DTH drilling equipment is designed for efficient drilling in hard and challenging rock formations. It is widely used for mining, quarrying, water wells, construction, and blasting holes. The hammer works directly at the bottom of the hole, delivering strong impact energy where it is needed most. YG offers several crawler mounted models with drilling diameters from 83 to 165 mm. If you need reliable drilling equipment for your project, contact YG for model selection, technical details, and a factory quotation. 【WhatsApp/WeChat/Skype/Phone】+86 159 3715 2330

DTH Drilling Equipment Applications Across Job Sites
A DTH rig is not limited to one type of project. Buyers use it across many job types.
Quarries and aggregate plants. Blast hole drilling in granite, limestone, and basalt.
Open-pit mining. Production holes and grade control drilling.
Water well drilling. Deep boreholes in hard rock formations.
Foundation and anchoring. Rock anchors, micropiles, and slope stabilization.
Road and railway construction. Pre-split and blast hole drilling.
Geothermal projects. Deep vertical holes for heat exchange loops.
One YG customer in Nigeria used two YGS180 rigs on a granite quarry. They cut drilling time per blast from 9 hours to 3.5 hours.

Real Overseas Cooperative Project Case
A Philippine mining engineering company purchased two sets of YGS350 dth drilling equipment in early 2026.
The project was focused on open-pit quarry blast hole drilling with hard rock stratum.
The YGS350 model with 73.5kw power stably maintained 90-165mm standard hole diameter.
Its 225L large fuel tank supported 12-hour continuous drilling without frequent refueling.
The overall drilling efficiency increased by 42% compared with their old traditional equipment.
The client shortened the whole project cycle and reduced fuel and labor costs obviously.
They have confirmed long-term cooperative intention for subsequent mining projects.

5 Practical FAQs About DTH Drilling Equipment
Q1: How to choose the right dth rig machine model?
Choose YGS153 lightweight model for small slope and shallow hole projects. Select YGS300 and YGS350 high-power models for large mines and hard rock drilling to ensure efficiency and stability.
Q2: What rock types can this down the hole drill rig handle?
It adapts to most common rock strata including granite, limestone, bluestone and weathered rock. It works stably in both soft broken stratum and high-hardness rock layers.
Q3: Is the crawler chassis adaptable to harsh working sites?
Yes. All YG models adopt professional engineering crawler chassis. It adapts to mountain roads, muddy ground and rugged construction sites with strong passing ability.
Q4: What is the daily maintenance method for DTH drilling rig?
Regularly check engine oil and hydraulic oil levels. Clean drill rod and impactor residues after operation. Inspect crawler tightness and bolt fastening to reduce failure rate.
Q5: Do you support customized configuration and after-sales service?
Yes. YG supports personalized configuration of power system and drilling accessories. We provide overseas installation guidance and after-sales technical support for all cooperative clients.
