Solving Underground Mining Haulage Challenges with an LHD Loader and Mining Dumper Truck in Africa

31 August, 2026

Efficient underground material handling depends on the right combination of loading and hauling equipment. For African underground mining projects, limited tunnel space, uneven roads, and long haulage cycles can make equipment matching especially important.

In this project, a 1 CBM LHD loader and a 10-ton-class underground mining dumper truck were selected to work together for ore and waste rock transportation.

1. Project Background

The project required a practical solution for loading blasted material at the underground working face and transporting it to the designated unloading area.

The mine needed equipment that could provide sufficient payload while remaining compact enough for underground roadways.

For this type of application, 8–12 ton underground dump trucks are commonly positioned as a balance between transportation capacity and underground flexibility.

2. Customer Requirements

The customer was mainly concerned with:

Limited underground working space
Efficient loading and transportation
Uneven and inclined mine roads
Reducing waiting time between the loader and truck
Maintaining a stable loading and hauling cycle

The goal was to create a matched loading and hauling system, rather than selecting the two machines independently.

3. Working Conditions

The equipment needed to operate in underground roadways with restricted space, tight turns, uneven surfaces, and slopes.

The main factors considered were:

Tunnel dimensions + haulage distance + road gradient + material type + required payload

For underground dump trucks, these factors directly affect the required vehicle dimensions, payload, ground clearance, and climbing ability. RUIXIN recommends checking tunnel width and height, turning radius, maximum gradient, loading space, and haul distance before selecting a truck.

4. Equipment Selection

1 CBM LHD Loader

The 1 CBM LHD loader handles material collection and loading at the working face.

With a 1 CBM bucket, it provides a practical loading capacity for underground ore and waste-rock handling while maintaining the compact layout required for confined working areas. RUIXIN’s underground loader range includes 0.6 CBM and 1 CBM models.

10-Ton Underground Mining Dumper Truck

The 10-ton underground mining dumper truck serves as the hauling unit.

This payload class provides a balance between carrying capacity and maneuverability, making it suitable for medium-scale underground transportation.

RUIXIN’s underground dump truck range covers capacities from 1 ton to 20 tons, allowing the truck size to be selected according to mine production and roadway conditions.

6. Why This Configuration?

The key reason for combining a 1 CBM LHD loader with a 10-ton-class mining dumper truck is to create a balanced loading and hauling cycle.

The LHD loader collects and loads material at the working face, while the dumper truck transports the material through the underground roadway.

A properly matched combination helps reduce:

Truck waiting time
Loader idle time
Unnecessary hauling cycles
Congestion around the loading area

For example, with a 4.1 m³ cargo box, the truck can carry a substantial volume of material per trip, while the 1 CBM LHD provides repeated loading cycles. The actual number of bucket loads depends on material density, bucket fill factor, and loading conditions.

This means the equipment should be matched based on payload, bucket capacity, haul distance, and cycle time, rather than simply choosing the largest available truck.

7. Delivery

Before shipment, the equipment underwent factory inspection and preparation.

The main systems, including the powertrain, hydraulic system, tipping system, and braking system, were checked before delivery.

After final inspection and transportation preparation, the equipment was shipped to the African mining project.

RUIXIN has also delivered 10-ton underground mining dumper trucks and other underground mining equipment to international customers.

8. On-Site Operation

At the mine site, the LHD loader collects blasted material and loads it into the underground dumper truck.

The truck then transports the material to the unloading point and returns for the next loading cycle:

Loading → Hauling → Unloading → Return

The result is a coordinated underground material handling process in which the loader and truck perform different but complementary roles.

Conclusion

For underground mining projects in Africa, the right equipment combination can make a significant difference to material handling efficiency.

A 1 CBM LHD loader + 10-ton-class underground mining dumper truck provides a practical combination of loading capacity, payload, and underground maneuverability.

RUIXIN provides underground mining dumper trucks and LHD loaders from compact models to higher-capacity equipment. Each combination can be selected according to tunnel dimensions, haulage distance, road gradient, material type, and production requirements.
