Abstract. The impacts of quarrying of the gypsum deposits on the environment at Maqna, Tabuk, were evaluated by intensive field studies including in situ testing, mapping and sampling of gypsum and well water. Field and laboratory tests were made to determine the engineering properties including tensile and compressive strengths, unit weight, fracture spacing and the rock quality designation

Calcium(II) sulfate dihydrate, Gypsum stone, Hydrated calcium sulfate, Mineral white [Note: Gypsum is the dihydrate form of calcium sulfate; Plaster of Paris is the hemihydrate form.] White or nearly white, odorless, crystalline solid
Mar 27, 2021 Large-area goafs in a gypsum mine tend to collapse after 10 or more years, but the influencing factors are still unclear, and the effects of multiple factors have not been comprehensively considered. In this study, the failure mechanism and collapse mode of the room-pillar goaf structure were analyzed, and the uniaxial compressive strength tests of the pillars under different conditions were
Mining is a human activity with a long history. It has a wide. and diverse range of direct and indirect geomorphic effects. by creating unique types of excavated and accumulated land-. forms and
Specific regulations for the mining sector have also been enacted to deal with the environmental effects of mining operations. In Spain, and also in Catalonia, the mining regime is regulated by the Mines Act (Act 22/1973), of July 21st, and by Royal Decree 2857/1978, of August 25th. These two regulations already referred to environmental
Oct 31, 2018 Phosphate mining is a major industry in Florida, but it’s also a major source of pollution, responsible for red tide, toxic algal blooms and killing wildlife. In the northern part of the state
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks
Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat

Gypsum miners had finger dysfunction and muscle numbness, joint pain (29.2%, 88/301) and chest pain and breathing difficulties (17.6%, 53/301). Followed by tinnitus, auricle pus, running water (4.7%, 14/301), abnormal muscle tension (2.7%, 8/301)
The primary environmental impacts of raw gypsum are habitat disruption from mining, energy... Read more Environmental impacts of the gypsum mining operation at Maqna
Results indicated significant indirect influence of mining activities on water quality parameters. Even though chemical contamination was insignificant, the bacteriological concentration indirectly arising from gypsum mining was higher than WHO (2006) guide values and therefore exposed the public to waterborne diseases
Environmental effects of gypsum quarry CASA CLIMA. Sep 10, 2012 Gypsum mining results in environmental hazard as well, says Gurcharan Singh, an environmentalist and former mass media officer for the Directorate of Ecology, Environment and Remote Sensing. “Gypsum mining can lead to destabilizing slopes [and] that can lead to soil erosion
