Surrounding rock deformation monitoring system for underground roadway of coal mine

The invention provides a coal mine underground roadway surrounding rock deformation monitoring system, which comprises a control module, the control module is electrically connected with a processing module, and the processing module is electrically connected with an optical fiber displacement sensor; the device further comprises a fixing assembly, a measuring assembly and a main board assembly. The control module monitors the deformation distance of the surrounding rock of the roadway through a distributed optical fiber strain monitoring technology; deformation of the surrounding rock of the roadway is monitored through the optical fiber displacement sensor, displacement can be generated in real time when the surrounding rock of the underground roadway deforms, the system can achieve early warning on the disaster of the surrounding rock of the underground roadway, record state signals in real time and draw a curve, and data support is provided for prejudgment and forecast of the disaster of the surrounding r
