摘要
矿山隧道周围某一区域的岩溶和断裂构造将对隧道施工造成安全隐患。为了避免施工风险和预防施工过程中可能出现的地质灾害,查明隧道岩溶及断裂等的赋存情况都十分必要。本文介绍了EH4连续电导率成像系统的原理、特点、工作方法和数据处理,然后结合具体矿山隧道工程中的应用实例和效果,结果表明,该方法具有预测溶洞和断裂带的能力。
The karst and fault structure of a certain area around the mine tunnel will pose a safety hazard to the tunnel construction. In order to avoid the risk of construction and the possible geological hazards in the construction process, it is necessary to find out the occurrence of karst and fracture of the tunnel. EH4 continuous conductivity imaging system are introduced the principle, characteristics, working method and data processing, and then combined with the specific application of the mine tunnel engineering and effect, the results show that this method have the ability to predict caves and fault zone.
