巷道围岩多参数监测装置
Multi-parameter Monitoring Device for Roadway Surrounding Rock
摘要
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.关键词
