ABSTRACT Mine tunneling applications are sensitive to the leakage and friction performance of ducting systems. Improvements in performance can help project economics through reduction in drift height, booster fan spacing, fan electrical power requirement, and deferral of ventilation raise construction. Semi-rigid plastic ducting has enjoyed significant adoption in mine tunneling in recent years. This paper explores technical properties and performance aspects of this relatively new material application.
