Visualization device and monitoring method for roadway surrounding rock plasticity destruction process

The invention discloses a monitoring visualization device for the roadway surrounding rock plasticity destruction process and further discloses a monitoring visualization method for the roadway surrounding rock plasticity destruction process. The monitoring visualization device comprises three parts of a ground data processing and control subsystem, a downhole data transmitting communication subsystem and a downhole sensing data collecting subsystem. The ground data processing and control subsystem comprises a main monitoring computer; the downhole data transmitting communication subsystem comprises a data communication interface; the downhole sensing data collecting subsystem comprises one or more displacement sensors including one or more of the multi-point displacement meter sensor, theoptical grating sensor, the capacitance grating sensor, the magnetic grating sensor and the heat conductivity sensor; and data collected by the displacement sensors are transmitted to the main monitoring computer through the
