底角锚杆作用效果的现场试验研究

Field tests study on bottom corner anchor acting effect

本文目的在于揭示底角锚杆在煤矿岩石巷道稳定性方面的作用,并论证关键控制点的加固对于巷道整体稳定性控制的重要意义。本文以现代力学为基本理论依据,以淮北矿业股份有限责任公司杨庄煤矿IV53采区轨道下山为研究对象,以现场实测数据为研究论据,不仅论证了底角锚杆在控制巷道底臌方面的巨大作用,同时也论证了底角锚杆在控制巷道整体稳定性方面的显著效果。文章不仅给出了大量的现场实测数据,同时也较为详尽地介绍了底角锚杆特殊的施工方法以及特殊的工程地质条件,研究结果对于我国煤矿软岩巷道底臌治理及巷道整体稳定性控制机理与方法的研究具有较为重要的指导与参考价值。

The article aims to reveal the function of bottom corner anchor in stabilizing coal mine rock roadway,and argues for the importance of strengthening essential control point to control the whole stability of the roadway.Based on modern mechanics as the basic theory,based on the track down the mountain in IV53 panel in huaibei mining shares limited liability company Yang Zhuang coal mine as the research object,and the field measured data was regarded as the argument.not only the huge role of bottom corner anchor which was used to control floor heave is proved,but also the significant effect of bottom corner anchor which was used to control the roadway overall stability.In present article,not only a lot of the field measured data was given,but also the special construction methods and special engineering geology condition were more detailed introduced.Research results have an important guidance and reference value to the control mechanism study of overall stability of coal mine soft rock tunnel and floor heave.
