The present disclosure provides a device and a method for real-time monitoring the movement trajectory of mine roof strata, which relates to the technical field of the movement monitoring of mine roof strata. The device described in the present disclosure has fewer components, and the assembly process is simple and fast during use. It can be assembled and used according to the actual length of the monitoring borehole; the structure of the device is relatively simple, easy to manufacture, uses fewer precision instruments, and has a lower cost; by using the device of the present disclosure for real-time monitoring of mine roof strata, the movement trajectory of mine roof strata can be monitored in real-time, accurately, and continuously, providing more detailed strata information for disaster prevention and control such as mine pressure, strata control, and rock burst.

Device for real-time monitoring movement trajectory of mine roof strata and method thereof

A system and a method for monitoring overlying roof rock and coal pillar in gob-side entry are provided. The system includes top monitoring stations, coal pillar comprehensive monitoring stations, roof stress monitoring stations, and a master computer. Top monitoring stations are arranged in the crossheading to monitor the working face, coal pillar comprehensive monitoring stations are arranged in the upper roadway of the lower coal seam working face to monitor the coal pillars, and roof stress monitoring stations are arranged in the mining area main roadway to monitor the coal pillars. Monitoring the stress and deformation distribution of coal pillars in the goaf and the movement and failure process of overburden strata structure through the master computer control each monitoring station. The monitoring stations ensure that the overburden strata movement monitoring stations are still in working condition after the goaf is formed by mining in the working face.
