At a limestone quarry in Oman, the customer faced the practical need for safe and precise excavation on steep slopes. Traditional blasting methods not only involve complex approval procedures but can also compromise the integrity of the ore body and operational safety. The drilling and splitting machine provided by YG Machinery, with its suitable technical features, offered a viable alternative to blasting for this project, presenting the customer with a feasible solution.【WhatsApp/WeChat/Phone】+86 13837122632
Project Background and Practical Requirements
The mining operation faced several specific challenges:
- Terrain Limitations: The significant slope gradient placed higher demands on equipment stability and safety during operation.
- Precision Requirements: The customer needed to minimize internal damage to the raw limestone blocks to increase the yield rate of high-quality stone.
- Efficiency Needs: There was a desire to find a more continuous and controllable extraction method than traditional approaches to stabilize production pace.
The Solution – YG Excavator Rock Drill and Splitter
To address the site conditions, we recommended the YG-130 integrated rock drill and splitter (compatible with 20T-36T excavators). This equipment integrates drilling and splitting functions, is powered by the excavator’s hydraulic system, and is suitable for mechanized, continuous operation in such terrain.

Adaptability and Performance of the Drilling and Splitting Machine
During on-site application, this excavator rock drill and splitter demonstrated its design features:
- Good Working Condition Adaptability: The equipment’s center of gravity design accounts for operational balance, helping the excavator maintain stability on slopes for safe drilling positioning.
- Practical Operational Capability: The machine can perform multi-angle drilling, meeting construction requirements for hole direction on steep slopes.
- Effective Static Splitting: Its hydraulic splitting system generates sufficient static force to fracture rock from within, reducing vibration and damage to the surrounding rock mass.
Project Application Results
After adopting YG’s drilling and splitting machine, the project made tangible progress in several areas:
- Improved Construction Safety: Blasting operations were avoided, reducing associated safety risks and approval procedures.
- Enhanced Extraction Quality: The static splitting method facilitates rock separation along more desirable lines, offering better protection for block integrity.
- Increased Operational Efficiency: The equipment enables continuous cyclic work. According to customer feedback, overall extraction efficiency improved compared to previous methods.
Basis for the Reliability of the Drilling and Splitting Machine
The stable performance of the equipment in the project is attributed to several fundamental design aspects:
- Structural Design: Manufactured using high-strength steel plates, it balances structural strength with weight control.
- Core Components: The use of alloy drill bits ensures drilling capability, and the hydraulic system is equipped with overpressure protection for enhanced stability.
The case of the Omani limestone quarry demonstrates that YG’s rock drill and splitter can provide a practical technical option for specific mining conditions. We are committed to offering suitable drilling and splitting machine configurations and application support based on the actual on-site conditions of our customers.
