step three: the flue gas gasification equipment 53 is used for gasifying flue gas liquid, and the gasified flue gas is decompressed to a set pressure through a flue gas pipeline 91 and is output;

step four: setting the temperature of the circulating water bath 15, and preheating the novel foaming device 20 and the coil pipe 16;

fully and uniformly mixing a foaming agent and the treated high-salt mine water in a foaming agent mixed solution storage barrel 10 to form a foaming agent mixed solution, and conveying the foaming agent mixed solution to a liquid path channel 23 of a novel foaming device 20 through a coil pipe 16 by a constant flow of a water-liquid mutual driving unit, and simultaneously supplying parts of flue gas output by a flue gas path pipeline 91 to a gas path channel 24 of the novel foaming device 20 through a gas transmission branch C93 by using a gas transmission branch A76 to prepare foam;

step five: the foam material output from the ejection hole 42 of the novel foamer 20 is conveyed to a three-waste-based foam material mixer 61 in a three-waste-machine foam material preparation chamber 80 through a heat insulation pipeline 52;

inputting the mixed slurry in the slurry storage tank 83 into the screw pump 70 by using the slurry pump 82, and conveying the mixed slurry into the three waste base foaming material mixer 61 by using the screw pump 70;

fully and uniformly mixing the foam material and the mixed slurry through a three-waste-based foam material mixer 61 to prepare a three-waste-based foam material;

step six: pre-treating the self-abutting top region 98 in the gob 94 to make the surface thereof in a flat state; according to the height distance between the top plate crushed rock mass and the bottom plate of the top abutting area 98, the distance between two lane sides, the length distance needing to be filled along the advancing direction and the profile state of the lane section, sewing a goaf leaking stoppage filling bag 97 with a proper size; injecting a three-waste-based foaming material into the lower space of the goaf plugging air filling bag 97 through a three-waste-based foaming material conveying pipeline 95, then building a bracket for supporting the goaf plugging air filling bag 97 in the self-roof-contacted area 98, then injecting the three-waste-based foaming material into the upper space of the goaf plugging air filling bag 97 through the three-waste-based foaming material conveying pipeline 95, and then completely closing the goaf plugging air filling bag 97 to enable the foaming material to self-foam and expand and to be in contact with the roof of the self-roof-contacted area 98; completing the plugging between two lane sides of the gob 94 after the gob plugging air filling bag 97 is fully foamed, and removing the support after the three-waste-based foaming material is completely solidified;
