基于巷道破坏机理分析的锚索箱梁支护技术

Support technology of Cable Box Girder Based on Analysis of Tunnel Failure Mechanism

现如今,深部软岩支护是目前学术研究及煤炭井巷工程的设计与施工都特别关心的核心问题之一。为了摸清深部井巷工程的变形破坏特征及井巷围岩的合理支护方法,本文主要针对麻将梁矿,采用施工现场测量数据为基础,辅以室内试验研究,最后建立相应的力学模型,深入分析传统的单一式支护在深部巷道中所面临的支护结构受力状态不合理、力的传递不科学等问题,最终设计出了一种新型的让压型—锚索箱梁支护方案。

Nowadays, the deep soft rock support is one of the key problems of special concern in design and construction of academic research and coal roadway engineering. In order to find out the characteristics of surrounding rock deformation and failure of the roadway and the reasonable support engineering protection method, this article mainly aims at the majialiang coal mine, using the measurement data of the construction site and based on laboratory experiments, then establishes the corresponding mechanics model, in-depth analysis of a single type of traditional supporting face in deep roadway in support structure unreasonable and the unscientific transfer force, finally design a new type of pressure-anchor box girder supporting scheme.
