Mine Control System for Real-Time Excavation Progress Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring and controlling mine operations in large mines is challenging due to the difficulty in obtaining an overall view of the excavation progress and ensuring that operations adhere to the designed plan, as existing systems provide scattered information and require extensive infrastructure and skilled workers.
Innovation Solution
A mine control system where mine vehicles equipped with on-board monitoring means communicate with external control units to provide data for comparison with mine plans, allowing for real-time monitoring and updating of 3D models of the mine, enabling effective resource utilization and early detection of deviations without the need for extensive infrastructure or skilled labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional scattering information collection methods are used in mines, then infrastructure requirements are reduced, but the ability to obtain an overall view of mine operations deteriorates
Solution Approach 1:
The patent combines multiple monitoring functions (position tracking, excavation progress monitoring, resource utilization tracking) into a single integrated control unit that receives data from various mine vehicles. This merging of previously scattered information sources into one centralized system provides an overall view of mine operations while managing system complexity through integration.
Solution Approach 2:
The control unit is designed with multi-functionality, serving as a central hub that performs multiple tasks: collecting position data, comparing excavation progress against plans, monitoring resource utilization, and generating comprehensive reports. This universal approach allows one system to address multiple monitoring needs simultaneously, improving information completeness without proportionally increasing complexity.
2Measurement precision
If extensive surveying and measuring infrastructure is deployed in mines, then measurement precision improves, but device complexity and cost increase
Solution Approach 1:
The system enables mine vehicles to monitor their own excavation progress and position autonomously. Each vehicle's control unit self-measures its own operational parameters (position, excavation volume, progress) and transmits this data to the central control unit. This self-service approach achieves precise measurement without requiring external surveying infrastructure or skilled measurement workers.
Solution Approach 2:
The patent replaces traditional mechanical surveying infrastructure (theodolites, total stations, manual measurement equipment) with electronic sensing and data communication systems integrated into mine vehicles. This substitution uses electronic sensors and digital communication to achieve measurement precision while eliminating the need for extensive physical surveying infrastructure.
3Productivity
If manual monitoring methods are used in mines, then ease of operation is maintained, but productivity and response time deteriorate
Solution Approach 1:
The control unit continuously receives real-time data from mine vehicles and automatically compares excavation progress against the mine plan. This automated feedback mechanism provides immediate information on deviations from the plan, enabling rapid response and corrective actions. The system processes and analyzes data automatically, significantly improving monitoring efficiency and productivity compared to manual methods.
Solution Approach 2:
The system performs preliminary automated analysis of monitoring data, comparing actual excavation progress against planned parameters before human operators need to review the information. This preliminary action filters and processes data in advance, presenting only relevant deviations and insights to operators, thereby maintaining ease of operation while dramatically improving productivity and response time.

AI summary
The invention relates to a mine control system for monitoring mine operations. The system comprises several mine vehicles provided with on-board monitoring means. Monitoring data is transmitted from the mine vehicle to a mine control system, which is provided with a mine plan. The mine control unit is configured to compare the received monitoring data with the mine plan and is determines the current state of the mine relative to the mine plan on the basis of the monitoring data.
