| 摘 要： | 控制地下工程软弱岩体特征的一个重要前提是围岩工程地质条件评价以及围岩的地质结构的定量认识,而目前软岩巷道支护难的主要原因是对巷道工程地质条件和围岩结构认识不清、支护对象不明确。基于以上分析,本文以显德汪矿主运输巷道为试验研究对象,采用地震技术对软弱岩体围岩结构进行了全断面探测,实现了岩体结构的空间定位和精确探测,进而为支护形式和支护参数的选择提供了直观可靠的工程地质依据。

| Abstract: | One of important components for a successful control and support of weak rockmasses is to have advance knowledge of engineering geological conditions and structure of surrounding rock. Therefore, lack of knowledge of engineering geological conditions and structure of surrounding rock, which leads no supported objects well defined, eventually resuhs in failures in support of weak rockmasses. In this paper, the authors use seismic exploration technology to fully detect structures of surrounding rock in the main shaft of Xiandewang coal mine, which provides information and parameters needed for design of tunnel support. |
