Monitoring method for remotely measuring and controlling damage depths of floor strata

The invention relates to a monitoring method for remotely measuring and controlling damage depths of floor strata. The monitoring method is characterized in that vibrating wire type rock fracture meters and temperature sensors are arranged in drilled holes of a seam floor stratum, and a monitoring system comprises a signal acquisition unit, signal transmission cables and a reading device; and the signal acquisition unit acquires displacement and temperature data of fractures at measuring points of the floor stratum, the displacement and temperature data are transmitted to the reading device via the signal transmission cables, analog quantities are converted into digital quantities on the reading device, and the digital quantities are recorded and displayed. The monitoring method has the advantages that damage conditions of the measuring points of the floor stratum of a stope can be monitored before a roof propelled along with a working face in a mining procedure falls, damage conditions of the measuring points of the floor stratum can also be monitored after the working face is pushed across a monitoring point and the roof falls, and accordingly the integral mining procedure is continuously monitored; and the maximum damage depth and an activity low of the floor stratum of the working face can be obtained by analyzing the monitoring data, and a foundation is laid for predicting water inrush of a seam floor.
