摘要：煤矿开采中一次采全高沿空留巷技术较为成熟，但特厚煤层分层开采金属网假顶下沿空留巷技术尚不多见，因待浇筑空间的支护问题是制约沿空留巷的主要难题，没有可以借鉴的理论成果和实践经验。白芨沟煤矿分层开采金属网假顶下架棚金属支架巷道沿空留巷的实施，不仅可以效解决白芨沟煤矿掘进巷道接续紧张的问题，而且可以为分层开采金属网假顶下架棚金属支架巷道沿空留巷提供理论依据和实践经验。

Abstract: in coal mining, the technology of Retaining Roadway along goaf with full height at one time is relatively mature, but the technology of Retaining Roadway along goaf under metal mesh false roof in layered mining of extra thick coal seam is rare. Because the support of the space to be poured is the main problem restricting retaining roadway along goaf, there is no theoretical achievement and practical experience that can be used for reference. The implementation of Retaining Roadway along goaf in layered mining of metal mesh false roof under shed metal support roadway in Baijigou coal mine can not only effectively solve the problem of tight connection of driving roadway in Baijigou coal mine, but also provide theoretical basis and practical experience for retaining roadway along goaf in layered mining of metal mesh false roof under shed metal support roadway.<br>

In coal mining, the technology of retaining gob-side entry with full height at one time is relatively mature, but the technology of retaining gob-side entry under false roof in extra-thick coal seam is still rare, because the support of the space to be poured is the main problem that restricts retaining gob-side entry, so there is no theoretical achievement and practical experience for reference. The implementation of gob-side entry retaining in metal frame roadway under false roof in layered mining in Baijigou Coal Mine can not only effectively solve the problem of tight connection in driving roadway in Baijigou Coal Mine, but also provide theoretical basis and practical experience for gob-side entry retaining in metal frame roadway under false roof in layered mining.
