PROBLEM TO BE SOLVED: To provide a method and device for prevention of spontaneous ignition of a stored coal capable of detecting the temperature change of the coal stored in a coal storage tank without using a wire rope to prevent the spontaneous ignition of the coal from occurring.SOLUTION: A method for prevention of spontaneous ignition of a stored coal includes: charging and embedding plural capsules 3 in which a temperature sensor 3a and radio module 3b are built in from a charge port 1a of a coal storage tank 1 together with the coal; determining the positions of plural embedded capsules 3 in the coal storage tank 1 by a data-processing terminal 4; preparing a coal temperature distribution inside the coal storage tank 1 in the data-processing terminal 4; and outputting an operation signal 4a to a discharge machine 2 corresponding to the embedded place of the capsule 3 detecting that the temperature of the coal exceeds an allowance based on the temperature distribution to discharge the capsule 3 together with the coal. The capsule 3 discharged with the coal is recovered by a recovery vessel 5.SELECTED DRAWING: Figure 1
