Mine Route Validation and Requirement Control for Work Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mine site administrators lack a suitable method to identify and select valid route segments for work machines and apply operational requirements, especially in changing physical conditions, which can lead to unsafe or inefficient operations.
Innovation Solution
A system and method using a graphical user interface to select candidate routes, validate them based on prior knowledge of valid nodes and interconnections, and apply route requirements dynamically, ensuring only valid routes are set for work machines, allowing real-time modification and display of route requirements as overlays on a map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If administrators manually identify and select route segments for work machines, then operational control can be established, but the process becomes time-consuming and prone to errors in changing physical conditions
Solution Approach 1:
The system performs preliminary validation of candidate routes against stored mine map data, valid nodes, and interconnections before administrators confirm route selection. This preliminary action automatically identifies valid route segments and flags invalid portions, significantly reducing the time administrators would otherwise spend manually verifying route validity in changing physical conditions.
2Measurement precision
If the system validates candidate routes based on prior knowledge of valid nodes and interconnections, then route accuracy improves, but the complexity of the system increases
Solution Approach 1:
The system pre-stores valid nodes and interconnections from mine surveys in a database before route selection is needed. When administrators select candidate routes, the system automatically validates them against this pre-prepared data, achieving high validation accuracy without requiring complex real-time analysis. This preliminary preparation of reference data simplifies the actual route validation process.
Solution Approach 2:
The system introduces an intermediary validation layer that automatically compares candidate routes against stored mine map data, valid nodes, and interconnections. This intermediary process acts as a mediator between administrator input and final route confirmation, ensuring accuracy while keeping the user interface simple and manageable.
3Adaptability or versatility
If the system allows real-time modification of route requirements, then adaptability to changing conditions improves, but the risk of setting invalid requirements increases
Solution Approach 1:
The system provides immediate feedback when administrators modify route requirements by validating changes against stored mine map data and operational constraints. The feedback mechanism alerts administrators to potentially invalid modifications and prevents confirmation of erroneous changes, allowing flexible adaptation to changing conditions while maintaining reliability through continuous validation.
Solution Approach 2:
Before finalizing modified route requirements, the system performs preliminary validation checks against the stored mine map and operational constraints. This preliminary validation of modifications ensures that adaptability to changing conditions does not compromise the reliability and validity of route requirements.

AI summary
A system, method, and apparatus can access, via a user interface, route properties of a mine site used for controlling one or more work machines as the work machine(s) travel through the mine site. Access regarding the route properties can include viewing one or more of the properties and/or setting requirements (e.g., restrictions or limitations) for one or more of the properties. A candidate route can be selected, validated, and set as a selected route using the user interface to access route properties associated with the selected route. Requirements can be set for one or more of the route properties using the user interface. The work machines can be controlled to traverse the mine site according to the requirements set for the route properties.
