Introducing the Premron
Continuous Haulage System
Revolutionary conveying technology for the Underground Mining industry.
Providing the Underground Mining Industry with safe and continuous product haulage.
The Premron CHS forms an enclosed pouch, shaped as a ‘tear drop’ encapsulating the payload ensuring dust free conveying. This system is used to remove product from the face and transport the payload directly to the Panel Belt, hence removing the requirement for Shuttle Cars.
-
The increased process rate can result in a significant advantage when completing a panel using the Premron CHS. The Premron can reduce operational delays in comparison to a shuttle car.
-
Unlike a shuttle car, the miner loads into the Premron CHS and removes coal continuously at up to 500tph. The process rate will be steady throughout the entire pillar being cut as not reliant on wheel distance to the boot end.
-
The Premron provides a significant advantage on cut and production rates in comparison to a shuttle car.
Conveying technology that can increase your Underground Development rates to at least 8m/hr.
The Premron Continuous Haulage System will provide significant operational advantages within underground coal mines.
The Premron CHS utilises the Premron Enclosed Belt System (Premron EBS); a FRAS rubber reinforced belt shaped as a tear drop which encloses the payload and ensures dust free conveying.
The Premron CHS system will introduce new levels of productivity, safety and efficiency in gate road development.
-
The Premron Continuous Haulage System is a monorail mounted closed loop conveyor system that follows the continuous miner during operation, allowing the safe and productive continuous haulage of coal from the face.
The System
Transferring the coal from the continuous miner, directly and continuously to the panel belt conveyor, the Premron CHS removes the requirement for a shuttle car to transfer the coal.The Design
Designed with a modular concept, the Premron CHS facilitates relocation or expansion at any time, and optimises material removal, redistribution and hauling.
The industry advantages for bulk material conveying technology.
Built to strict underground mine compliance, the Premron CHS will withstand extreme conditions whilst delivering a safer and more efficient material handling solution.
Increased productivity for reduced costs
Reduces delays and increases machine utilisation
Development activities can now be done concurrently while you continue mining (NO delay)
Enabler to improve roof bolting performance and hence provide further gains (23m/hr possible - unconstrained)
Safer and environmentally friendly CHS
-
The ability to negotiate tight turns at a small radius (Radius 6m x 90°- typical cut through)
Averaging 7-10m/hr possible within a coal mine gate road with standard support density
Reduce airborne dust - enclosed conveyor system
Reduce manual handling hazards as CHS includes the face services on the machine (power, air, water & return lines)
Ability to have resupply quicker with pods stored under the belt
Ability to ‘Airodust’ concurrently with mining
Ability for concurrent process tasks such as pipe and cable installation
Reduced floor damage due to Premron roof mounted system
Improved OH&S because no moving cars near workers
Productivity Comparison
Data for a simulation demonstrating the difference in performance between a bolter miner loading into a Premron Continuous Haulage System (CHS) and a shuttle car is displayed in this graph, using a pure process without delays, and accounting for the interdependencies of cutting, loading and bolting processes and coal clearance.
As the face is mined further from the boot end of the fixed belt conveyor, the distance the shuttle car has to travel to discharge its load increases.
Consequently the process rate decreases as mining and bolting operations are delayed while waiting for the shuttle car to return for another load.
Virtual Tour of Typical Mine
Tailored to suit unique and varied mine conditions, the Premron CHS system is a highly configurable design customised for customers specific requirements.
Eliminates the wait on shuttle cars
Lightweight structures
Significant advantage on longwall float productivity rates
Ability for Service Vehicles to access along side of conveyor
