Study On The Monitoring Technology Of Bolt Timber In The Stopping Excavation

The quality monitoring of bolt is the important work which guarantees the bolt quality and safety production. In this paper,by the monitoring of rock stress behavior around mine opening and the monitory of anchoring force,the monitoring of the bolt is realized. Through the work of this paper,the deep multi-point deformeter is developed,which has many excellencies. Such as apt process,handy installing,low cost,exact reading. This deformeter is used to monitor not only the laneway roof displacement but also the roof joint. The software of bolt monitor is workouted.At last,it is applied in Western No.3 405 laneway of Xiao-nan mine. It plays an important role for guaranteeing the safety production and improving the work efficiency.
