Technical Field

The invention relates to the technical field of mine gas emission, in particular to a novel rapid hole packer.

Background

In the tunneling process, the gas content fluctuation in a local area is abnormal due to the fact that the gas holes are cut off, particularly under the condition that a drainage drill hole is a long hole, the gas holes are cut off more frequently, the gas holes are cut off in the shortest time in a pumping mode, and the method is very critical to preventing the gas from exceeding the limit and ensuring safe production.

The known hole sealing of the coal mine gas drainage hole is to insert a drainage pipe into the coal mine gas drainage hole and then seal the periphery of the pipe by cement mortar or polyurethane.

Most of rapid hole packers in the existing market often have the problems of complicated working procedures, many operating devices, inconvenient actual operation and the like, cause certain potential safety hazards to a working area, cannot timely control gas, and easily cause special conditions such as large gas emission quantity in the working area. Therefore, a novel rapid hole packer is provided.
