  11. 11. Considerations of use •  Water quality •  Conservation of water •  Ease of use and effectiveness to wet surface areas of substrate material. Advantages: •  Good short term dust suppression, assuming the dust particles are contacted and wetted - agglomerates the surface particles. •  Often available on site and can be inexpensive Mine Site Dust Control Methods of Dust Prevention Water
  12. 12. Mine Site Dust Control Methods of Dust Prevention Water Disadvantages. •  Unsustainable practice - no water is recycled •  Dust control short term: (2 treatments per day often) •  Can be ineffecient dust supressant •  High operating costs: water carts, water, operators •  Operational delays due to ineffective dust control •  Loss of water - environmental impact •  No DEM moisture control.
  13. 13. Roads and Trafficable Areas •  Optimising water usage in dust suppression on haul roads, and exploring cost effective alternative options. •  Roads and trafficable areas •  Application tips and considerations. •  Access roads. •  Haul roads. •  “Shandy Mixing” •  Water cart / dust control teams and control.
