Screening operation- MSHA

Comments Off on Screening operation- MSHA
Another MSHA site where they are actually not crushing rock or selling it. This location only screens the rock/dirt and loads it. It’s transported to another location where they screen it again (wet, this time) and sell it. They had two loaders and an excavator working this pit. We would have normally performed air and noise monitoring at the at the crusher location. However, the crusher was actually not crushing rock and was only screening the rock wet. At this location they were at least screening dry. We figured this would be the best chance of finding any dust. However, we found hardly anything.
There was nothing too exciting or unique, other than a strong wind in the afternoon and a pesky pheasant that remained out of site, but kept cackling.
