Mine Waterproofing
Mining operations require the use of large quantities of water for numerous operations. Over time, the equipment and operations to a mine may be exposed to adverse conditions caused by the presence of water, improper drainage, and other issues. As such, it is important to ensure the adequate treatment of water used in the mine and the proper waterproofing of buildings and structures.
Waterproofing of a mine can be divided into several categories: improved drainage and ground water control, construction materials and sealants, and various waterproofing systems. Improved drainage and ground water control is an important and often overlooked factor in mine waterproofing. If a mine is located in areas with a high water table, the ground water must be managed to prevent flooding, seepage, and potentially result in bond failure and material defections.
Drains, subsurface drainage sheets, and other waterproofing devices should be installed to reduce water gathering and the potential for water leakage and seepage. Generally, the placement of these devices should be strategically placed to eliminate hydrostatic pressure and allow for free draining.
The second factor in mine waterproofing is the selection of appropriate construction materials and sealants. A combination of water-resistant sealants and materials, such as PVC and polyurethane, should be used to provide an effective barrier between the mine and external water. These materials may also reduce the chance of corrosion of metals and associated surfaces.
Finally, various waterproofing techniques may be used, such as membranes, coatings, and sealants, to provide a waterproof barrier, seal the surface of the building, and protect against water infiltration. Some coatings are designed for interior and exterior use, to provide additional protection against water and moisture damage.
Mine waterproofing is an important aspect of ensuring the safety and durability of mine equipment, buildings, and structures. Proper drainage and ground water control, construction materials and sealants, and various waterproofing techniques all play a significant role in preventing water damage and seepage. When addressing the risks associated with water in a mine, it is important to consider these and other techniques to ensure waterproof protection.
