In modern coal mining, advancements in sensor and computer technology have enabled the remote operation and automatic control of several key systems to improve safety and efficiency.1
Remotely Operated and Automatically Controlled Systems
- Longwall Mining Equipment: In mechanized longwall operations, longwall shearers and longwall shields can be remotely operated.1
- Continuous Miners: These machines are frequently equipped with automatic controls to manage their operation.1
- Highwall Mining: This method utilizes a continuous miner that is remotely operated from a cabin located at the surface. Operators use television cameras to monitor and control the machine's progress as it advances into the coal seam.2
- Environmental Monitoring: The underground atmospheric environment is remotely monitored for air velocity, airborne dust, and the concentrations of various gases.1
- Auxiliary Systems: Fans and pumps are monitored continuously to track their operational status and characteristics.1
These technologies allow for greater control over mining conditions and equipment performance, significantly reducing the need for direct human presence in hazardous areas.12
