Solution Overview
Problem
Existing mining automation systems face challenges in accurately and efficiently attaching mining machines to operation zones without user intervention, particularly due to unreliable positioning technologies, which can lead to incorrect attachments and compromised safety.
Innovation Solution
A system that utilizes a combination of positioning devices and reliability ratings to automatically attach mining machines to operation zones based on the accuracy of detected positions, allowing attachment without user confirmation when reliability criteria are met, and controlling operations accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic attachment of mining machines to operation zones is implemented without reliability assessment, then productivity and ease of operation are improved, but reliability and safety deteriorate due to incorrect attachments
Solution Approach 1:
The system performs preliminary reliability assessment of positioning data before executing the attachment operation. The control device evaluates positioning reliability indicators in advance, and only proceeds with automatic attachment when the reliability meets predetermined thresholds, thus preventing incorrect attachments while maintaining automation
Solution Approach 2:
The system continuously monitors positioning reliability indicators and provides feedback to the control device. Based on this feedback, the control device dynamically adjusts whether to proceed with automatic attachment or request manual confirmation, creating a closed-loop control system that balances automation with safety
2Reliability
If user confirmation is required for all attachment operations, then reliability is improved, but productivity and ease of operation deteriorate due to increased manual intervention
Solution Approach 1:
The system applies user confirmation requirements selectively rather than universally. When positioning reliability is high, automatic attachment proceeds without user confirmation (partial action). When reliability is uncertain, user confirmation is requested (excessive action). This partial application of confirmation requirements optimizes both safety and efficiency
3Measurement precision
If positioning technology with higher accuracy is used, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The system changes the parameter being measured from raw position coordinates to positioning reliability indicators. By evaluating the reliability of positioning data rather than relying solely on high-precision positioning hardware, the system achieves accurate attachment decisions using existing positioning technologies, thus avoiding the need for more complex and expensive positioning systems
4Ease of operation
If automatic attachment is implemented without reliability assessment, then ease of operation is improved, but the risk of harmful factors increases due to incorrect zone assignments
Solution Approach 1:
The system performs preliminary reliability assessment before executing automatic attachment, evaluating positioning data quality in advance. This preliminary action prevents harmful outcomes by identifying unreliable positioning scenarios before they can cause incorrect attachments, while maintaining operational simplicity for reliable cases

AI summary
Example embodiments relate to controlling of a mining machine. An apparatus may comprise: at least one processor; and at least one memory including program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: receive an indication of a position of the mining machine; determine that the position of the mining machine is within an operation zone; determine a reliability rating for the position of the mining machine; attach the mining machine to the operation zone without requesting, via a user interface, a confirmation of the attachment of the mining machine to the operation zone, in response to determining that the reliability rating meets a condition; and control operation of the mining machine based on the mining machine being attached to the operation zone.
