Tunnel drilling rig refers to the drilling rig used to drill in the underground roadway of the mine Secondary specialized school the geological survey drilling project. Tunnel drilling rig is mainly used for deep geological exploration, gas drainage, injection and drainage, ventilation, etc. The tunnel drilling rig has the characteristics of good disintegration, light weight of each component, and the drilling direction can be 0 ° ~ 360 °. The range is conveniently adjusted. According to the use of power, it can be divided into vertical shaft type (including spiral differential feed) and power head type (mechanical and full hydraulic). The driving mode can be pneumatic, hydraulic and electric. The main components of the drilling rig are power machine (group), gyrator, drilling tool pulling mechanism, drilling.

The main components of the drilling rig include power machine (group), gyrator, drilling tool pulling and feeding mechanism, and drilling tool screwing and unloading device. Generally, the drilling tower (mast) is not provided. Drilling rigs are usually fixed to work on a single-leg or double-leg column.
What are the commonly used tunnel drilling rig models?
Tunnel drilling rigs are divided by moment. The most commonly used models are:ZDY3200S, ZDY4000S, ZDY4000L, ZDY6000L, where ZDY stands for full hydraulic drilling rigS stands for double pump system, L stands for crawler;
