Drilling rig

Product Overview

This drilling rig is a high-efficiency drilling unit designed for hard-rock mining operations. Integrating rod feeding, rotary drilling and impact drilling into a single operation, it delivers a maximum hole diameter of 150mm and is widely applicable to open-pit mining, overburden stripping and underground production operations. The wheeled off-road chassis ensures rapid relocation across complex terrain, while the guide and alignment system guarantees drilling accuracy, providing mining customers with a high-efficiency, low-cost integrated drilling solution.

Challenges Faced by Mining Customers

1. Low drilling efficiency and long production cyclesTraditional rigs feature single-function design, requiring separate operations for rod feeding, rotary and impact drilling, resulting in long per-hole time that cannot meet the production rhythm of large-scale mines.

2. Poor adaptability to hard-rock conditionsHighly abrasive hard rock such as granite and iron ore imposes stringent requirements on rig performance. Conventional equipment suffers from low penetration rates and high failure rates in hard rock, and struggles to operate on benches with significant elevation changes in dry, dusty environments.

3. Large hole deviation and poor blasting resultsDeviation in hole position and angle causes uneven blasting, high oversize fragmentation rate, extensive secondary breaking requirements, increased explosive consumption, and heavier workload for subsequent loading, hauling and crushing operations.

4. Difficult relocation and inflexible deploymentRigs requiring dismantling for transport consume excessive time and labor when moving between benches, making it difficult to quickly adjust deployment as the mining face advances, thus affecting production continuity.

5. High maintenance cost and long downtimeNon-standardized spare parts have long procurement cycles and high prices, and equipment failures cause extended downtime. Meanwhile, traditional rigs rely on manual operation, requiring more on-site personnel and incurring high labor costs.

Solutions and Core Advantages

1. Integrated High-Efficiency Drilling, Significantly Shortening Operation CyclesThe rig integrates three core functions — rod feeding, rotary drilling and impact drilling — into a single operation flow, achieving high-speed penetration per hole. With a maximum hole diameter of 150mm, it supports large-diameter deep-hole operations and efficiently completes multiple blast holes, significantly reducing the overall drilling cycle and perfectly matching the high-efficiency requirements of large-scale open-pit mining, overburden stripping and production operations.

2. Dual-Purpose for Open-Pit and Underground, Full-Condition Hard-Rock AdaptabilityThe equipment is suitable for both open-pit and underground mining, handling various rock formations including granite, iron ore and other highly abrasive hard rock. It maintains efficient operation on open-pit benches with significant elevation changes and achieves continuous, stable operation in dry and dusty environments. One unit covers multi-scenario operation requirements, reducing capital investment cost.

3. Precision Guide and Alignment, Enhancing Overall Blasting BenefitsEquipped with a drill rod guide and alignment system, it effectively controls hole deviation, ensuring high compliance between actual and designed hole positions and drilling angles. Consistent blast-hole quality improves blasting performance, reduces oversize fragmentation, minimizes secondary breaking requirements, lowers unnecessary explosive consumption, and simultaneously reduces the workload of subsequent loading, hauling and crushing processes, achieving cost reduction and efficiency improvement across the entire workflow.

4. Wheeled Off-Road Chassis, Flexible Mobility and Rapid DeploymentFeaturing a wheeled configuration with excellent off-road mobility, the rig can move directly between working benches without frequent dismantling or transportation. As the mining face advances, the rig can be easily relocated to follow the mining sequence and precisely match the production schedule, ensuring the continuity and flexibility of mining production.

5. Standardized Spare Parts + Optional Automation, Controllable Life-Cycle CostThe entire machine uses standardized, readily available common spare parts, effectively controlling maintenance costs and downtime. Improved drilling quality delivers better blasting results and reduces the workload of subsequent loading, hauling and crushing operations. The automated version further reduces operator workload and decreases the number of on-site personnel, maximizing comprehensive production benefits from three dimensions: equipment maintenance, production efficiency and labor cost.
