Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a special drilling device for preventing and controlling water in coal mine tunnels. Background Art

[0002] Coal tunnels are various passages drilled between the surface and the ore body, used for ore transportation, ventilation, drainage, pedestrians, and various necessary preparatory works for the new excavation of ore for metallurgical equipment. Drilling or exploration is the use of deep drilling mechanical engineering technology to exploit underground or seabed natural resources, or to take actual profiles of strata and capture physical samples to provide experiments to obtain relevant data.

[0003] However, the existing drilling equipment cannot perform sampling synchronously during drilling, and sampling at a later stage reduces work efficiency. In addition, there are no components to block the rock and soil during drilling, and splashing will affect personnel. Therefore, a special drilling equipment for coal mine tunnel water prevention and control is needed to solve the above technical problems. Utility Model Content
