Mine Door Automation

Automate your underground mine door airlocks for increased safety and productivity.
Underground Mine Doors with Automated Controls
At American Mine Door Co., our PLC control packages allow you to secure your airlocks using thru-door scanners sensitive to obstacles between the doors, avoiding injury and damage. Our controls open and close doors via roof mounted sensors, detecting vehicles approaching and exiting the mine door, which also helps eliminate idle time.

  • Increase safety and productivity while maintaining airlock integrity by using an American Mine Door Co. PLC automation package. 
  • 1 door, 2 door “air lock” and 3 door “T” automation control packages available.
  • Each automation package is customized to its application and has been proven in hundreds of installations in many types of mines.
  • We only use the highest quality enclosures and components to assure the reliability and survivability of our automation controls over many years of trouble free service.
