摘　　要：为研究火成岩侵蚀对煤质的影响,以邹庄煤矿81采区72煤为研究对象,采用数理统计和现场验证的方法,对81采区火成岩的侵入方式以及72煤层的侵蚀区与非侵蚀区的工业性指标、煤发热量、煤全硫含量、煤黏结指数的变化情况进行对比分析.结果表明:火成岩侵入煤层的方式大致分为3个方向;火成岩侵蚀区72煤的煤层结构变复杂,稳定性降低,危险性增加,导致其工业价值降低.In order to study the influence of igneous rock erosion on coal quality,the 72 coal in the 81 mining area of Zouzhuang Coal Mine is used as the research object,and the exploration original data analysis method is used to analyze the igneous rock intrusion method and make a comparative analysis of changes in the 72 coal industrial indicators,coal calorific value,coal total sulfur content,and coal caking index in the erosion and non-erosion areas.Results show that the way of igneous intrusion into coal seam is divided into three directions,and the coal seam structure of 72 coal in igneous erosion area becomes complex,the stability decreases and the risk increases,which leads to the decrease of its industrial value.
