Portable DTH Water Drilling Rig is applicable to small and medium-sized mines and road construction, defense and water conservancy and stone works for large borehole drilling.
It’s also an indispensable rock drilling facility for open pit mining, especially on the rugged mountain slope where other drilling vehicles can't work normally.
The main advantages of portable drilling rig are as follows:
Compact structure, easy operation, quick cutting speed, high efficiency, good demolition, convenient transport;
The energy loss does not increase with the drill pipe increasing;
Working noise is greatly reduced;
Higher degree of mechanization, less auxiliary operation time, improving the drilling rig operating rate.
