Technology of mining watered rock mass by draglines
Abstract
At many operating quarries non-metallic minerals are extracted only up to the level of groundwater, and large reserves of raw materials lying below the water-bearing horizon are considered off-balance sheet and are not developed. The depth of deposit development can be increased at the expense of watered reserves by using draglines, which provide excavation of blasted rock mass from under water from a great depth.
