Project Overview: YG Excavator Drill and Splitting Machine Deployed in Bulgaria
Bulgaria’s infrastructure sector is expanding rapidly, with major investments in road networks, tunnel construction, and mining operations across the country. A Bulgarian civil engineering contractor secured a rock excavation project in the Stara Planina mountain region, requiring efficient rock breaking without traditional blasting methods.
The contractor selected our integrated drill and splitting machine – a hydraulic rock drill and splitter mounted on a 25-ton excavator. This machine arrived on-site in Q1 2026 and has been operating continuously for over 6 months.
Technical Specifications of the Integrated Drill and Splitting Machine
The following parameters define the hydraulic rock drill and splitter delivered to the Bulgarian project:

Excavator requirements:>20T
This integrated drill and splitting machine combines drilling and splitting into a single attachment. The machine first drills a 120mm diameter hole to 1600mm depth at 1m/min, then rotates 120° to position the splitter for 8000T splitting force. The entire sequence is completed without repositioning the excavator.
Site Conditions and Challenges for the Excavator Drill and Splitting Machine
The Bulgarian project involved excavating hard granite with compressive strength reaching 80MPa. The site presented several challenges:
Hard rock formation – granite with high compressive strength
Restricted area – proximity to an active roadway prohibited blasting
Environmental requirements – strict noise and vibration limits
Limited working space – narrow mountain terrain
Traditional blasting was not permitted. The contractor needed an integrated drill and splitting machine that could deliver precise, controlled rock breaking with minimal environmental impact.

Why Does YG Hydraulic Rock Drill and Splitter Suit Bulgarian Conditions?
The machine offers several advantages for Bulgarian rock excavation:
No blasting required – The machine eliminates explosive permits and safety zones. This is critical for projects near roadways and populated areas.
Single-machine operation – This machine performs both drilling and splitting, reducing equipment fleet requirements.
Precision control – The integrated drill and splitting machine provides accurate hole placement and controlled splitting direction.
Environmental compliance– Low noise and minimal dust meet Bulgarian environmental standards.
Wear parts on the machine – including copper sleeve, shank, drill rod, drill bit, splitting wedge, and wedge block – are not covered under warranty and require regular inspection.
The Bulgarian contractor reports that routine maintenance of the machine takes approximately 2 hours per week, with major service intervals at 300 and 1000 operating hours.
Hydraulic Rock Drill and Splitter Delivers Results
The machine has proven effective for Bulgarian rock excavation. Key outcomes after 6 months:
Drilling speed – 1m/min through 80MPa granite
Splitting force – 8000T capacity handles large rock masses
Depth capacity – 1600mm drilling depth with 1000mm splitting depth
Operational efficiency – single machine replaces multiple equipment pieces
For Bulgarian contractors facing hard rock excavation without blasting options, YG’s integrated drill and splitting machine offers a proven solution.
