Coal is an important energy source, but its use affects regional air quality and global climate. This study finds that coal mining reduces the diversity and number of stream animals and that these ...
Introduction. Nigerian Coal Corporation started mining in 1916 at Onyeama Coalfield, Enugu (Onwukeme Citation 1995), and in October 1977, their operations became mechanized (Asogwa Citation 1988).A literature search was unable to find any work carried out on environmental impact of mineral exploitation at a coal mined site in south …
Due to its high energy generation potential, coal is widely used in power generation in different countries. Although, the presence of carbon, hydrogen and sulfur in coal facilitates the energy generation in coal combustion, some pollutants including COx, SOx, NOx, particulate matter (PM) and heavy metals are accumulated in air and water …
The main operational lifecycle and development of the mine consists of exploration and feasibility, planning and construction, operation, and closure stages (Suh et al., 2017) and each stage involves various hydrological and environmental impacts (HEIs).The duration of each stage may differ due to the management and development …

Mexico generated 86.27 TWh or 26.7% of its electricity from clean energy resources in 2021. To meet the 35% clean energy target in 2024, Mexico needs at least 128.83 TWh …
According to the National Inventory of Greenhouse Gases (GHG), issued by the INECC (2015) with information in 2013. Mexico emitted 665,304.62 Gg of …
In the case of Mexico and South Africa, for example, coal production is concentrated in one particular area of the countries where they face similar social, economical and environmental problems. In contrast, the coal industry in Chile is spread throughout the country, but NGOs and civil society in Mexico and Chile face the same …
Mining and the exploitation of natural resources has long been seen as a mixed blessing for the development of an economic area.Rich endowments of resources provide cheap access to important inputs in the production process, which can lead to increased employment and higher incomes (Black, McKinnish, and Sanders Reference …
Except for bauxite, iron and manganese, which are listed as ores (gross weight), metal production is reported as metal content (net weight). In order to construct a homogeneous measure of extracted crude ore that is used as an input from the natural environment to the economic system, we applied country- and commodity-specific …
Mexico once embraced renewable energy. Now President Andrés Manuel López Obrador is doubling down on dirty fossil fuels such as coal.

The use of fossil fuels—coal, oil, and natural gas—results in significant climate, environmental, and health costs that are not reflected in market prices. ... the 2010 BP Deepwater Horizon spill, released 134 million gallons of oil into the Gulf of Mexico, killing 11 people and countless birds, turtles ... The environmental and health ...
The mines that dot the State of Coahuila operate under a constant threat of roof collapse, water flooding, and methane explosions. The coalfields of the Sabinas …
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released …
This study investigates the vertical distribution of pollutants emitted from coal yards using unmanned aerial vehicles (UAVs). Vertical concentration measurements of black carbon (BC) and particulate matter (PM) in a range of 1 m to 100 m above ground level (AGL) in the central coal yard showed clear spatial patterns and gradients of these …
A recent study shows that large piles of coal produce measurable quantities of fine particulate air pollution within a 25-mile radius. Covering coal trains and storage piles could reduce the problem.
With the continual advancement of coal resource development, the comprehensive utilization of coal gangue as a by-product encounters certain constraints. A substantial amount of untreated coal gangue is openly stored, particularly acidic gangue exposed to rainfall. The leaching effect of acidic solutions, containing heavy metal ions …
Mexico City was once named as the world's most polluted city in the world, but according to IQAir, a Swiss company which keeps track of the air quality of cities around the globe, Mexico City has now dropped down to the 917th most polluted city in the world in 2021. Though its concentration of airborne particles (PM 2.5) still currently exceeds the …
Coal. As of January 2021, Mexico had 5,378MW of operating coal plants, according to the Global Coal Plant Tracker. This accounts for 4% of the nation's total power generation. Mexico's electricity production from coal halved compared to the previous year in 2020, the largest percentage reduction of any G20 country.
The second chapter focuses on the socio-environmental impacts of the coal industry in the country and points out the very serious human rights violations resulting from coal mining. The third chapter outlines the elements necessary to implement a plan that ensures the exit of coal under a climate justice and human rights approach. This …
The extraction of coal and coal seam gas (CSG) will generate produced water that, if not adequately treated, will pollute surface and groundwater systems. In Australia, the discharge of produced water from coal mining and related activities is regulated by the state environment agency through a pollution licence. This licence …
The environmental impact assessment in Mexico, according to the Ministry of Environment and Natural Resources, is an instrument of environmental policy, whose objective is to prevent, mitigate and restore environmental damage as well as the regulation of works or activities, in order to avoid or reduce their negative impact on the …
