摘　　要：针对扎赉诺尔矿务局灵东煤矿特殊的地质条件——厚煤层、煤层上为松软含水层,基于理论分析、数值模拟和物理模拟进行了系统的研究,在此基础上提出了具体解决途径,使用合理的断面设计和锚杆索+网梁带综合支护技术很好地解决了上述切眼的支护问题。该技术的成功运用将获得巨大的安全和经济效益,为扎赉诺尔矿务局今后松软含水层下大断面切眼施工提供了一定的技术借鉴作用。Summed up under the soft aquifer supporting large cross section lane technology, deal with the problems, concrete solutions were put forward approach. The bolt - mesh beam cable ＋ metal stent ＋ jet ＋ reinforced concrete pouring of concrete combined supporting technology were used successfully in Lingdong Mine where had very special geological conditions. The successful application of this technology will have enormous security and economic benefits to Zha Lai Knoll Coal Industry Co. Ltd. , at the same time it provided a favorable technical support for the company＇s future aquifer under the construction of large cross section lane.
