What is the difference between electric and pneumatic models?

The electric model uses an electric motor to power the rotary system, while the pneumatic model uses an air motor. Both configurations use compressed air to drive the DTH hammer.

Which model is suitable for a 100 mm blast hole?

The YG100 or YG130 is generally suitable because both support drilling diameters of 65-130 mm. The final selection depends on the required depth and rock hardness.

Product Q&A

Q:What is a DTH drilling rig?

A DTH drilling rig is a rock drilling machine that uses a down-the-hole hammer located directly behind the drill bit. Compressed air drives the hammer to strike the bit while the rotary unit rotates it.

Q:What materials can this drilling rig handle?

It is mainly designed for medium-hard and hard rock with a Protodyakonov hardness coefficient of f = 8-20. Suitability should be confirmed according to the actual geological conditions.

Q:What is the available drilling diameter?

Depending on the model, the drilling diameter ranges from 55 mm to 180 mm.

Q:What is the maximum drilling depth?

The YG70 drills to approximately 15 m or more, while the YG150 can reach 40 m or more under suitable geological and operating conditions.

Q:Does the machine require an air compressor?

Yes. The DTH hammer requires compressed air for impact operation and borehole flushing. The required compressor capacity depends on the selected model.
