Abstract

The invention provides a fire prevention and extinguishing linear glue injection method. The method comprises the following steps of: determining a spontaneous combustion position according to spontaneous combustion information; determining a construction position and a drilling direction of a drill hole, a plurality of glue injection positions in the drilling direction and corresponding glue injection amounts at the glue injection positions according to the spontaneous combustion position; obtaining the drill hole through construction; mounting a glue injection sleeve with a glue injection end on the drill hole; moving the glue injection end to the glue injection positions respectively; and injecting glue. According to the fire prevention and extinguishing linear glue injection method, the glue is injected at the glue injection positions in the drilling direction, so that the glue can directly cover and extinguish an ignition point, or a glue isolation belt is formed at an estimated position of the ignition point and near the estimated position, and furthermore, oxygen near the ignition point is reduced, and the aim of suffocating the ignition point is realized. The linear glue isolation belt can be formed by only operating one drill hole, so that the problem of low efficiency in fire prevention and extinguishing treatment in a point type glue injection manner in the prior artcan be solved.

Description

technical field [0001] The present application relates to the field of fire prevention and extinguishment in coal mines, in particular to a linear glue injection method for fire prevention and extinguishment. Background technique [0002] The natural fire in the closed goaf of the mine is one of the main disasters faced by the mine space. Since the mine space is relatively small, once a fire breaks out, it will not only make it difficult for the staff to escape, but also cause harm to the environment due to the high temperature and a large amount of toxic and harmful gases. The health of the staff requires fire prevention and extinguishing treatment for the closed goaf. [0003] At present, mines mostly use the method of drilling first, then installing a rubber injection sleeve in the drill hole, and then injecting colloid into the closed goaf through the rubber injection sleeve to prevent fire. However, this injection method is Point-type glue injection, under normal circu...
