一种互相关让均压技术在复杂地质区域支护中的应用

Roadway support technology of complex geological area based on the theory of coupled let equalizing

针对新安煤矿采区工作台的巷道结构组成,煤层支撑顶板损害严重,存在较大的构造应力,以及支护比较困难的现状,引入了互相关让均压技术并结合当地地质特征,阐述了被支护区域巷道损坏的原因和对巷道支护产生影响的几个方面,阐述了针对软岩巷道深部及破坏层的巷道支护技术路线和相关措施,同时对位移观测点的数据进行了分析,结果表明可以作为相同地质分布的井下巷道顶部以及帮部支护技术,能够满足安全生产的需要。

For formations constructed roadway conditions of Xin An mining area, Seam roof damage, Large tectonic stress, Supporting greater difficulty, Proposed to optimize the coupling allows equalizing support technology combined with local geological conditions, Expounded on the regional roadway damage mechanism and the effect of the roadway influential factor for the proposed research program over the roadway and technical measures and undermine regional fault segment, while the mine pressure observation data were analyzed as similar tunneling technology and mine safety mining of reference.
