Description

Coal Mine Crawler Tunnel Drilling Rig with Detachable Drill Pipe

technical field

The utility model relates to a crawler-type tunnel drilling machine and a use method thereof, in particular to a crawler-type tunnel drilling machine for coal mines with detachable drill rods and a use method thereof.

Background technique

Coal occupies a dominant position in my country's energy composition. However, the environment of coal production is extremely harsh, and major disasters and accidents occur frequently. Among them, gas and coal dust explosion disasters are one of the main forms of coal mine disasters in my country. Among them, the main hazards of gas explosion and coal dust explosion are shock wave, flame front and a large amount of harmful gas. Once the gas explodes, it will cause a large number of underground casualties and material property losses, seriously restricting the safe production of coal mines in our country.

The crawler tunnel drilling rig is one of the important equipments to realize the mechanization and modernization of coal mine production. Mechanized drilling can reduce physical labor, improve safety, and achieve high output, high efficiency, and low consumption.

The crawler tunnel drilling rig is suitable for gas and high gas mines. It can construct large-diameter gas drainage boreholes, such as pre-drainage boreholes in the coal seam or gas drainage boreholes in goafs, etc. Compared with similar units, it has high production efficiency, strong reliability, low failure rate and good safety Advantage. Utilizing the crawler tunnel drilling rig can improve the efficiency of gas drainage, reduce the economic investment in gas control, and improve the overall benefit of the mine. It has high economic and social benefits, and is a popular product for large-diameter drilling.

The crawler tunnel drilling rig adopts the single-head drilling process. The main engine is arranged in the trough, and the hydraulic propulsion device is used to drive the rotating drilling tool to drill holes in the side coal seam. The drill bit cuts the coal, and the auger pipe discharges the coal. The groove is transported out on the scraper machine to realize safe drilling.

With the development of new technology and new technology, coal mine underground gas drilling rigs are developing towards large-scale, intelligent and humanized directions. The current situation of my country's coal mine underground drilling rigs is that the diameter of ordinary drilling rigs is generally below 150mm, and the length of the drill pipe is generally 1-2 meters, because the diameter of the drill pipe is relatively small, the overall weight of the drill pipe is relatively light, and generally 1-2 people can carry it. However, with the continuous increase in coal mine production requirements, large-diameter drilling has become an inevitable development of drilling rigs trend.

The common disadvantage of large-diameter drilling rigs is that the drill pipe is heavy. Taking the helical drill pipe with a diameter of 400mm and a length of 800mm as an example, the total weight of one piece is 120kg-200kg, and it is difficult for two people to load and unload the drill pipe. At present, the method of installing hanging anchors on the roof is generally adopted underground, and the manual hoist is used for handling and installation. The position of the anchor may conflict with the original support position; it is inconvenient to use a manual hoist, because the manual hoist is limited by the working environment, and it needs to be disassembled frequently, which delays the production progress; Due to the limitation of the position and the manual hoist, it is difficult to realize the fast and accurate docking of the drill pipe and the drill pipe.
