摘要
本文从巷道围岩的工程地质特性出发,总结并研究了广西那龙二号井软岩巷道的变形力学机制及支护特征,运用预留刚柔层技术来解决蒙脱石型软岩巷道支护难题并获得成功。
Based on the geotechnical characteristics of the rock surrounding roadways, the papersummarizes and analyses the mechanism of de-formation of the roadway driven in soft rock atshaft No. 2 of Nalong,Guangxi province. anddiscusses the key techniques in successfully supporting them. That is, the supporting problemthere was solved by leaving a rigid-flexiblelayer in advance. And the success demonstratesthe effect of the theory in practical applicationand forecasts the prospects of its spread.
