Cement Bentonite Soldier Pile Walls, also known as CBSP, are a cost-effective means for watertight support of excavation that has little to vibration to adjacent structures. CBSP is typically used for temporary open-cut structures.
Fig 1 above is an image of an open pit recently left by a mining company. Pits can cause several health problems such as malaria (open pits contains stagnant water), and unsafe structures that can cause unstable conditions in that area resulting in several accidents.
Major clays production comes from Tertiary and Cretaceous basins in western, southern, and Central Bohemia, while the bentonite production is concentrated in the areas of Tertiary volcanism in the western and northwestern parts of the Czech Republic. All clays and bentonite deposits are extracted by open pits (quarries).
Open pits are developed in the mining industry for the extraction of minerals, raw materials, and aggregate. In many circumstances, these pits are excavated below the water table. Depending on the geologic environment and proximity of streams, rivers, ponds and lakes, significant groundwater inflows may occur. The magnitude of these inflows must …

The northern Black Hills bentonite mining district includes parts of Crook County, Wyo., Carter County, Mont., and Butte County, S. Dak. Within this district, many beds of bentonite occur interspersed with sedimentary strata of Cretaceous age that have an average total thickness of about 3,000 feet and consist chiefly of marine shale, marl, and …
Open-pit mines, also known as surface mines, are vast engineered excavations on the Earth's surface. They are a common sight in mining for resources such as copper, gold, iron, and coal. While these mines are instrumental in supplying the raw materials for our modern lifestyle, they come with substantial human health hazards that …
