摘　　要：为研究火成岩岩床侵入对煤层稳定性的影响,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,对比分析了72煤岩浆侵入区和非侵入区的煤层结构、厚度和倾角等特征.结果表明:72煤受火成岩侵蚀后成为煤、火成岩、炭质泥岩、天然焦及大夹焦等不等形式的互层结构,使72煤成复杂结构煤层.火成岩侵蚀区的煤层厚度及其倾角变异系数均大于无火成岩侵蚀区域,煤层的突出危险性增加.In order to learn the influence of igneous rock bed intrusion on coal seam stability,taking the No.72 coal in 81 mining area of Zouzhuang Coal Mine as the research object,and using the method of mathematical statistics and on-site verification,the coal seam structure,thickness and dip angle of the No.72 coal magma intrusion area and non-invasion area are compared and analyzed.Results show that the No.72 coal is eroded by igneous rock to become interlayer structure such as coal,igneous rock,carbonaceous mudstone,natural coke and large coke,which makes the No.72 coal into a complex structure coal seam.The thickness of the coal seam in the igneous rock erosion area and the coefficient of variation of the dip angle are larger than those in the area without igneous rock erosion.
