Mine aerosol inhibitor spraying method

Abstract

The invention relates to a mine aerosol inhibitor spraying method, which comprises the following concrete steps of 1, pipe laying; 2, external configuration; 3, atomization system assembly; 4, atomizer installation; 5, spraying operation; 6, spraying operation finishing. The method has the advantages that two kinds of goaf fire preventing and extinguishing technologies are combined; under the existing work conditions, the optimized improvement is performed; the implementation is convenient; the effect is obvious; the safe operation environment of the work region is ensured; meanwhile, the injection into a goaf is simultaneously performed at two points; by a mixed aerosol inhibitor solution, the ignition activation energy of the coal can be improved; the coal body can be better adhered; high diffusivity is realized; the inhibition effect is improved; a nitrogen injection and aerosol inhibitor injection integrated inhibitor spraying process is used; the N2 and inhibitor fire prevention double insurance can be realized.

Description

Technical field: [0001] The invention relates to the technical field of mine mining, in particular to a method for spraying a mine gas mist inhibitor. Background technique: [0002] Coal spontaneous combustion fire is the main disaster that threatens the safe production of coal mines, and it has always been the key point of mine fire prevention and extinguishing. Spraying and pouring inhibitors is one of the fire prevention measures taken against coal spontaneous combustion. In the prior art, the use of inhibitors to prevent and extinguish fires usually uses a relatively simple spraying method, which sometimes leads to problems such as insufficient spraying radiation range of inhibitors and inability to penetrate deeply. [0003] The spraying of inhibitors has great theoretical and practical significance for controlling and reducing the occurrence of major vicious accidents such as mine fires and gas explosions, especially for improving the mine's prevention of internal fir...
