- Coal Mine Tunnel Drilling Rig
- Mining Tunnel Water Exploration Drilling Rig is mainly used for rotary drilling inside mines and can drill up to - meters to meet the needs of different customers.
Drillable water drainage holes, geological structure holes, fire extinguishing holes, drainage, etc. and other drilling projects can also be worked on the ground.
-The tunnel drilling rig for coal mines adopts mechanical transmission and hydraulic feed structure, which is simple in size, small in size, light in weight, easy to operate and reliable in performance. The drilling rig is equipped with a hydraulic chuck and a hydraulic feed cylinder. Use standard automobile transmission, clutch, reliable performance, flexible operation and low cost of accessories.
The overall box structure has the advantages of high transmission efficiency and full-section drilling. It can drill holes at any angle in rock formations with different hardness, but it is most efficient when drilling in coal seams, soft rocks and medium-hard rocks.

-type tunnel drilling rig is used in the general survey and exploration of mineral deposits, especially in the general survey and exploration of non-ferrous metals and rare metals, etc. Tunnel drilling is used to trace mineral deposits, intensify exploration, survey geological structures, delineate ore bodies, and sample and verify. Tunnel drilling technology is commonly used in mine excavation to drill underground observation holes, -type tunnel drilling rig ventilation holes, drainage holes, discharge holes, grouting holes, blasting holes, anchor holes and pilot holes for tunnel excavation. The -type tunnel drilling rig's tunnel drilling equipment and technology in other geotechnical engineering construction fields can be used for slope reinforcement of dam foundations, control of geological disasters, support of deep foundation pits, and underground engineering construction in industrial, commercial, and transportation areas.
- When the well depth is large (above meters), the chip removal capacity of the tunnel water exploration drilling rig is greater than that of drilling rigs that use pump suction or jet reverse circulation. Therefore, it is suitable for situations with large well depths, arid areas lacking water, and cold frozen soil strata. .
Precautions when using tunnel drilling rigs
During operation of the machine, electrical insulation conditions and wiring should be checked regularly to see if they are loose!
. The vertical shaft is not allowed to rotate when the spring chuck is in the released state!
. Every time you start, you should check whether the direction of rotation of the motor is correct, whether the rotation of the water feeder is
flexible, and whether the water delivery hose is flexible. Secure to prevent loosening!
