The drilling rig is the main engine to complete the drilling construction. It drives the drilling tool and the drill bit to deep into the formation, and uses the elevator on the drilling rig to complete the auxiliary work such as lifting the drilling tool and casing, extracting the core, and replacing the drill bit. The main function of the pump is to deliver flushing fluid into the hole to clean the bottom of the hole, cool the drill bit and lubricate the drill tool. The purpose and construction objects of rock and soil drilling and tunneling are different, so there are many types of drilling rigs. Drilling rigs can be classified by purpose, such as core drilling rigs, oil drilling rigs, hydrogeological survey and water well drilling rigs, engineering geological survey drilling rigs, tunnel drilling rigs and engineering construction drilling rigs. According to drilling methods, drilling rigs can be divided into four categories:

(1) Impact drilling rigs: wire rope impact drilling rigs, drill pipe impact drilling rigs.

(2) Rotary drilling rig: vertical shaft type--handle feed type, spiral differential feed type, hydraulic feed type drilling rig; rotary table type--steel rope plus decompression type, hydraulic cylinder plus decompression type drilling rig; mobile Rotator-full hydraulic power head type, mechanical power head type drilling rig.

(3) Vibration drilling rig.

(4) Compound drilling rig: A drilling rig with functions such as vibration, impact, rotation, static pressure and so on in different combinations.
