Product Q&A
Q:What is a DTH drilling rig?
A:
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?
A:
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?
A:
Depending on the model, the drilling diameter ranges from 55 mm to 180 mm.
Q:What is the maximum drilling depth?
A:
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?
A:
Yes. The DTH hammer requires compressed air for impact operation and borehole flushing. The required compressor capacity depends on the selected model.
