Surface Exploration BQ 400m / NQ 300m / HQ 160m Crawler Type Core
Core drilling rig is a kind of core drilling equipment. It is
mainly used for the survey and exploration of metal and
non-metallic solid minerals. It can also be used for engineering
geological exploration, hydrogeological survey, oil and gas field
survey and exploration, and water well drilling.
TDC-300 full hydraulic core drilling rig is widely used in metal
mining, non-metallic mining and coal mining geological exploration
Also known as hydraulic rig, hydraulic rig is a rotary rig commonly
produced in China. The main types are rotary drilling rigs, impact
drilling rigs and compound drilling rigs.
It has great ability, the max hole depth it can drill is 400m, when
using NQ rod, the drill depth can reach 300m, when using HQ rod,
the drill depth can reach 160m.
The core drilling rig is composed of the basic parts such as the
slewing mechanism, the feeding mechanism, the lifting mechanism,
the transmission mechanism, the operating device and the machine
base. Due to the different types of rigs, some core rigs may also
be equipped with control gauges or other attachments. The slewing
mechanism of the rig is called a gyrator and is used to drive the
rig to rotate, so that the drill bit continuously breaks the rock.
Core rigs are available in vertical shaft, rotary table and mobile
type. The classification of core drilling rigs comes from this.
