The Jharia coalfield is the most important and active minig region; it experiences groundwater inflow and affects groundwater levels in overlying aquifers, and it provides the basis for a conceptual model of the hydrogeological impacts of coal mining. The several sandstone aquifers of the overburden are separated by aquitards that limit vertical …

Starting from its excavation to loading and unloading, coal produces dusts and radiation which have a direct negative impact on the ecology, biodiversity, and health of the surrounding communities. 17 During drilling, blasting, sizing, and transportation, the release of total suspended particulate (TSP) matter and inhalable particulate matter (PM …

The environmental impacts of open cast mining operations have been addressed. 24,25,26 Ahmad et al (2014) 27 studied those environmental parameters which were of special concern to the health of …

Glory hole mining is a method where the mineral is excavated in small open pits but is transported to the surface through underground excavations and transport system. Nearly 70% of the mineral production in the world comes by opencast mining and in India this method of mining accounts for nearly 75% of our mineral output.

Underground coal production in India shows a declining trend, and several underground mines are closed every year. However, 60% of the total coal production in the world is from underground mines, …

The Wulantuga open-cast germanium coal mine area (43°56′57.86″ N, 115°54′37.36″ E), covering an area of 2.2 km 2 [21,22], is located in the southwest of the Shengli Coalfield (with a total area of 342 km 2 ) in northeastern Inner Mongolia, northern China . The germanium-rich coal in the open-cast mine has been mined since 1997.

Allowing private commercial miners was a major move, and its positive effects extend beyond the coal industry. It is good that they have turned their attention to the neglected and loss-making underground mining, whose share in total coal production in the country had dropped from close to eight per cent in 2014-15 to less than four per …

A major part of iron ore, non-ferrous metals, brown coal, building materials and minerals for industry is being excavated in open-cast mines. This type of mining has a deep impact on the natural strata. Open-cast mining changes geological, hydrological and geotechnical conditions. It influences the existing ecological system and landscape.

Environmental impact assessment (EIA) follow-up in India is essentially regulator-driven. This article explores the role of the regulating agencies within the coal mining sector in India to ...

As a result, the collected coal dust from opencast mining would pollute the air, affecting the flora and wildlife in and around the mining sites and posing serious health risks (Pandey et al ...

This review presents a systematic synthesis of the various methods and measures that have been used to investigate the effects of coal mining in India. A total of 87 peer-reviewed articles were collected for each year from 1970 to 2014 using a keyword based search. The articles compiled were analyzed and categorized according to the …

Coal is the major source of energy which contributes 57.3% of the total energy supply in India (CEA 2018), and consumes about 8% of the total coal in the world (Yao et al. 2015).The rapid expansion of coal mining to meet the energy demand leads to severe vegetation loss, land degradation, and finally results in the release of toxic metals …

Abstract and Figures. Proper design of waste dumps in open cast mines is essential to avoid any large-scale dump failure which may have significant impacts on safety as well as the economics of an ...

Medapalli Open Cast Project (MOCP) owned by M/s Singareni Collieries Company Limited (SCCL), Andhra Pradesh, India where "Highwall mining" is practiced lies in the immediate vicinity of a large perennial river, 'Godavari'. The mine and river, which are only 140–150 m apart, an artificially constructed embankment, built above highest flood …

Open cast or surface mining is dominant in India and it not only alters the nature of groundwater–surface water interactions but also contributes to major air …

The study aims to simulate the stage-wise, year-wise mine seepage predictions and the corresponding impact on the groundwater regime (drawdown and heads) in accordance with the approved mine plan for certain coal mines in Central India. To that end, the optimized and efficient watershed area of 997.61 km2 has been …

Around 70% of the country's coal reserves are amenable to UG mining, which delivers several advantages. In FY22, out of 622.6 million tonnes of coal mined, nearly 96%, or 597 million tonnes, was opencast (OC) coal. India accounts for 12.5% of global coal consumption. Close to 70% of the country's electricity generation is coal-based.
