Mine dusts

The instrument has potential to be used as an engineering tool to evaluate the effectiveness of dust control strategies. In a US evaluation performed by Consol Energy the mine operator evaluated the benefit of a proposed new water spray-based dust control system. Engineers measured the dust concentration upstream and downstream of a production location under different dust control scenarios using two of the personal dust monitor units. By evaluating the change in the dust loading between the upstream and downstream monitoring sites, the company was able to determine in a few hours which hardware configuration would yield the greatest benefit to the workplace environment.
