摘要 太平煤矿南三运输大巷处于地质构造破碎带,通过实测分析,将巷道破坏划分为斜冒型、顶冒型、垮帮型、帮顶冒落型和高冒型五种类型。基于巷道破坏的机理分析,将两帮和顶板作为统一体,建立了自稳隐形拱理论,提出了复修支护的机理和原则,给出了确定支护参数和工艺的方法,通过实践证实是成功的。 The south No.3 transportation roadway in Taiping Mine was in the tectonic broken zone.With the site measurement and analysis,the failures of the mine roadway could be classified into 5 kinds of failures,such as the inclined failing,roof failing,side wall failing,side wall and roof failing and high roof failing.Base on the analysis on the failure mechanism of the mine roadway,taking the two side walls and the roof of the roadway as a completed unity,a self stable hidden arch theory was established.The paper ...
