    An Introduction To Surface Mining

    Openpit mining is usually utilized for nearsurface deposits, such as gravel and sand. The term "quarry" often refers to an openpit mine, where the product is rock (commonly building stone) usually either gravel, sand, or dimension stone. Openpit mining is relatively safe and cheap, and it also yields more final products.
