Reversible method of ventilating on of long dead-end mine workings of large cross-section after blasting operations
Abstract
Ventilation of hydraulic and transportation tunnels is complicated by a large cross-section of underground excavations, their considerable length and a large volume of blasting operations. Due to low air velocities in such excavations, the most common forcing method of ventilation does not provide rapid removal of harmful gases after blasting. Exhaust ventilation is also ineffective, as a large volume of slow-moving air is formed in the face area. ...
