摘　　要：煤矿巷道安全畅通对于煤炭资源的安全开采及矿井高产高效生产具有重要意义。本文针对山东能源临矿集团新驿煤矿窄煤柱沿空巷道围岩控制中存在的两帮弱结构、顶板淋涌水突出、采动影响剧烈的问题,提出顶板高强锚杆索非对称支护、两帮高强锚杆加固与顶板有效防水的综合控制对策。工程实践表明,采用该支护方案后53d左右,沿空巷道变形趋于平稳,为类似巷道围岩控制提供了借鉴。The safe and smooth flow of coal mine roadway is of great significance for the safe mining of coal resources and the high production and high efficiency production of mines.In view of the problems of two weak structures,prominent roof water surge and severe mining impact in the surrounding rock control of the narrow coal pillars along the narrow coal pillar of Xinyi Mine of Shandong Energy Mining Group,the asymmetric support of the roof high-strength anchor cable was proposed.Comprehensive control measures for the reinforcement of two sets of high-strength anchors and effective waterproofing of the roof were given.The engineering practice showed that the deformation of the roadway along the roadway tended to be stable after about 53 days of the support scheme,which provided a reference for the surrounding rock control of similar roadway.
