[0002] Coal mine gas extraction is to drill into coal seams and gas concentration areas, connect the boreholes to special pipelines, and use extraction equipment to extract the gas in the coal seams and goaf to the ground for utilization or discharge it into the total return air flow.

[0003] Gas extraction can not only reduce the amount of gas outflow during mining, prevent gas over-limit and accumulation, but also is an important measure to prevent gas explosions and coal and gas outburst accidents. It can also turn harm into benefit and be developed and utilized as a resource associated with coal. Since various pipelines are laid in the tunnel, they cannot be laid flat on the ground. Laying pipelines on the ground has safety hazards. In order to make rational use of the tunnel space, a more reasonable way is to lay the gas extraction pipe on the tunnel roof. Since the laying environment of the gas extraction pipe is complex and changeable, in order to achieve a better laying effect, the fixing device needs to be able to fine-tune the position. Based on this need, a practical gas extraction pipe fixing device is designed. Utility Model Content

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] 1. The utility model has a scientific and reasonable structural design, strong practicality, and is easy to install. The fixed position of the gas extraction pipe can be adjusted by adjusting the positions of the left fixing member and the right fixing member in the slide groove. The overall clamping and fixing of the gas extraction pipe is completed by the third screw and the fourth screw. The clamping is stable, flexible, practical, and can be promoted for use.

[0011] 2. The utility model directly clamps and fixes the gas extraction pipe by means of the clamping and fixing layer. When the gas pressure is too high, the gas extraction pipe will produce a small vibration, and the shock-absorbing buffer layer will be used to buffer and unload energy, thereby ensuring overall safety and stability.
