Environmental impact of mining - Wikipedia
Mining can have harmful effects on surrounding surface and groundwater. If proper precautions are not taken, unnaturally high concentrations of chemicals, such as arsenic, sulfuric acid, and mercurycan spread over a significant area of surface or subsurface water. Large amounts of water used for mine drainage, mine cooling, aqueous extraction and other mining processes increases the potential for these chemicals to contaminate ground and surface water. As mining produces copious amounts of waste water, dispos…Mining - Wikipedia,Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agri…Automated mining - Wikipedia,Teleoperated mining equipment refers to mining vehicles that are controlled by an operator at a remote location with the use of cameras, sensors, and possibly additional positioning software. Teleoperation allows an operator to further remove themselves from the mining location and control a vehicle from a more protected environment. Joysticks or other handheld controls are still used to control theCauses, Effects and Solutions for Mining - E&C,To protect the environmental system from the adverse effects of mining, states and governments have to install enough nature reserves so that animals and plants are protected from harmful human interventions. Nature reserves are crucial for animals and plant species to reproduce since they provide and ensure their natural living conditions. Thus, nature reserves are another measure to mitigate the adverse effects of miningThe Ways To Reduce Negative Effects Of Mining Activities,,By analytically examining the impacts of mining on ecosystem, it is still promising to diminish the negative effects of mining. 6. Creating system and mining guide to develop environmental performance that must be obeyed by the mining companies and various penalties who are failed to obey. At this point, the government has power to control the mining activities. 7. Capturing modern and,Open-pit mining - Wikipedia,Hydrology in mining. Open pit mines operating in an area with heavy groundwater features may eventually face hydrology-related problems. This includes heaving and bursting of the mine floor due to excessive uplift pressure. A groundwater control system must be installed to fix problems caused by hydrology. The formation of an appropriate open pit slope design, changes throughout the life of a mine.
