Haul Road Dust Suppression Case Studies

88Chemco performed dust suppression case studies to demonstrate how Hydrogel Water Extender was used for mitigating dust. The purpose was to measure the time of dust control effectiveness when adding Hydrogel to the Water Cart relative to using water only.

Savings from Hydrogel Road Dust Suppression

• Dust Levels and Safe Operating Conditions
• Water Cart Cycles
• Diesel in Water Carts
• Water used for Dust Suppression
• Reduced water per m2 by changing Water Cart Spray Valve to Magnum Australia Valve

Case Study – Dust Suppression on Coal Mine

Dust Suppression using Hydrogel Water Extender

was utilised at a coal mine on a busy haul road of approximately 29 vehicles/hour.

The temperature was approximately 31 Deg C.

KPI	Current	Achieved
Water used per m2 per shift	3.68L/m2/shift	0.61L/m2/shift (83% water saving)
Expected Water Cart Cycles/12 hours	8 Cycles	3 Cycles

Before and After Hydrogel Water Extender

Case Study – Dust Suppression on Hard Rock Mine

Dust Suppression using Hydrogel Water Extender

was utilised at a hard rock mine on a busy haul road of approximately 50 Ultra-Class vehicles/hour.

The temperature was approximately 34 Deg C.

KPI	Current	Achieved
Water used per m2 per shift	3.84L/m2/shift	1.92L/m2/shift (50% water saving)
Expected Water Cart Cycles/12 hours	8 Cycles	4 Cycles
