Environmentally Sound Practices in the Aggregates Industry: Chapter 02

This is clip 2 of 7 for this video. Air and noise pollution are two major concerns that communities have about neighboring mining operations. Governmental regulations are in place to limit the amount of air emissions allowed in the mining industry. Two types of air emissions must be controlled, point-source and fugitive emissions. Wet-suppression, Bag-house filtration, or enclosures can reduce point-source dust emissions. Wetting aggregate pile during loading, wetting roadways and controlling the speed limit of vehicles will reduce fugitive emissions. Blasting creates short term dust emissions and ground vibrations. Acceptable blasting times and vibration limits must be adhered to in order to minimize community complains. Enclosures will also reduce the amount of noise pollution emitting from the plant. Shrubs and trees will act as a buffer zone between operational noise and the community.

Very good video, informational.

Did anyone notice the fellow at 3:13 wearing his safety helmet backwards? Its great, the highlighted topics, but the video fails to shoot individuals working under safe practice. I think the funniest part is that the video mentions "only licensed contractors or qualified company personelle should be using explosives...proper engineering for shot preparation... (with engineer wearing hard hat backwards)" 2:57
