1. Exposure to coal mine dust causes various pulmonary diseases, including coal workers’ pneumoconiosis (CWP) and chronic obstructive pulmonary disease (COPD). 2. Coal miners are also exposed to crystalline silica dust, which causes silicosis, COPD, and other diseases.
What happens when you breathe in coal dust?
The inhalation and accumulation of coal dust into the lungs increases the risk of developing chronic bronchitis and chronic obstructive pulmonary disease (COPD).
Does coal dust cause cancer?
These findings are surprising since in addition to coal dust, miners are exposed to other substances that are widely recognised as causing respiratory cancer in humans, most notably silica,1 but also diesel exhaust and radon gas.
How do I get rid of coal dust?
Using a medium stiffness 2″ bristle brush together with the vacuum should remove more than 95% of the residual coal dust. Once an initial cleaning is completed, a 2nd pass using compressed air can be used to blast loose nearly all remaining dust, while sucking it into the HEPA vacuum.
How does coal dust affect the lungs?
It is common in coal miners and others who work with coal. It is similar to both silicosis from inhaling silica dust and asbestosis from inhaling asbestos dust. Inhaled coal dust progressively builds up in the lungs and leads to inflammation, fibrosis, and in worse cases, necrosis.
Do lungs clean themselves of dust?
Besides macrophages, the lungs have another system for the removal of dust. The lungs can react to the presence of germ-bearing particles by producing certain proteins. These proteins attach to particles to neutralize them. Dusts are tiny solid particles scattered or suspended in the air.

1. North Antelope Rochelle, US – 1.7 billion tonnes. The largest coal mine in the world by reserves is the North Antelope Rochelle coal mine in the Powder River Basin of Wyoming, US. The mine was estimated to contain more than 1.7 billion tonnes of recoverable coal as of December 2018.
Can you die from inhaling coal?
Black lung disease is considered a job-related illness. You get it when you inhale coal dust over a long period of time. Because it mainly affects coal miners, it’s also known as coal workers’ pneumoconiosis (CWP). As you breathe in coal dust, particles settle into your airways and lungs.
Is Black Lung curable?
There is no cure for black lung disease – we can only treat symptoms. Medications, such as inhaled steroids, can help patients breathe more easily. More severe cases can require oxygen and possibly lung transplants.
Can you burn coal dust?
Preventive procedures, however, must rely on fundamental knowledge concerning the behavior of coal dust combustion. … In addition, it is known that coal particles do not always burn simply as shrinking spheres, but can burn internally and form cenospheres (hollow spheres) as well.
Does coal explode?
Mine explosions can also be triggered when fine particles of coal dust come into contact with a source of heat. While methane is easier to ignite, the explosion pressure and heat value of methane is not as high as coal dust. In most cases, dust explosions are first caused by methane explosions, said Luo.
What causes coal dust explosions?
Coal mine explosions are generally caused by either methane or coal dust. … Explosions happen when the methane comes in contact with a heat source. The combustion process causes air inside the mine to expand which can create a shock wave. The most common method to control methane levels in coal mines is ventilation.

Can you get sick from breathing in dust?
You may not think it’s a big deal when you breathe in dust, but for some people, it could bring on a lung disease called hypersensitivity pneumonitis. It’s an allergic reaction to particles in the dust, and it can cause symptoms like coughing and shortness of breath.
