Microbial dust suppressant with thermal stability for mine and use method of microbial dust suppressant

The invention belongs to the technical field of dust treatment of well mining and strip mines, and particularly relates to a mining microbial dust suppressant with thermal stability and a use method thereof, and the mining microbial dust suppressant is prepared by compounding crude glycerin, a precipitation ionic liquid and a BM strain mixed solution according to a volume ratio of (0.8-1.2): (1.8-2.2): (1.8-2.2). The BM mixed solution is a mixed solution of an industrial strain and a coal sample extraction strain, and the BM mixed solution is cultured for 24-48 h according to the optimal mildew production condition and then is mixed with the crude glycerin and the precipitated ionic liquid in proportion to obtain the thermal-stability microbial dust suppressant. The heat-stable microbial dust suppressant is uniformly sprayed to the dust on the open slope, the spraying amount each time is 6-10 L/m < 3 >, and spraying is performed for 3-6 times. The result shows that the crude glycerol extracted from the waste
