AZD295 Double Boom Drilling Jumbo: High-Efficiency Tunnel & Mining Drilling Solution

Introduction

Tunnel excavation and underground mining projects demand drilling equipment that balances high efficiency, stable performance, and strong site adaptability. Traditional single-boom drilling rigs struggle to meet fast-paced construction requirements for medium and large tunnel sections. The AZD295 Double Boom Drilling Jumbo is professionally engineered to solve this pain point, delivering dual-boom high-output drilling, wide coverage, and reliable all-terrain performance for modern tunneling and mining operations.

Ideal for highway tunnels, railway tunnels, hydropower caverns, subway engineering, and underground mineral mining, the AZD295 has become a core efficient drilling solution for medium-sized underground construction projects worldwide.

AZD295 Double Boom Drilling Jumbo Overview

The AZD295 is a full hydraulic crawler double-boom drilling jumbo optimized for medium cross-section tunnel excavation. Equipped with two independent high-power rock drills, the machine supports simultaneous dual-hole drilling, greatly shortening construction cycles and improving overall project efficiency.

With a maximum working coverage of 120㎡, it covers most conventional medium tunnel sections in one single positioning. It can complete blast hole drilling, anchor hole drilling, and cut hole drilling, realizing multi-functional one-machine operation.

Core Technical Parameters

Key Features & Competitive Advantages

1. Dual-Boom Synchronous Drilling, Double Efficiency

Equipped with two sets of independent high-power rock drills, the AZD295 supports simultaneous drilling operations. The four-direction parallel positioning system ensures accurate hole arrangement, effectively reducing single-cycle drilling time and greatly improving tunnel blasting and tunneling progress compared with single-boom rigs.

2. High-Rigidity Drill Boom & Wear-Resistant Structure

Adopts high-rigidity square drill booms with built-in wear-resistant copper guide plates. The structural stability effectively resists drilling vibration and rock impact, reducing component wear and extending the overall service life of the drilling system.

3. Lightweight High-Strength Aluminum Alloy Feed Beam

The feed beam uses aviation-grade aluminum alloy material, which is lightweight, high-strength, corrosion-resistant, and not easy to deform. It ensures flexible drilling action while adapting to humid and dusty underground working environments.

4. Euro IV Emission Engine & Strong Mobility

Powered by a 162kW four-wheel drive diesel engine that complies with Euro IV and National IV emission standards. It delivers strong power output, fast response, and excellent climbing performance of up to 40%, adapting to steep slopes and uneven tunnel road conditions. Equipped with spring brake and hydraulic release system, the machine ensures safe and stable traveling and parking in complex underground working scenarios.

5. Intelligent Load-Sensing Hydraulic System

The AZD295 adopts an upgraded load-sensing proportional hydraulic system, which automatically adjusts impact power and feed speed according to different rock hardness. It avoids ineffective energy consumption, reduces equipment heat generation, and improves overall working efficiency. The optional electro-hydraulic proportional valve simplifies operation and lowers daily maintenance costs.

6. International-Grade Electrical Safety Configuration

All core electrical components adopt well-known international brands such as Siemens and Schneider. The system is equipped with complete protection functions including leakage protection, phase sequence protection, motor overload protection and engine fault alarm, effectively avoiding equipment failure and safety accidents, ensuring long-term stable operation of the machine.

Main Application Scenarios

The AZD295 double boom drilling jumbo features wide coverage, high efficiency and strong adaptability, and is widely used in various underground engineering fields:

• Traffic Tunnel Engineering: Highway tunnels, railway tunnels, subway tunnels
