Dynamic Mine Safety Zone for Unmanned Vehicle Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mines, unexpected interference can occur between unmanned vehicles and manned vehicles or workers, posing safety risks while also potentially reducing productivity if safety functions are excessively activated.
Innovation Solution
A mine management system that includes an entrance determination unit, abnormality monitoring unit, entrance prohibited area setting unit, and alarm device control unit to ensure safety without excessively reducing productivity by determining if a manned vehicle enters an unmanned vehicle's operation area, monitoring its communication and position states, setting an entrance prohibited area, and activating an alarm if the vehicle is not manipulated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety functions are activated to ensure safety of manned vehicles and workers, then safety is improved, but productivity is reduced
Solution Approach 1:
The prohibited area is dynamically adjusted based on the operational state of the manned vehicle. When the vehicle is operating normally, the prohibited area is limited to the immediate vicinity. When an abnormality is detected (communication loss or position detection failure), the prohibited area is automatically expanded to a larger radius, and unmanned vehicles are restricted from entering this expanded area. This dynamic adjustment ensures safety when needed while minimizing impact on productivity during normal operations.
2Reliability
If the entrance prohibited area is expanded to ensure safety, then safety is improved, but the operation area for unmanned vehicles is reduced
Solution Approach 1:
The prohibited area radius is dynamically changed based on the detection of abnormalities in manned vehicles. Under normal conditions, the prohibited area maintains a smaller radius allowing broader operation for unmanned vehicles. When communication state or position detection state becomes abnormal, the system automatically expands the prohibited area radius to ensure safety, temporarily restricting unmanned vehicle access to the expanded zone until the abnormality is resolved.
3Reliability
If monitoring of communication state and position detection state is performed, then safety is improved, but device complexity is increased
Solution Approach 1:
The system continuously monitors the communication state and position detection state of manned vehicles, creating a feedback loop. When abnormalities are detected (loss of communication or position data), the system automatically responds by expanding the prohibited area and notifying relevant parties. This feedback mechanism enables automated safety management without requiring complex manual intervention systems.

AI summary
Provided is a mine management system for a mine where an unmanned vehicle operates in an operation area of the mine, including determining based on position data of a moving body which is different from the unmanned vehicle whether the moving body enters the operation area, starting monitoring abnormality including abnormality of at least one of communication state and position detection state of the moving body based on manipulation on an input device installed in the moving body, setting an entrance prohibited area where entrance of the unmanned vehicle is prohibited to include a position of the moving body and activating a function of expanding the entrance prohibited area when an abnormality is detected, and activating an alarm device installed in the moving body when it is determined that the moving body enters the operation area and the input device is not manipulated.
