摘　　要：邻水县小庄子煤矿开采将穿越邻垫高速公路铜锣山隧道,小庄子煤矿开采通过设置运输巷道及保安煤柱确保铜锣山隧道的安全运营,煤矿运输巷道开挖对隧道的影响以及保安煤柱范围的研究成为小庄子煤矿开采的前提。针对以上问题的研究,得出了一套运输巷道开挖对隧道影响的评价体系,确定了保安煤柱的范围。The mining of Xiaozhuangzi Coal Mine will go through Tongluoshan tunnel.To guarantee the safety of Tonglongshan tunnel,Xiaozhuangzi Coal Mine has decided to build special transportation roadway and coal pillars.Thus the research of the mining influence of the transportation roads on the tunnel and the range of coal pillars is the premise of the mining of Xiao Zhuangzi Coal Mine.This paper mainly focuses on the aboving questions.Through careful studying,this paper proposes an evaluation system of the mining influence of the transportation roads on the tunnel.Besides,the range of coal pillars can be determined.

关 键 词：煤矿 运输巷道 开采 既有隧道 稳定性 保安煤柱
