The spontaneous combustion of the coal pile is caused by the internal temperature of the coal pile gradually increasing due to the oxidation phenomenon and heat storage phenomenon of the coal itself. Therefore, even if water is sprinkled from the outer surface of the coal pile for cooling, it is not effective for lowering the internal temperature and a large amount of water is required. Therefore, the temperature inside the coal pile can be accurately and regularly grasped by the temperature measurement robot as described above to identify a point close to the spontaneous combustion, and the water injection nozzle provided in advance at that point can be used for the inside of the coal pile. By directly pouring water, the temperature in the vicinity can be lowered by pouring a proper amount of water in a short time, and spontaneous ignition can be prevented.

First, the internal temperature of the coal pile is sequentially measured at regular intervals by the temperature measuring robot 1 arranged at regular positions, and the data processing device 3 determines whether or not it is a dangerous temperature. . If the temperature at each measurement point is below the critical temperature, the cycle measurement mode
The measurement points are sequentially measured as 11t, 12t, ... And one cycle of measurement is completed at nn-1t, nnt. The measured temperature of each point is stored in a floppy disk or the like together with date and time, weather conditions, coal type, and the like. Then, after a certain period of time has elapsed, the cycle measurement is repeated again.

However, when a point above the dangerous temperature appears during the cycle measurement, it is judged that the point is that the temperature of the coal itself rises due to oxidation or heat storage.
At that point, continuous measurement is performed by switching to the continuous measurement mode. However, for other measurement points, the cycle measurement continues. Then, when the internal temperature at the point at which the dangerous temperature is reached rises to the spontaneous ignition temperature with the passage of time, the mode is switched to the water injection cooling mode and the water injection drive device 4 is operated to inject water for a certain time. Then, when the temperature at that point falls below the dangerous temperature due to the water injection, the mode is switched to the cycle measurement mode and the cycle measurement is performed. However, if the temperature at that point does not fall below the critical temperature even after pouring water, continuous measurement is continued in the continuous measurement mode.

Next, FIG. 3 shows the temperature characteristics inside the coal pile. First, as shown in FIG. 3 (a), the internal temperature of the coal pile is almost stable because the surface of the coal pile is gradually dried by the atmospheric heat and the internal heat after the coal is stored in the coal stock yard. The temperature rises. This is the stable rising period. And
When the internal temperature becomes equal to or higher than the dangerous temperature T 1 , the water accumulated inside the coal pile diffuses and evaporates at once, so that the internal temperature rapidly rises (a steep rise period). Eventually, the temperature becomes higher than the spontaneous ignition temperature T 3 and spontaneous ignition occurs.

On the other hand, FIG. 3B shows the temperature characteristic when this system is used. When the internal temperature is T 1 or less, the cycle measurement is performed and the temperature is T
When it enters the range of 1 to T 3 , continuous measurement is performed at that point. Then, when T 3 is exceeded, water is injected by the water injection nozzle for a certain period of time, and the temperature at that point is lowered by the cooling effect.

FIG. 4 shows the temperature distribution inside the coal pile. Generally, as shown in the figure, the temperature of the middle part between the surface and the bottom of the coal pile is the highest. Therefore, the temperature Tm at the height of the maximum temperature is measured, and when the temperature Tm exceeds the spontaneous ignition temperature T 3 , water is immediately poured directly to the point of the height to cool the portion. In this way, it is possible to prevent spontaneous ignition of the coal pile with an appropriate amount of cooling water.

On the other hand, since the water injection nozzle 12 needs to inject water into the entire circumference of the robot, a plurality of water injection spray holes are arranged in the entire circumference of the robot here.
