Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surface mining methods are used with distribution map data and laser induced breakdown spectroscopy, then measurement accuracy of ore grade is improved, but the invention cannot be applied to underground mining methods
Solution Approach 1:
The patent creates a unified measurement system that functions across both surface and underground mining methods. By establishing a common framework using mobile measurement devices, distribution map data, and standardized processing workflows, the system achieves universal applicability while maintaining measurement accuracy across different mining environments
2Productivity
If more opportunities for measuring ore grade are increased, then productivity is improved, but measurement time and cost increase
Solution Approach 1:
The patent implements continuous measurement capabilities through mobile devices that can continuously collect ore grade data during mining operations. By maintaining continuous measurement action rather than intermittent sampling, the system increases measurement opportunities and productivity without proportionally increasing total measurement time, as the measurements occur during normal mining workflows
Solution Approach 2:
The patent replaces traditional mechanical sampling and laboratory analysis systems with laser-induced breakdown spectroscopy and mobile measurement devices. This substitution enables rapid, in-situ measurements that significantly reduce measurement time while increasing the frequency and opportunities for ore grade assessment, thereby improving productivity

AI summary
A measurement system 50 measures a grade of an excavated material generated from an underground tunnel including a plurality of mining points. The underground tunnel is constructed based on a mining plan of a mine planned based on primary grade data and primary position data corresponding to the primary grade data measured in a preliminary geological survey. The measurement system includes a measuring unit (grade measuring unit) 61 that measures the grade of the excavated material generated from the underground tunnel, a secondary grade data acquisition unit (grade data acquisition unit) 72 that acquires secondary grade data indicating the grade of the excavated material from the measuring unit 61, and a secondary position data acquisition unit (position data acquisition unit) 73 that acquires secondary position data corresponding to the secondary grade data.
