With mining activity predicted to expand, understanding the impacts of this habitat loss on wildlife is key to developing effective mitigation at new mine developments. Despite this, research into the impacts of open-pit mines in general, and

2024year6month1day Coal is a non-renewable primary energy source that plays a crucial role in facilitating socioeconomic advancement. Open-pit mining is the principal method of global coal mining, accounting for more than 80% of the total production (Dai et al., 2014).In 2018, the share of open-pit coal mine production in major coal-producing countries, such as

2021year8month20day Purpose There are a large number of open-pit coal mines in the world, and their dependent, heterogeneous dump sites are one of the world’s largest chronic waste concerns. The long-term existence of dumps is vulnerable to non-uniform deformation and erosion simultaneously, seriously threatening also the surrounding geological and

2023year4month11day The mine, one of Turkey’s largest open-pit gold mines, covers a total area of 393.54 ha, with 205.30 ha of current and new project units proposed in 2018. ... 109.85 hectares of forest and 5.30 hectares of agricultural area were degraded to establish the mine site. Mining activities destroyed 115.15 hectares of land cover (Table 5).

Mining activity changes the land-use pattern and alters the surface topography by increased surface erosion and excavations. If proper reclamation is not done, this can result in unaesthetic landscape. Open-pit mines must be filled with mine waste rock as reclaimed land. It can be filled with rain or floodwater for fisheries, water sports etc. (F)

2024year9month30day Water inflow was a very important problem in underground mining until James Watt invented the steam engine in the 18th century. After that, steam-driven pumps could be used to remove water from the deep mines of the day. Early lighting systems were of the open-flame type, consisting of candles or oil-wick lamps. In the latter type, coal oil,

2016year5month1day Degraded waste land produced by mining activities typically consists of: stripped areas (59%), open-pit mines (20%), tailings dams (13%), waste tips (5%) and land affected by mining subsidence (3%). During surface mining, 2–11 times more land is degraded than by underground mining (Miao and Marrs, 2000). The land-use types are

2020year7month23day Innovation plays a critical role in the mining industry as a tool to improve the efficiency of its processes, to reduce costs, but also to meet the increasing social and environmental concerns among communities and authorities. Technological progress has also been crucial to allow the exploitation of new deposits in more complex scenarios:
