Résumé :
|
A pilot-plant experimental investigation is described into the pneumatic conveying of large ice particles through long pipelines extending down deep mine shafts. Various regimes of two-phase flow were observed in the various vertical and horizontal sections of the pipeline, including dilute-phase flow and cohesive plug flow. Equations are presented for the prediction of pressure gradients along the respective sections, with empirical correlations for solids friction factors. The investigation proved the feasibility of conveying ice underground for mine-cooling purposes.
