202321 This study was conducted in two adjacent opencast coal mines, ‘X’ and ‘Y’, of Mahanadi Coalfields Limited, Odisha, India. The range of surface miner utilisation in both mines, ‘X’ and202174 Coal overburden strata (OBS) vary in thickness, geochemical composition, and physical properties from stratum to stratum. Here, we enumerated the cultivable bacterial diversity and their distribution in different OBS taken from the opencast mining of Tikok colliery, Assam. The pH of the coal OBS ranged from 2.46 to 7.93, but 73% of the Heavy metal tolerance of bacterial isolates associated with overburden202351 The area of damaged land is 0.22 hm 2 per 10000 t coal mining in China's opencast coal mine, which leads to the direct excavation of 0.12 hm 2 land area, the dump occupies 0.10 hm 2 land area, and the dump area accounts for about 50% of the total area of damaged land.

2013417 Results and analysis. Based on the vegetation types and their biomasses, the carbon sink volume of the Heidaigou opencast mine area was 5,990,016.2 t in 2010, and the value of the carbon sinks was approximately $898.50 million. The main vegetation type was Stipa bungeana grassland prior to mining in 1987.2011323 Wardha Valley Coalfield (WVC) is a NW–SE elongated structural basin with its coal bearing zone spreading over an area of 800 sq km along a length of 116 km situated towards the south of the city of Nagpur in the central region of India (Fig. 1).This coalfield has around 40 opencast coal mines, which are largely of medium scale type Slope Failures in the Opencast Coal Mines of Wardha Valley سلسلة لجاكرتا كسارة الحجر. شاشة كسارة الحجر للبيع. شاشة كسارة الحجر للبيع كسارات الغسيل مبيعات محطسلسلة لجاكرتا كسارة الحجر GitHubاحصل على السعر
201959 China is the largest coal producer and consumer in the world. In recent years, the number of opencast coal-mining has increased, and mainly distributed in northwestern China, with weak ecological environments. Opencast coal-mining can cause huge interference to the soil and vegetation and seriously influence the local ecological 2023101 Coal is the major source of power in India and world over.
