1. A dust control system for capturing dust generated during movement of sand through a sand delivery system, comprising:

  • a manifold system including at least one manifold laying on the ground;

    a plurality of flexible conduits in fluid communication with the manifold system, each of the plurality of conduits having a first end coupled to the at least on manifold and a second end for positioning proximate a corresponding one of a plurality of space-apart points along a longitudinal axis of a conveyor forming a portion of the sand delivery system, the second end of each flexible conduit including an inlet for capturing dust in a space proximate the corresponding point during movement of sand along the conveyor system;

    a cover extending substantially along an entire length of the conveyor and enclosing the space proximate each of the plurality of spaced-apart points along the longitudinal axis of the conveyor and the inlet of the corresponding flexible conduit; and

    an air system in fluid communication with the manifold system and the plurality of flexible conduits for drawing air containing dust through the inlets of the flexible conduits.
