Boundary Tracking System for Mining Ore Dilution Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blasting in mining operations leads to non-uniform rock-mass movement, causing inaccurate delineation between high-grade ore, low-grade ore, and waste regions, resulting in ore loss and dilution, and existing monitoring methods are labor-intensive and prone to human error.
Innovation Solution
A boundary tracking system comprising signal transmitting devices, a receiving device, and a controller that determines the location of these devices to automatically track and display boundary movements, enabling precise control of work machines during excavation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual detection of BMMs is used to track boundary movements, then ore loss and dilution can be reduced, but labor intensity increases and detection efficiency decreases
Solution Approach 1:
The patent replaces the manual mechanical detection method with an automated electronic detection system. The handheld detector that operators carry is replaced by a receiver mounted on the work machine that automatically detects BMM signals, eliminating manual labor while maintaining boundary tracking accuracy.
Solution Approach 2:
The work machine performs its own boundary detection function through the integrated receiver system. Instead of requiring separate manual detection operations, the machine autonomously detects BMM positions and provides real-time boundary information to the operator through the display system.
2Measurement precision
If manual plotting of BMM positions is performed, then boundary tracking is achieved, but time consumption increases and human error occurs
Solution Approach 1:
The manual plotting process is replaced by an automated computer system that receives BMM position data from the detector and automatically plots boundary positions on the display. This eliminates manual plotting time and reduces human error while maintaining measurement precision.
Solution Approach 2:
The controller acts as an intermediary between the detector and the display system. It automatically processes detector signals, calculates BMM positions, and generates visual representations on the display, eliminating the need for manual data transfer and plotting operations.
3Loss of information
If operators interpret plots manually during excavation, then boundary information is available, but human error increases and operational efficiency decreases
Solution Approach 1:
The controller serves as an intermediary that automatically processes boundary data and presents it in an easily interpretable visual format on the display. This eliminates the need for operators to manually interpret complex plots, reducing human error and improving operational ease.
Solution Approach 2:
The display system uses visual representations including color-coded indicators to show boundary positions and work machine location. This provides intuitive visual information that is immediately recognizable to operators, eliminating the need for manual interpretation of monochromatic or complex plots.
4Reliability
If no real-time boundary tracking is provided, then system complexity is reduced, but ore loss and dilution increase
Solution Approach 1:
The receiver system serves multiple functions: detecting BMM signals, determining boundary positions, tracking work machine location, and providing real-time visual feedback. This multi-functionality achieves reliable ore recovery accuracy without proportionally increasing system complexity.
Solution Approach 2:
The system provides real-time feedback to the operator through the display, showing current work machine position relative to boundary locations. This continuous feedback loop enables immediate corrective action to prevent ore loss or dilution without requiring complex post-processing or analysis systems.
