Physical Characteristics at a Surface Mine Explained

If you’re new at a surface mine, you’ll notice there’s a lot of specialized language: berm, highwall, pit, and more. If all that lingo has got you longing for understanding, this article is for you. We’re going to explain the terms typically used to describe the physical characteristics in a surface mine.

Sediment control practices Stabilized earth/soil berm

Jun 13, 2019 Berms are compacted or vegetated structures designed to slow, pond, or filter runoff; divert runoff on a construction site to a sediment trap/basin; and/or ensure clean upland runoff does not move into disturbed areas.They may also be called filter berms, diversion berms, or earth berm barriers, depending on their composition and use.

General Physical Characteristics of Surface Mines MSHA

Surface mines typically include the pit, benches, highwalls, stockpiles, wastepiles, settling tanks or ponds, berms, and haul roads. What is the pit? The dominant feature in an open pit or quarry operation is the pit, a broad, deepened, often funnel-shaped area where overburden has been removed to access the material to be mined.
