大断面巷道合理支护参数的选取研究

Study on the Selection of Reasonable Support Parameters for Large Section Roadway

在大断面巷道掘进过程中,支护工艺技术是一项最为重要的技术。探讨大断面巷道掘进支护工艺技术具有重要的应用意义。本文首先对霍宝干河煤矿+80水平西翼轨道巷、变电所的支护进行了详细计算,提出了具体的施工标准要求。实践证明,支护完全满足后期的安全生产需求。

Supporting technology is the most important technology in the process of large section roadway driving. It is of great significance to explore the supporting technology of large section roadway driving. In this paper, the support of the West Wing track and substation in the ＋80 level of Huobaoganhe Coal Mine is calculated in detail, and the specific construction standard requirements are put forward. Practice has proved that the support fully meets the later safety production needs.
