How do I get rid of coal dust?

How do you control coal dust?

Ventilating air and water sprays remain the basis of dust control strategies for both longwall and continuous mining operations, and the level of application for these controls continues to increase. In addition, new technologies are emerging that have the potential to further reduce dust levels.

What can you do with coal dust?

Energy generation

For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation.

How bad is breathing in coal dust?

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 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.

How do you stop coal dust explosions?

Coal dust explosions in underground coal mines are prevented by generous application of rock dust (usually limestone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents flame propagation by acting as a thermal inhibitor or heat sink.

What disease do coal miners get?

The two main types of pneumoconioses that affect miners are coal workers’ pneumoconiosis (CWP), commonly called black lung, and silicosis. CWP is associated with coal mining, but silicosis can affect workers in many types of mines and quarries, including coal mines.

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.

Why is there a danger of explosions in coal mines?

There is an increased risk of explosion in enclosed places like coal mines because flammable or combustible materials may become ignited by pressure that have built up inside the mines. Apart from this risk, the mines giving way or collapsing remain possible that could result in several fatalities and injuries.
