摘　　要：晋能控股忻州公司泰安煤业11#煤、12#煤平均层间距为3.9 m,在巷道布置和顺槽掘进过程中易受上覆煤层采动和区段煤柱叠加应力影响,巷道变形严重且维护困难。本文通过方案类比分析、理论分析和FLAC^(3D)数值模拟软件研究上覆煤层区段煤柱下底板煤岩层内的应力分布状态及传导规律,确定近距离煤层巷道布置合理方案。The average interval between the 11# coal and 12# coal seams of Jinneng Holdings Xinzhou Company′ s Tai′ an Coal Industry is 3.9 m.During the process of roadway layout and tunnel excavation,it is susceptible to the influence of overlying coal seam mining and the superimposed stress of section coal pillars,resulting in severe deformation and difficult maintenance of the roadway.This paper studies the stress distribution state and conduction law in the bottom coal layer under the coal pillar in the overlying coal seam section through scheme analogy analysis,theoretical analysis,and FLAC~(3D) numerical simulation software,and determines a reasonable plan for the layout of close distance coal seam tunnels.
