Description

[0002] 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, gradually accumulate into thick layers in a suitable geological environment, and are buried in water or mud. It is formed by natural coalification over a long geological period. Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. The scope of a coal mine includes a large area above and below the ground and related facilities. It is a reasonable space excavated by humans when digging geological layers rich in coal, usually including tunnels, shafts, and mining faces.
[0003] At present, in the process of using anchor rods in existing coal mines, after the anchor hole is drilled, it is necessary to inspect the anchor hole to ensure that the drilling depth of the anchor hole is in place and there is no obstruction on the inner wall of the anchor hole, and then the anchor rod is driven in for positioning. The traditional inspection and cleaning method is to extend the drilling drill into the anchor hole again and drill the anchor hole again. However, the secondary drilling is likely to cause secondary damage to the inner wall of the anchor hole, so there is still the possibility of impurities and obstacles falling into the anchor hole, affecting the positioning efficiency of the anchor rod.
