Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In open pit mining, the efficient deposition of overburden material on terrains with multiple planes or sloped surfaces is challenging due to the need for extensive movement of conveyor systems and multiple conveying elements, which increases operational complexity and costs.
Innovation Solution
A method utilizing a belt conveyor system with a traveling tripper and a movable connecting belt bridge to transfer material to a stacker, allowing for minimal conveyor system movement and efficient filling of multiple planes with extended filling strips, using a stacker with articulated pick-up and discharge belts for lateral and height adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a belt conveyor system is used to deposit material on terrains with multiple planes or sloped surfaces, then material deposition is achieved, but extensive movement of the conveyor system is required which increases operational complexity
Solution Approach 1:
The patent applies dynamics by making the conveyor system movable rather than fixed. The belt conveyor system can be repositioned along the terrain to deposit material on multiple planes without requiring extensive disassembly or complex operational procedures. The movable design allows the conveyor to adapt to different deposition locations while maintaining operational simplicity.
Solution Approach 2:
The terrain is segmented into multiple planes or levels, and the conveyor system deposits material on each plane sequentially. This segmentation allows the conveyor to work on one plane at a time, reducing the complexity of simultaneous multi-plane operations and enabling systematic material deposition across varying elevations.
2Adaptability or versatility
If multiple conveying elements are used to handle material on sloped surfaces, then material deposition capability is improved, but the number of conveying elements increases which increases costs
Solution Approach 1:
The belt conveyor system is designed with multi-functionality to handle material deposition on various terrain configurations. A single conveyor system can deposit material on multiple planes, perform both horizontal and vertical material transfer, and adapt to different deposition patterns. This universality eliminates the need for multiple specialized conveying elements, reducing overall system complexity and cost.

AI summary
A method for filling a terrain using bulk material, preferably excavating material from an ore mine. The method includes a) the terrain has at least three levels disposed parallel to each other; b) a conveyor system (1) by which the bulk material is conveyed is positioned on at least the level second from the bottom; c) a traveling tripper (2) can be displaced along the entire conveyor system (1), by which the bulk material on one or the other side of the conveyor system (1) can be transferred to a connecting conveyor bridge (3) that can also be displaced along the conveyor system (1); d) the connecting conveyor bridge (3) transfers the bulk material to a depositor (4) that can also be displaced along the conveyor system (1); e) the depositor (4) successively deposits the bulk material in elongated filling strips (A-G) on the various levels below and above the level (0) of the conveyor system (1); f) initially one or several levels below or above the level (0) are each filled with at least one strip (A-D or E-G) on one side of the conveyor system (1); and g) the traveling tripper (2), connecting conveyor bridge (3), and the depositor (4) are subsequently displaced to the other side of the conveyor system (1) in order to fill the corresponding filling strip at that location as well.
