我矿在二期工程施工初期,部分在软岩中掘进但采用常规支护形式的巷道,顶板出现较大变形,底板产生底鼓,巷道埋深大且有地质构造影响造成的高地压现象已开始初步显现,并有进一步发展的趋势.考虑到井底车场巷道及周围硐室服务年限长,为了确保安全和工程质量,减少后期巷道维修工程量,决定开展千米埋深高地应力条件下巷道支护技术研究与应用,并取得了良好效果.

Due to the the application of traditional supporting form to partial roadway during the drive, the roof was out of shape and floor was heaved. In addition, the largely burried- deep roadway as well as the influence of geological structures results in converse "High-pressure phenomenon". This study made an in-deep analysis and application of roadway supporting technology under high geostress and km buried-depth with reference to the limation of shaft station roadway and cavern service based on the construction practice in the beginning of the second phrase. We expect that this study will be beneficial to the guarantee of engineering safety , the improvement of engineering quality and reducing the burden of engineering quantity at the end phrase. To sum up, the experimental results demonstrated that the analysis and ap-plication of roadway supporting technology made satisfactory effects. Technically and practically, this study was of much value.
