Described monitor is KBU101-200.
Described pressure sensor is the pressure sensor of built-in transmitter.
The method of work of above-mentioned gob side entry retaining roadside packing body and back dynamic monitor is as follows:
1) each monitor and pressure sensor are all set unique geocoding, and the monitor signal on each section monitoring point is transferred to 485 buses by the section junction box, and all section junction boxes are transferred to KJF70 communication substation respectively by the RS485 bus;
2) KJF70 communication branch stands in KJ216 communication main website control down, patrols by the RS485 bus timing and surveys each monitoring point, the monitored data circulation of each monitoring point is presented on the screen of KJ216 communication main website, and monitored data is carried out real-time storage and analysis.
The present invention is applicable to the dynamic monitoring of the gob side entry retaining roadway surrounding rock characteristics of motion.
Good effect of the present invention is:
According to country rock and supporting principle of combined action, can only resist pressure, release pressure by supporting, the compressive strain that allows by the roadside packing material slows down the pressure at other positions, tunnel, and control tunnel bulk deformation satisfies it and produces needs.So, research has a kind of roadside support body that certain supporting resistance is arranged and allow to allow compressive strain, extremely urgent, just need monitor the gob side entry country rock characteristics of motion for this reason, draw its characteristics of motion parameter, press parameter and rational roadway support parameter that foundation is provided for the intensity of roadside packing body, distortion rationally allow.
