In the fields of mineral exploration and geological surveys, choosing the best drill rig for hard rock layers is crucial to the success of a project. Hengwang Group's independently developed HW-YDX-1500GL fully hydraulic core drill rig, with its superior penetration power and intelligent control system, has become the preferred equipment for global hard rock exploration. This article will analyze why this rig is acclaimed as the best drill rig for hard rock layers and highlight its core technical advantages.

I. Why is the HW-YDX-1500GL the Best Drill Rig for Hard Rock Layers?

Powerful Drive System

1. Equipped with a Yuchai 162kW six-cylinder turbocharged engine for stable power output

2. 2500N·m ultra-high rotary torque, effortlessly handling granite, basalt, and other hard rock layers

3. Two-speed motor enables seamless switching between low-speed high-torque and high-speed high-efficiency modes

Deep Drilling Capability

1. Maximum drilling depth of 1500m (leading in its class)

2. Uses BQ/NQ/PQ standard drill rods with 3m single lengths to reduce rod-changing frequency

3. 30-ton hydraulic lifting force ensures safety in deep-hole operations

Precision Control System

1. Digital angle adjustment (±90° adjustable) ensures accurate drilling trajectory

2. Real-time monitoring of drilling pressure and rotation speed, automatically adapting to rock hardness

3. Shock-absorbing sliding spindle reduces core breakage rate

II. Differentiated Advantages of the HW-YDX-1500GL

Fully Hydraulic Intelligent Operation

1. Hydraulic side-shifting legs allow ±30° fine-tuning, suitable for narrow mining areas

2. 1.5m-high leg design adapts to slope operations (maximum 25° inclination)

Composite Drilling Technology

1. Dual-mode switching between percussion and rotation for fractured rock formations

2. 250L/min high-flow mud pump effectively cools the drill bit

Modular Design

1. Total weight of only 12 tons, disassemblable into 6 modules for transport

2. Compact dimensions (6300×2200×2400mm) suitable for underground operations

III. Proven in Global Hard Rock Projects

African Copper Belt Exploration

1. Completed ultra-deep drilling: 76mm diameter, 1426m depth

2. Core recovery rate of 91.3% (6.3% above contract requirements)

Chilean Lithium Salt Lake Sampling

Maintained an average speed of 7.2m/hour in grade-7 evaporite rocks

Southeast Asia Tunnel Geological Forecasting

Precisely controlled 15° inclined borehole with less than 0.5‰ error

IV. Three Key Factors in Choosing the Best Drill Rig for Hard Rock Layers

1. Power Reserve:Torque and lifting force determine hard rock penetration capability

2. Control System:Digital precision impacts sampling quality

3. Field Case Studies: Actual project data matters more than specifications
