The monitoring method comprises: collecting microseismic signals generated by rock mass fracture, and using a short-term average/long-term average method to pick up effective microseismic waveform data (101); extracting microseismic feature vectors from the effective microseismic waveform data, and executing different compression strategies according to the microseismic feature vectors to obtain a compressed data packet (102); scheduling an NB-IOT module by using a sleep-wake algorithm, waking up the NB-IOT module when data needs to be sent, and putting the NB-IOT module into a sleep state when data does not need to be sent (103); when the NB-IOT module is in a wake state, sending the data packet to a cloud platform (104); and the cloud platform analyzing the received data packet, and if an early warning condition is met, sending early warning information (105). The NB-IOT technology is combined to solve the long-distance transmission problem of wirelessly monitored data of rock mass fracture instability microseismic signals, while the working time of the NB-IOT module is prolonged, thereby providing important practical value for geological hazard prevention and reduction.
