firstly, early preparation: the device is respectively placed in different mine holes, low-boiling-point liquids with different boiling points are respectively filled into the lower half parts of the cylinder bodies (14) in different devices, which are positioned in the limiting blocks (12), volatile solid odorous agents with different volatile and tastes and diameters larger than the air holes I (34) are filled into the volatile box (29), pigment powders with different colors are filled into the dyeing box (30), and the solid odorous agents fall into the box bodies I (35) through the guide pipes I (28);

secondly, detecting that when the temperature of the coal is increased by oxidation air, the first cylinder (14) is made of diamond, heat can be rapidly transferred to the internal low-boiling-point liquid, the low-boiling-point liquid is vaporized and expanded to push the sliding bottom plate (13) to move upwards, the sliding bottom plate (13) moves upwards to drive the T-shaped rod (15) to move upwards, the T-shaped rod (15) moves upwards to ensure that the T-shaped rod (15) does not abut against the baffle (22), the spring (39) releases stored force to push the baffle (22) towards the central direction of the first box body (1), the baffle (22) pushes the first valve column (23) to open the fourth guide tube (24), liquid gas in the second gas cylinder (10) is rapidly vaporized after the fourth guide tube (24) is opened to generate extremely high gas pressure, and the gas is sprayed into the fifth guide tube (18) through the fourth guide tube (24) to push the first lifting column (19) to move upwards along the, the pressure reducing valve (37) can discharge quantitative gas to keep the internal pressure stable when the internal air pressure of the duct five (18) is too high, the chute (20) can prevent the movement stroke of the lifting column one (19) from exceeding the length of the duct five (18), the lifting column one (19) moves upwards to drive the long rod (5) to move upwards, and the long rod (5) moves upwards to drive the lifting column two (6) and the lifting column three (2) to move upwards;

thirdly, alarming: the lifting column III (2) moves upwards to drive the annular ring (26) to move upwards, the annular ring (26) moves upwards to enable the valve column III (25) to move upwards to open the guide pipe III (27), when the guide pipe III (27) is opened, the liquefied gas in the guide pipe III is quickly vaporized and generates great pressure, the gas is flushed into the box body II (31) through the guide pipe III (27), the gas drives the solid odorous agent in the box body I (35) to be volatilized in an accelerated manner after passing through the air hole I (34), when the gas passes through the lower part of the guide pipe II (33), the check valve II (40) is opened according to the principle that the gas flow rate is large and the pressure is small, the pigment powder in the dyeing box (30) is mixed into the gas through the guide pipe II (33) to dye the gas, at the moment, the gas has the same color and odor, the gas is blown to the outside through the filter screen (32), and reaches the outside gas under the, the gas is diffused to the upper corner, so that people on the working face can indirectly know the position of the coal mine about to self-ignite and the existing temperature of the coal mine according to the smell and the color of the gas;

fourthly, cooling: the second lifting column (6) moves upwards to drive the second valve column (16) to move upwards, the second valve column (16) moves upwards to open the sixth guide pipe (17), water in the spraying tank (7) passes through the sixth guide pipe (17) after the sixth guide pipe (17) is opened and then is converted into water mist through the spraying head (36) to cool the interior of the mine hole, and the coal mine is placed to the maximum extent before a worker arrives to generate spontaneous combustion;

fifthly, returning: when the temperature in the mine hole is normal, the low-boiling-point liquid in the first cylinder body (14) stops boiling, the gas in the first cylinder body (14) below the sliding bottom plate (13) contracts when encountering cold to drive the sliding bottom plate (13) to descend to the top of the limiting block (12), the sliding bottom plate (13) descends to drive the T-shaped rod (15) to descend, the T-shaped rod (15) descends to the original position to abut against the baffle (22), the spring (39) is in a force accumulation state after the baffle (22) is abutted against, the valve column I (23) closes the guide pipe IV (24) to enable the gas cylinder II (10) to stop gas injection, the long rod (5) descends by virtue of the self gravity, the long rod (5) drives the lifting column I (19), the lifting column II (6) and the lifting column III (2) to descend, the lifting column I (19) descends to discharge redundant air through the check valve I (38) and slide to the bottommost of the stroke of the sliding chute (20), the lifting column II (6), the annular ring (26) descends to drive the third valve column (25) to descend, the third valve column (25) descends to close the third guide pipe (27), the third guide pipe (27) is closed to stop air injection of the first air bottle (3), the third lifting column (2) descends to drive the second valve column (16) to descend, the second valve column (16) descends to close the sixth guide pipe (17), and the sixth guide pipe (17) is closed to stop the spraying of water mist from the spraying tank (7), so that the spraying tank is switched back to the original position;

sixthly, regular maintenance: the exhausted gas cylinder I (3), the gas cylinder II (10) and the spraying tank (7) need to be replaced regularly.
