A high-pressure mine door assembly, comprising:
- a frame including a cap frame portion, a sill frame portion, a first post frame portion and a second post frame portion, the cap frame portion and the sill frame portion coupled to respective top and bottom ends of the first post frame and second post frame portions;
- a major wing pivotally coupled to the cap frame portion via a major cap bearing and the sill frame portion via a major sill bearing, the major wing including a major hub located adjacent to the major cap bearing;
- a minor wing pivotally coupled to the cap frame portion via a minor cap bearing and the sill frame portion via a minor sill bearing, the minor wing including a minor hub located adjacent to the minor cap bearing;
- a connecting bar having a first end moveably coupled to the major hub and a second end moveably coupled to the minor hub;
- a single drive assembly operatively coupled to the connecting bar and configured to rotate the major and minor wings of the mine door assembly in opposing directions;
- at least one sensor operative to sense operations of the high-pressure mine door;
- and
- a control system in communication with the at least one sensor, the control system comprising:
- a processor;
- a sensor analysis component in communication with the processor, the sensor analysis component configured to receive sensor data from the at least one sensor;
- memory in communication with the processor, the memory storing instructions which are executed by the processor for:
- receiving sensor input from the at least one sensor corresponding to at least one of a position of the major wing or minor wing and a path through the high-pressure mine door;
- determining a predefined action in accordance with received sensor input;
- and
- operating the single drive assembly associated with the high-pressure mine door in accordance with the determined predefined action responsive to the received sensor input.
