Technical Field
[0001] The utility model relates to the technical field of coal mine gas extraction and sealing hole devices, in particular to a coal mine gas extraction and sealing hole device. Background Art
[0002] The coal mine gas extraction sealing device is a key equipment used for sealing gas extraction boreholes in coal mine safety production. Its main function is to ensure the sealing of the borehole during the gas extraction process, prevent gas leakage, improve gas extraction efficiency, and ensure the safety of mine operations. This type of device is usually installed after the drilling is completed to isolate the borehole from the surrounding coal and rock environment and create an effective extraction channel.
[0003] After searching, the patent number "CN219932120U" mentioned in the text that "the utility model provides a coal mine gas extraction and sealing device, including a casing, the interior of the casing is connected with a threaded column, one end of the threaded column is fixedly connected with a connecting plate, the inner side wall of the connecting plate is fixedly connected with a protrusion, the protrusion is embedded in the inside of the ring groove, and the ring groove is opened on the surface of the rubber pad. The utility model injects concrete into the injection head, the concrete is transported to the conveying trough through the through groove, and then transported from the conveying trough to the gas hole and the cavity of the casing, and then pushes the push rod so that the push plate compacts the concrete, and then presses against the push rod and waits for the concrete to solidify. When the concrete solidifies, the device can fully press the gas into the gas hole. The gas hole is blocked, and the gas extraction hole is completely sealed, thereby effectively preventing gas leakage. "When in use, the sleeve is inserted into the hole of the coal mine gas extraction hole, and then the threaded column is turned by hand. The threaded connection between the threaded column and the sleeve makes the threaded column drive the connecting plate to squeeze the rubber pad, so that the rubber pad is compressed. As the rubber pad is compressed, the size of the rubber pad will increase. As the size of the rubber pad increases, the rubber pad is squeezed on the inner wall of the gas hole, so that the gas hole can be sealed. However, the device needs to be operated manually. The manual operation device is not only time-consuming and labor-intensive, but also reduces work efficiency. In addition, the method of using concrete for sealing is backward, the sealing effect is poor, and it is easy to leak.
