CINF Engineering Corporation Limited

This invention is applicable for the airleakage drainage system for the mine underground ventilator chamber. The hydrostatic pressure with given height of water column is designed inside the drainage pipe to stand up to the air pressure difference at the both ends of the drainage pipe occurred during the ventilation operation so as to prevent the air leakage from the drainage pipe. It is characterized by simple structure and reliable sealing property.
