Uranium from ores mined at the three mines - Jaduguda, Bhatin and Narwapahar (Jharkhand) - is processed in the mill and the waste emerges as tailings. The recorded radioactivity level in these tailings is very low, but to avoid any long-term effect of these tailings on the atmosphere, humans, cattle as well as native flora and fauna, the tailings are covered with 30 cm layer of soil.
14 mining leases were visited in five forest divisions (Satna, Balaghat, Bhandara, Kolhapur and Vadodara) spread across three states namely Madhya Pradesh, Maharashtra and Gujarat. The study included various minerals like Limestone, Bauxite, Ochre, Manganese, Fluorspar and Kyanite. (Out of 14 mining leases 3 were for underground mining and 11 were for opencast mining.)
In India the mining operations have degraded significant area of land and have replaced the ecosystem of the mined out areas with the undesirable waste materials in form of overburden dumps. The process of coal extraction drastically alters the physical and biological nature of the mined out areas, so the land
Mine spoils are sub-soil material produced as a byproduct of mining activity. Virtually being a sub-soil material, mine spoils are physically, nutritionally and microbiologically impoverished habitats, thwarting the establishment and growth of plants species.
Central Ground Water Board (CGWB) organised two-day workshop on Water Management and Hydrochemistry in the auditorium of Wadia Institute of Himalayan Geology. The participating experts strongly recommended for proper rehabilitation of the areas of land degenerated by mining in the State.
Vegetation condition monitoring has been done from 1975 to 2000 in the waste dump of Haizhou opencast coalmine area, China, using remote sensing techniques with the objective of improving our understanding of the temporal and spatial variation of vegetation recovery in the mining dump.
Text of the Supreme Court judgment on mining in the Aravalli Hill Range of Haryana as on 8th October, 2009 . The apex court granted conditional permission for resumption of mining of minor minerals in the Aravalli region of Faridabad and Palwal.
Thousands of villagers in Parbatipur upazila laid siege to Barapukuria Coal Mining Company Ltd for two hours yesterday seeking compensations for their properties taken away, or land subsided due to mining.
The protesters also asked for permanent resettlement of the villagers affected by mining activities.
The mine-degraded lands initially lack viable mycorrhizal fungal population, and thus, the establishment of a vegetative community will be delayed. Mycorrhiza inoculation can enhance productivity of degraded land by increasing drought tolerance of plants and phosphorus availability, which are the main two limiting factors for plant establishment.
