Best Underground Mining Trucks for Trackless Transport

Underground transportation is an essential part of metal and non-metal mining operations. Its scope covers ore handling and roadway transport, serving as the link between stopes, working faces, underground ore bins, backfill areas, and surface ore bins or waste dumps.

The design of underground mine transportation systems and methods is usually determined during the mine development stage. The key principles include adapting to deposit conditions, mining methods, production scale, service life, equipment development, and management capabilities. The goal is to achieve advanced and reliable technology, economic efficiency, operational safety, convenient management, low energy consumption, and reduced investment.

Trackless transportation in underground mining began in the 1960s. With the continuous improvement of underground trackless equipment, trackless mining technology has developed rapidly.

Underground mining trucks are specially designed vehicles for underground mines and serve as the core equipment for realizing trackless mining technology. These vehicles are mobile, flexible, versatile, and cost-efficient. They are widely used in suitable underground mines to strengthen production, improve labor productivity and output, expand production scale, and optimize mining methods and transportation systems.

In recent years, with the development of mine automation and intelligent mining systems, underground mining has been moving toward unmanned and highly efficient operations.

1. High flexibility and wide applicability – Underground Mining Trucks can transport ore directly from the working face to unloading sites without intermediate transfer. They can also deliver personnel, materials, and equipment directly to the working face.
2. Resource savings – Under certain conditions, the use of trucks reduces the need for additional equipment, steel, and labor.
3. Early ore output – Before shaft facilities are fully built, trucks make it possible to extract ore earlier and facilitate mining of marginal or scattered ore bodies.
4. Higher productivity – With reasonable haulage distances, the reduced number of operational stages significantly increases labor productivity.

While underground mining trucks have many benefits, they also present some challenges. Queen Machinery provides innovative solutions to overcome these issues:
(1) Exhaust Gas Pollution
Although underground trucks are equipped with exhaust purification devices, diesel emissions still affect air quality, requiring costly ventilation systems.

Queen Machinery Solution: Advanced exhaust water treatment technology, patented nationally, filters up to 60% of particulates and 50% of nitrogen oxides through triple filtration, ensuring a cleaner underground environment.

(2) High Tire Consumption
Poor underground road conditions increase tire wear, leading to higher spare parts costs.

Queen Machinery Solution: All trucks are equipped with specialized 14-ply steel radial tires (R series), which perform well in harsh environments and are more durable than traditional nylon bias tires.

(3) Maintenance Demands
Frequent use requires skilled technicians and well-equipped workshops.

Queen Machinery Solution: Certified nationwide for after-sales service standards, the company offers a comprehensive service system and customer training, ensuring prompt and reliable support.

(4) Larger Roadway Cross-Section Requirements
Trucks often require larger tunnel profiles, which increases development costs.

Queen Machinery Solution: Compact and robust designs tailored for low-profile tunnels. With over a decade of craftsmanship and customization experience, Queen Machinery delivers efficient, size-adjusted solutions to meet customer needs.
