DTH Drilling Rig is a borehole drilling rig, hydraulic crawler type, it is used in an open pit mine
DTH Drilling rig is used for drilling boreholes in the stone. It is not like water well drilling that can drill hundreds of depths into the ground, Crawler Hydraulic type Borehole DTH Drilling Rig usually drills around 30m in depth. Two steel track makes it powerful in walking in the mountainous area, if required, it can be rubber tracks.
The diesel engine of Crawler Hydraulic type Borehole DTH Drilling Rig is commins or yuchai. They are a famous brand over the world. The diesel engine can be two cylinder and four cylinder, which depends on the needs.
The rotary power source of the Crawler Hydraulic Borehole DTH Drilling Rig is from a screw air compressor, the compressed air is sent to the impact device and it breaks the rick into pieces while drilling. And some may call it a pneumatic drilling rig, for it uses air to drill.
Crawler Hydraulic type Borehole DTH Drilling Rig is very flexible, it can drill horizontally boreholes and vertical boreholes. And the skid beam can swing to the left or right. This is what makes it different from a water well drilling rig.
The borehole diameter is 110-203mm
Max. Borehole depth is 60m
Working air is 0.7-2Mpa and the air usage is 8-20m3/min
The rotation speed can be changed according to the needs
The hydraulic system of Crawler Hydraulic type Borehole DTH Drilling Rig is advanced, it is powerful in drilling boreholes.
According to the needs you can choose a dust collector to keep the working clean.
