by Sahana Ghosh on 29 November 2018. India's National Green Tribunal in 2014 banned rat hole mining of coal and its transportation over concerns for the environment and labour conditions in the tribal-majority state of Meghalaya. Rat hole mining of coal is an unscientific practice to extract coal through narrow tunnels into the ground.Web
The types of coastal mining activities in the WIO countries considered in the context of the chapter are: • Quarrying of coral rock and limestone for cement manufacturing and course aggregates for concrete and road building; • Artisanal sand mining from the catchment, flood-plains, river banks, estuaries and lagoons;Web
Lowering water tables prior to mining, i.e. dewatering, is done to maintain stable slopes and safe working conditions. However, aquifer dewatering poses considerable hydrological risks to regional groundwater by creating extensive and prolonged cones of depression, lowering the water table, and causing land subsidence and water …Web

Kumar et al. (2022) investigated the concentrations of primordial radionuclides in soil samples taken from mining and non-mining areas in Ariyalur taluk, Tamil Nadu, South India. To get the measurements that were most significant to groundwater quality, the same dataset was evaluated using three distinct methodologies.Web
Rock fragmentation due to blasting depends upon many parameters. The properties of the explosive are one of them. In limestone quarries, ammonium nitrate–fuel oil (ANFO) or site mixed emulsion (SME) are generally used for rock fragmentation. Both these explosives cause substantial changes in the breakage mechanism of rockmass …Web

Explores impact of mining on deforestation across 314 districts of India for 2001–2014. Impact of key minerals such as iron, coal, bauxite, limestone and granite is assessed. Coal, iron or limestone producing districts suffered 450 sq km of extra forest cover loss. Districts not producing any of the key minerals had 350 km 2 lower forest loss.Web
large volumes of toxic tailings of enrichment, pollution of soil, surface and groundwater. The environmental situation in the area of activity of the plant can be characterized as a crisis. The Bilyutinsky mine of chemically pure limestone is characterized by the largest mechanical disturbances of the natural environment.Web
Excavation of minerals from the earth's surface leads to extensive forest loss and the extent of deforestation is higher in the case of illegal mining activities (Ranjan 2018). In India, an average 450 km 2 higher loss of forest cover is observed in coal, iron or limestone producing districts compared to non-producing minerals (Ranjan 2019).Web
