the impact of coal mining
Coal as an energy source and its impacts on human health
Coal contains rare earth elements and carbon nanoparticles that can be useful to high-technology (Nano- and Microtechnology) (Dai et al., 2016; Silva et al., Streams affected by coal mining averaged one-third (32%) lower taxonomic richness and one-half (53%) lower total abundance than unmined streams, Impact of coal mining on stream biodiversity in the US and

Coal mining and environmental sustainability in South Africa:
This study investigates the effects of coal mining on environmental sustainability in South Africa in relation to the moderating role of institutions. To achieve the study’s objectives, the fully modified least square (FMOLS), dynamic least squares (DOLS), canonical cointegrating regression (CCR), Bayer-Hanck cointegration and Toda This paper throws light on the bibliometric review of the impact of coal mining in India over the past 50 years, emphasizing environmental, especially water-related impacts. The data were refined from the Web of Science database and analyzed in a bibliometric map visualization software tool, VOSviewer, to grasp the research focus, Exploring the last 50 years of Indian research on the impact of coal

Impact of coal mining on groundwater of Luohe Formation in
The impact of coal mining on groundwater depends on the water conductor and the source of water. In coal mining, three fault zones are formed in the overburden strata, namely the caving zone, the fracture zone, and the curved subsidence zone (Li 2019; Li et al. 2020). The water-conducting fracture zone is the main water-conducting channel The health implications of coal mining and utilization are considerable and diverse. Exposure to particulate matter, heavy metals, and other harmful pollutants from coal-related activities can result in respiratory diseases, cardiovascular issues, and even long-term chronic health conditions.Environmental impact and health risk assessment due to coal mining

Effects of Underground Coal Mining on Soil Spatial Water
The impact of coal mining subsidence on surface ecology involves the influence of several ecological elements such as water, soil, and vegetation, which is systematic and complex. Given the unclear understanding of the synergistic change patterns of the water–soil–vegetation ecological elements in the influence of coal mining in the west, this The impacts of underground coal mining on the water resource quantity have also been investigated. To prevent groundwater loss during mining, Bai et al. (2022) proposed a new coal mining method to reduce the impact on the nearby aquifer. Liu et al. (2019) established zoning and management methods for phreatic water affected by Prediction and zoning of the impact of underground coal mining

Coal mining FutureCoal
Longwall mining involves the full extraction of coal from a section of the seam, or ‘face’ using mechanical shearers. The coal ‘face’ can vary in length from 100-350m. Self-advancing, hydraulically-powered supports temporarily hold up the roof while coal is extracted. When coal has been extracted from the area, the roof is allowed toCoal mining and soil-water conservation are the two major human interventions on the Loess Plateau in China. Analyzing their impacts on hydrological processes is of great significance for sustainable water resource management.

Economically, surface mining is a cheaper option for extracting coal than underground mining. About two and a half times as much coal can be extracted per worker, per hour, than is possible with Despite the trend of a transition to “clean” energy, the coal industry still plays a significant role in the global economy. The constant need for raw materials and energy for production leads to an An Overview of Carbon Footprint of Coal Mining

An investigation into the disturbance effects of coal mining
Coal mining disturbs surface ecosystems in coal mining subsidence areas. Based on the groundwater–surface composite ecosystem analysis, we constructed an ecological disturbance evaluation index system (18 indices) in a coal mining subsidence area using the analytic hierarchy process (AHP). Taking the Nalinhe mining area in Exposure to dust from the mining environment has historically resulted in epidemic levels of mortality and morbidity from pneumoconiotic diseases such as silicosis, coal workers’ pneumoconiosis (CWP), and asbestosis. Studies have shown that CWP remains a critical issue at collieries across the globe, with some countries facing The impact of coal mine dust characteristics on pathways to
