How to Control Dust mapyourshow

2/29/2016 4 Reasonably Available Control Measures • Operational Controls: Train operators to minimize dust. Speed control is a good a example. • Engineered Controls: Enclosing and containing dust sources can often be done with in-house labor and material. • Wet Suppression Systems: Water is the most common dust suppressant to control dust from roads, piles and processing.

Near field modelling of dust emissions caused by drilling

Dust is an environmental issue at many quarries and crushing is the most significant source of it [1, 2].According to Sairanen and Selonen [] drilling is the most dust producing activity in natural stone quarries.Aggregate production is reported to generate mainly coarse (PM 10 or larger) particles [4, 5], whereas the majority of the dust generated during the drilling is PM 10 [].
