The environmental impacts of mining activities are discussed based on their implications on various aspects of environmental resources, namely: Unsustainable mining and overconsumption of resources, environmental degradation and pollution, mining disasters, risk of climate change disasters, loss of species and degradation of critical ecosystems ...
Since 1956, Harrison Gypsum has been a prominent figure in the gypsum mining sector. The company has made a name for itself by maintaining a consistent and high level of product quality. They operate four gypsum mines in Oklahoma, one mine in North Texas and three limestone mines – two in Oklahoma and one in South Kansas.
Gypsum mining can lead to various environmental impacts. The extraction process often involves clearing large areas of land, resulting in habitat destruction and loss of biodiversity. The removal of vegetation and …
1. Introduction. As typical brittle rock masses, gypsum mines are often produced in the form of thick and large layers with good integrity and excellent stability; therefore, room-and-pillar mining is often used [].In the production process of the mine, the multilevel goaf left by in the room-and-pillar mining method exhibits good stability …

Genotoxic impact, i.e. the level of primary DNA damage in haemocytes, was also investigated, since gypsum mining activities result in wastewaters contaminated with heavy metals. For this purpose, water and sediment samples and amphipods were collected at a site downstream from a gypsum mine, in the Kosovčica River, and at a reference …

Calcium Sulphate Dihydrate (Gypsum) is commonly hydrated by groundwater. The UK is largely self-sufficient in gypsum. The material can be found in seams in the Pennines and the Midlands, but the biggest source of extraction is in East Sussex where mining extracts some 100,000 tonnes of gypsum a year from 100 m below the High Weald.
"[Gypsum mining] has had harmful effects. Medical experts say mining can have [a] serious impact on [the] health of people and this may cause damage to their lungs," says Mubashir Ahmad, coordinator of CEE Himalaya. According to the organization, suspended particulate matter has increased greatly in the area, due to the mining of …
