Abstract

A personnel access door assembly of an opposing wing of a mine ventilation door. The personnel access door includes a frame including a top portion, a bottom portion, a first post portion and a second post portion, the top frame portion and the bottom frame portion coupled to respective top and bottom ends of the first post and second post portions. The personnel access door further includes sets of trolley wheels affixed to the top or bottom of the frame to engage a top rail or bottom rail affixed on the opposing wing.

Abstract

A mine door control system and method that uses sensor input from a plurality of sensors corresponding to at least one of a position of at least one associated opposing wing mine door and a path through the at least one associated mine door to determine at least one predefined action in accordance with received sensor input. A control command is then communicated a drive mechanism associated with the at least one associated mine door, the control command including instructions for operating the drive mechanism in accordance with the at least one predefined action.

Abstract

A high-pressure mine door assembly for use in mine shafts, the door assembly configured with opposing wings, which enable the door assembly to open and close quickly. The assembly includes a major hub and a minor hub positioned at or above the cap of the door assembly and coupled together via a connecting bar. A drive mechanism is coupled to the cap and the connecting bar, which facilitates the opening and closing of the wings of the door assembly. The door assembly is configured in a 12-6 pitch orientation, requiring only a ⅔ rotation of the wings to fully open the door assembly to. Such a configuration also negates the effect of air pressure on operation of the door assembly, regardless of the direction of the airflow, with the airflow assisting one wing in opening and the other in closing.
