition,maceral composition were controlled by sedimentary environmental of coal seams.New mineral formation during coalification influenced the coal quality to some extent.
