In recent years, landslides induced by underground mining have attracted much attention as they cause great harm and early warning signals are difficult to detect. The key work of the early warning of a mining landslide is to clarify its initiation mechanism and evolution process. Due to the complexity of the deformation and failure of the goaf …
Coal is a major energy source in China. Though the proportion of coal consumption in the country's energy mix has generally decreased from 2011 to 2020, excluding Hong Kong, Macao, and Taiwan, it still constitutes more than half of the total (Fig. 1).However, coal production is a multifaceted and dangerous undertaking that involves …
Coal has long been a reliable source of US energy, but it comes with tremendous costs because it is incredibly dirty. The same chemistry that enables coal to produce energy—the breaking down of …
Coal mining jobs are going away because of the same productivity gains that have led to fewer manufacturing jobs across the country — workers can produce more coal per hour, meaning fewer workers are needed to …
1. Introduction. Coal is a major source of air pollution and harms public health. Many studies have examined the impact of burning coal (Cesur et al., 2017, Clay et al., 2016, Beach and Hanlon, 2018, Johnsen et al., 2019), but few address the fact that producing coal also generates pollution.Coal mining generates pollution in three ways.
The effects of mining coal on the environment. There are 2 ways to mine coal – Strip Mining and Underground Mining – both ways have their own impact to the environment and health. ... Health Hazards: Coal dust inhalation can cause black lung disease. Miners and those who live in nearby towns are the most affected. Cardiopulmonary disease ...
Proving that accidents in mines, where occupational health and safety measures are not implemented and inspections are not done properly or at all, are caused by the fact that production is imposed to be carried out in the fastest, cheapest, and most profitable way will allow us to take steps to prevent further mine accidents.
Black lung disease is a job-related illness caused by inhaling coal dust over a long period of time. The condition mainly affects coal miners and is also known as coal workers' pneumoconiosis (CWP).
We fill this gap by estimating the causal effects of coal mining on ambient air pollution and all-age mortality based on a sample of underground coal mines in China. …
Methane emissions from coal mining are well studied and expected to reach approximately 784 Mt of CO 2-equivalent (CO 2 e) by 2030 1.However, since coal mining itself is being directly targeted in ...
Coal mining destroys natural habitats, not only through deforestation and mountaintop removal, but also by contaminating the surrounding land and waterways. This, in turn, can harm or kill plants and animals and disrupt entire ecosystems. Coal mining can also cause coal-seam fires, when outcrops or underground coal seams catch fire.
Pneumoconioses (meaning dusty lung) can cause impairment, ... CWP, commonly called black lung, affects workers in coal mining. Silicosis can affect workers in many types of mines and quarries, including coal mines. Medical treatment cannot cure these diseases, so preventing them – through controlling respirable dust exposure – is …
Effects of coal mining. Surface mines (sometimes called strip mines) were the source of about 63% of the coal mined in the United States in 2022. These mining …
The massive volume of dust produced by coal mine activities causes respiratory concerns for workers and machinery maintenance challenges. Dust can also contribute to an explosive situation. Every year, people are injured or killed as a result of accidents or health problems caused by coal dust exposure. Mining businesses can …
When humans do not receive enough oxygen to the brain it can cause headaches, nausea, dizziness, and can ultimately result in death when the oxygen concentration drops below 6%. ... In coal mines, large quantities of CO is generated during the oxidation of coal, and during mine fires or explosions. It will then be present in what …

Coal workers' pneumoconiosis (CWP), commonly known as "black lung disease," occurs when coal dust is inhaled. Over time, continued exposure to the coal dust causes scarring in the lungs, impairing your ability to breathe. Considered an occupational lung disease, it is most common among coal miners.
When coal mines are no longer operated to produce coal, they are known as closed (or "abandoned") mines. Even though active mining no longer occurs, these abandoned mines can still produce significant methane emissions from diffuse vents, fissures, or boreholes. This methane can be deliberately extracted and used to generate …
This shows that even when not directly intervening with glaciers, mining activities can cause glacial decline, adding to the threat glaciers already face due to climate change. She also notes that "glaciers are an important water storage facility," describing how, on an annual cycle, glaciers freeze and melt, allowing runoff that downstream ...
The most common causes of accidents in coal mining are firedamp and dust explosions, landslips, mine fires, and technical failures related to transport and mechanization. An analysis of occupational accidents in the consideration of social and economic factors will let understand the real causes behind these accidents, which are said to happen ...
Acid mine drainage can release toxic levels of heavy metals into the environment. Learn about its causes, environmental impact, and possible solutions
From 1900–2006, 11,606 underground coal mine workers died in 513 U.S. underground coal mining disasters, with most disasters resulting from explosions Kowalski( -Trakofler, et al.,2009a). In 2007, 9 additional workers died in the Crandall Canyon disaster (Gates, et al. 2007a), bringing the total to 11,615 miners killed in 514 disasters.
Coal mining - Underground, Surface, & Drilling: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in …
This paper explores the root causes of coal mine accidents to clarify the characteristics of safety culture deficiencies and propose positive suggestions based on …
Coal mine dust causes a range of lung diseases, collectively called coal mine dust lung diseases. Examples include coal workers' pneumoconiosis (CWP, a dust-induced scarring lung disease commonly called black lung), chronic obstructive pulmonary disease (COPD), and lung function impairment. All of these cause substantial morbidity …
Methane explosions occur in mines when a buildup of methane gas, a byproduct of coal, comes into contact with a heat source, and there is not enough air to dilute the gas to levels below its...
In the United States, roughly 30 percent of all electricity comes from coal: the rest comes from natural gas, nuclear, and renewables like wind and solar. Most US coal comes from either above …

Examples include coal workers' pneumoconiosis (CWP), a dust-induced scarring lung disease commonly called black lung), chronic obstructive pulmonary disease (COPD), and lung function impairment. All of these cause substantial morbidity …
But only people who work in coal mines develop black lung disease. Among people who work in coal mines, black lung disease is somewhat common. Even after decades of knowing that coal mine dust can cause disease, black lung disease still affects about 16% of coal workers. And these rates are increasing.
Despite being crucial for meeting the world's energy demands, coal mining operations present considerable health risks, especially when it comes to exposure to coal dust. Longwall coal mining, an advanced technique, has considerably enhanced production but made dust control more difficult. Due to its explosive nature, coal dust …
