There are two main DTH types: pneumatic and electric. The dth drilling machine with pneumatic drive has a higher dynamic force and can reach greater depths. The electric type is lighter and easier to carry on site. Choose by hole depth and how often you move the rig.
YG rigs have many useful features. The hydraulic option gives steady power for hard work. The small DTH drill rig version is very stable and efficient. Its benefits are easy to see:
Light And Flexible: Move the rig by truck or trailer. Works in mountains and narrow tunnels.
High Penetration Power: DTH hammer breaks hard rock fast.
Energy Efficient: Good drilling per liter of fuel or per kW of power.
Long Life Parts: Alloy drill rods and hard-wearing bits reduce downtime.
Easy to Operate: Clear controls and simple maintenance.
These features reduce cost per hole and raise weekly output. The hydraulic drive helps keep pressure steady on tough jobs.
Application of Portable DTH Drill Rig
The Portable DTH Drill Rig fits many work types. Typical uses are:
Mining Work: Hard rock drilling, pre-splitting, and exploration holes.
Tunnel Construction: Drilling holes for anchors, bolts, and reinforcements.
Foundation and Ground Work: Anchor holes, soil nailing, rock socket drilling.
Energy Projects: Foundation holes for wind towers and solar mounting in rocky sites.
The rig works where heavy rigs cannot go. It cuts time and keeps the site safer by reducing blasting needs.
For small jobs and quick moves, the small portable drilling rig is a top pick. It is lightweight and easy to set up. Use it for:
Short drilling campaigns in remote pits.
Quick anchor or bolt holes for tunnel crews.
Jobs where space is limited and speed matters.
A small rig needs fewer workers and can be put to work within hours. It is ideal when crews need fast mobility and low cost.
Customer Cases
A mining client in Africa used YG portable rigs with a rock splitting tool. Their team replaced traditional blasting with the rig and splitter. The results were strong and clear:
Project Cost Down: total cost reduced by 25% vs blasting.
Work Speed Up: drilling and split operations were 30% faster.
Safer Site: no blasting, less vibration, lower safety risk.
Customer Feedback: “The portable DTH rig worked well in rough ground. We saved money and time. Crews learned the controls quickly.” This case shows real gains in cost and safety.
Full service: installation help, spare parts, and training.
YG rigs come with clear manuals and remote support. We also supply training so crews use the rig safely and well.
How To Choose The Right Rig
Pick a model by answering three simple questions:
How deep are the holes? Deeper holes need larger pneumatic DTH rigs.
How often will you move the rig? Many moves favor electric/light models.
What is your fuel and power source? Diesel is common for remote mines; electric suits sites with power.
