Measuring Truck Productivity in Underground Mines

In most underground mining operations, truck and LHD operators are unable to consistently load haulage trucks to nominal load capacity. The variables preventing consistent loading include the variation in the density of materials, rock size, and the differences between development and high-grade ore. Inconsistent loading means trucks only haul a fraction of what they have been designed for. Without real-time visibility, operators cannot take action to maximize the amount of material loaded into truck beds and they lack transparency in their hauling process

Globally, underground mines lose up to 30% of hauling efficiency due to lack of visibility.

In most underground mining operations, truck and LHD operators are unable to consistently load haulage trucks to nominal load capacity. The variables preventing consistent loading include the variation in the density of materials, rock size, and the differences between development and high-grade ore. Inconsistent loading means trucks only haul a fraction of what they have been designed for. 

Without real-time visibility, operators cannot take action to maximize the amount of material loaded into truck beds and they lack transparency in their hauling process. 

Increase Visibility, Transparency, Productivity.

Newtrax Truck Productivity Solution maximizes loading cycles by providing real-time visibility of the payload weight, enables transparency through reporting of accurate data. The result is increased productivity and an optimized haulage process.

Maximize Load Capacity

The solution uses a compact vibrating wire sensing technology which can easily be fitted to ANY truck found in an UG operation, enabling the operators of trucks and LHDs to maximize their loading cycle—through the use of the internal and external payload displays—and ensuring trucks are always loaded to capacity. 

Enable Transparency Through Reporting

Through the collection, monitoring, and analysis of data, operations management can achieve the transparency they need for the hauling process, have the ability to establish and enforce their hauling strategy (10-10-20), as well as ensure operators can meet their productivity targets and bonuses. 

Additionally, truck box size can be optimized to the tunnel, including the addition of an extention on top or adding a tailgate, without risking the opposite effect of overloading the haulage truck. 

Prevent Excessive Equipment Downtime

Newtrax Truck Productivity Solution is standardized for all trucks and does not require periodic calibration, reducing the need for specialized maintenance personnel to maintain the system or the need for long lead time custom components. Through consistent collection of data, premature wear and excessive equipment downtime can also be prevented.

Advantages 

• Sensors are simple to install and maintain and require no modifications to the vehicle frame or hydraulic system 

• Designed with a unique vibrating wire sensor technology to also fit ejector trucks 

• Does not require periodic calibration, unlike other solutions 

Features 

Real-time payload is automatically broadcasted to the payload display and stored on the Newtrax Data Logger without operator intervention 

Comprehensive reporting and real-time dashboard capability to track material movement and productivity (actual vs planned), along with all relevant KPIs such as cycle time, and hauling intensity [Tn x Km/h] 

Payload is monitored at every moment, providing visibility on wet material packing in the dumper bed (carry back) and notifies the operator to schedule a box cleaning 

NET payload hauled is returned, comparing the weight before and after dumping
