Borehole docking system design for underground refuge chamber and ground maneuver rescue equipment

Résumé

Aiming at the problems of poor efficiency and low efficiency that arise during borehole docking process of ground equipment and refuge chamber in emergency refuge system, a borehole docking system is designed for the ground maneuver rescue equipment in this study. The system mainly includes three parts which are bottom hole docking device, orifice docking device and docking fixation device. Bottom hole docking device is inside the refuge chamber which is designed for three lines: food transmission pipe, air pressure pipe, power and signal transmission line; the orifice docking device is mainly for fast docking of ground equipment and emergency rescue vehicle, and external protection sealing device is designed to protect orifice docking device from harsh environment outdoor; the docking fixation device is the connecting fastening core of the borehole docking device, safeguarding system functions to achieve such as air pressure, power transmission and food supply and so on. Through field test, the system runs well after the docking of emergency rescue vehicle and refuge chamber. Air pressure, water supply and power transmission run smoothly. The operation of monitoring and control, personnel positioning system is normal. The borehole docking system met the needs of the refuge chamber. It enhanced flexibility and economy of mine refuge facility.
