Method for exploring and monitoring temperature of mine goaf based on magnetic method

The invention discloses a method for exploring and monitoring the temperature of a mine goaf based on a magnetic method. The method comprises the steps of 1, fixed-point pre-burying of a coal seam goaf magnetic target; 2, establishment of a magnetic target distribution model; the method comprises the following steps of 1, arranging a monitoring network on the ground, and monitoring magnetic parameters through magnetic detection equipment, 4, converting the magnetic parameters into temperature data and judging whether a fire disaster occurs or not, and 5, taking measures according to the judgment result of the step 4. The characteristic that the magnetic susceptibility of the magnet and the temperature are in a linear relation is utilized, the magnetic susceptibility of the arranged magnetic target is monitored in real time to obtain the temperature change of the position of the magnetic target, precautionary measures are taken in time, meanwhile, when a fire occurs, the position of a fire source can be detect
