Reversible method of ventilation 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 discharge method of ventilation does not provide rapid removal of harmful gases after blasting. Suction method of ventilation is also ineffective, as in the bottom-hole space is formed, a large volume of slow-moving air ...
