摘要：
A study was conducted to determine the feasibility and effectiveness of a secondary ventilation system retrofitted onto an Eickhoff EDW 340L double-drum shearer as a technique for controlling respirable dust generated during a longwall mining operation. Field results indicated that the secondary ventilation system reduced respirable dust more than 60% along the face. Reduction was less near the intake airway and when secondary dust sources occurred.
