发明名称 Apparatus, system, and method for supporting a gate entry for underground full extraction mining
摘要 An apparatus, system, and method are disclosed for supporting a gate entry or a connecting entry. The apparatus includes a support member, a controller, and a vehicle. The support member is configured to selectively engage a mine roof and a mine floor within a gate entry. The controller communicates with the support member to extend the support member to engage the mine roof and mine floor and retract the support member to disengage the mine roof and mine floor. The vehicle is connected to the support member and controller and moves the support member in response to a motive force. The support member, controller, and vehicle can operate and move independent of a mining face conveyor. The present invention is reusable, provides for mine roof and mine floor support as well as support of gate entry walls. The present invention has a minimal width profile to provide support while minimizing interference with the airflow within the gate entry. In addition, the present invention forms an access passage for personnel, equipment, and airflow that remains safely open during full extraction mining operations even as load abutments shift due to full extraction mining.
