Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a combined collapsed hole failure drilling repair device in an underground coal mine. Background Art

[0002] Coal mines are areas where humans exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine. Coal is the most important solid fuel and a type of combustible organic rock. It is formed by lush plants that grow in a certain geological age. In a suitable geological environment, it gradually accumulates into thick layers and is buried under water or mud. It is formed by natural coalification over a long geological period. According to the degree of coalification, coal can be divided into four categories: peat, lignite, bituminous coal and anthracite. With the development of society, when the boreholes in coal mines need to be repaired, collapsed hole failure drilling repair devices are used.

[0003] The inventor discovered in his daily work that workers place a collapsed hole repair device in a collapsed borehole and start the collapsed hole repair device so that the collapsed hole repair device can clear the blocked soil by jetting water. However, during the preparation work, workers need to combine protective components. Because they are affected by light and space, the workers may encounter problems such as easy slipping of the protective components and difficulty in installation during the installation process.

[0006] Preferably, the surfaces of the two slides close to one end of the baffle are fixedly connected with a sleeve plate, the two sleeve plates are sleeved on the surface of the sleeve ring, and the two sleeve plates are sleeved on the surface of the water spray pipe. The sleeve plate can cooperate with the slide to achieve the purpose of limiting the sliding of the sleeve ring.

[0008] Preferably, a placement ring is fixedly connected to the surface of the rotating block, and the placement ring is located above the water spray pipe. The placement ring can cooperate with the rotating block to achieve the purpose of supporting and adjusting the placement ring.

[0009] Preferably, the inner surface of the placement ring is threadedly connected with an extrusion rod, and the extrusion rod is located above the water spray pipe. The extrusion rod can cooperate with the placement ring to achieve the purpose of guiding the extrusion rod.
