Abstract | The invention relates to a method for treating local coal mine gas accumulation on an excavating working surface using methane-oxidizing bacteria, and belongs to the technical field of coal mine localgas prevention and treatment. The method comprises the steps that the methane-oxidizing bacterial fluid and yellow mud are mixed with air to form a three-phase viscous state, the methane-oxidizing bacterial fluid and the yellow mud are smeared on a coal wall where the coal mine gas accumulates, coal mine gas accumulating holes are drilled in the part where excessive coal mine gas surges, a bacterial fluid bearing frame is produced, three-phase bacterial fluid is smeared in the hole, methane-oxidizing bacterial fluid is added to a bacterial fluid groove in the bacterial fluid bearing frame, and the problem of local coal mine gas accumulation is solved from multiple levels. The method has the advantages the defects of an biological coal mine gas treatment technology are overcome, innovationto a higher extent is ach |
