| description | 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 |
