Monitoring and early warning method for abnormal temperature area of coal pile

The invention provides a coal pile temperature anomaly area monitoring and early warning method, which comprises the following steps: S1, drilling a hole in the ground for stacking a coal pile, and arranging a vibration wave receiving sensor in the drilled hole; then drilling ground grooves according to the column number of the drill holes, drilling mu + 1 ground grooves if mu columns of drill holes exist, and enabling any column of drill holes and any row of drill holes to be connected through the ground grooves; s2, arranging a vibration wave source on the outer surface of the coal pile; S3, collecting vibration wave signal data; s4, after collecting the signal data of the vibration waves emitted by the m vibration sources received by the n vibration wave receiving sensors in one period, transmitting the vibration wave signal data to a vibration wave data analysis processing host; the data analyzing and processing host analyzes and processes the monitoring data in real time and converts the vibration wave s
