Prefabricated Inclined Conveyor Track for Mining Trucks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inclined conveyor systems for mining trucks in surface mining are costly to construct and maintain due to the use of in-situ concrete, making it difficult to expand or modify the infrastructure as mining progresses.
Innovation Solution
A prefabricated inclined conveyor system using finished parts with a foundation created from overburden, featuring a conveyor platform and counterweight running on separate tracks, anchored to the subsoil for stability, and designed for easy assembly and expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If in-situ concrete is used to construct inclined conveyor systems, then the structural strength and stability are improved, but the construction cost increases and flexibility for expansion decreases
Solution Approach 1:
The inclined conveyor system is divided into modular track sections that can be assembled from pre-fabricated components. Each track section consists of standardized elements that can be easily connected and disconnected, allowing for cost-effective construction and flexible expansion as mining operations progress.
Solution Approach 2:
The system uses adjustable track components that can be configured for different slopes and configurations. This allows the same standardized components to adapt to varying mining conditions without requiring custom concrete construction for each scenario, reducing costs while maintaining structural integrity.
2Stability of the object's composition
If in-situ concrete is used for inclined lanes, then the structural stability is improved, but the ability to expand or change the lane as mining progresses deteriorates
Solution Approach 1:
The conveyor track is constructed from discrete, interchangeable modular sections that can be assembled in different configurations. This segmentation allows the system to maintain stability through standardized connections while enabling easy expansion or reconfiguration as mining funnels widen and operations progress.
Solution Approach 2:
The track system incorporates adjustable and reconfigurable components that allow the conveyor lane to dynamically adapt to changing mining conditions. Track sections can be added, removed, or repositioned to follow the evolving geometry of the mining funnel without requiring permanent concrete construction.
3Ease of manufacture
If prefabricated parts are used for the track, then the construction cost and installation time are reduced, but the complexity of assembly increases
Solution Approach 1:
Standardized universal connection mechanisms are used across all track sections, allowing the same assembly procedures and components to be reused throughout the entire conveyor system. This universality simplifies the assembly process despite the modular nature of the construction, reducing both cost and complexity.

AI summary
The invention relates to a method for producing a finished-part track for an inclined conveyor system having a conveying platform and a counterweight in opencast mining, comprising the following steps: providing a foundation; placing at least one base element, which comprises base members and cross members, onto the foundation; fastening the base element to the foundation; placing track elements onto the base element, while adjustable spacer elements, at least one respective shear cleat, and a support are arranged between the base element and track element; and orienting the track elements relative to one another, with respect to the respective base elements, by means of the spacer elements.
