巷道围岩多参数监测装置

Multi-parameter Monitoring Device for Roadway Surrounding Rock

摘要: 为预防巷道围岩事故的发生,开发了巷道围岩多参数监测装置,实现了围岩内部应力、离层及巷道表面位移的监测。介绍了巷道围岩多参数监测装置的组成,论述了其测量原理和使用步骤,实验室测量试验结果与实际吻合度较好。监测数据可用于评价围岩的支护、变形、收敛和稳定性,可以大大降低此类围岩事故的发生率。

Abstract: To prevent the occurrence of roadway surrounding rock accidents, a new type of roadway surrounding rock monitoring device was developed, and the internal stress, separation and roadway surface displacement monitoring of surrounding rock were realized. The composition of multi-parameter monitoring device for roadway surrounding rock is introduced in the paper. The measuring principle and application steps are discussed too. The experimental result of laboratory measurements is similar to the actual. The monitoring data can be used to evaluate the surrounding rock support, deformation, convergence and stability, and so that the incidence rate of such surrounding rock accidents will be reduced greatly.
