Explosives: What are They and What are they used For?
Explosives are chemical compounds capable of releasing large amounts of energy rapidly, usually accompanied by a loud sound and bright light. These compounds are used in a variety of industries for demolition, mining, military, and more. While explosives are useful, they can be incredibly dangerous if not handled with care. Let’s take a look at explosives and how they are used in an industrial setting.
Types of Explosives
Explosives are a broad category of compounds, composed of both organic and inorganic substances. The most common type of explosive is dynamite, which is made of nitroglycerin, a powerful organic compound related to the more mild nitroglycerin tablets. Dynamite is usually packed with additives such as sawdust, gravel, or powdered mineral to increase its power.
Inorganic explosives include silver azide, lead azide, tetryl, and ammonium nitrate based compounds, such as ANFO (Ammonium Nitrate Fuel Oil). These materials can be quite hazardous, due to their nature, but are used in industry due to their cost and reliability.
Applications of Explosives
Explosives are used in a variety of industries, including mining, military, and demolition.
Mining
Explosives are used extensively in the mining industry, both for digging tunnels and for extraction of ores. Explosives are widely used in open-pit and surface mining operations, as well as in underground kiss mining operations. Using explosives for mining operations can make the extraction of resources faster and more efficient.
Military
Explosives are used in a variety of military applications. Military explosives include high explosives, such as TNT, C4, and ANFO, and low explosives, such as black powder. High explosives are typically used in detonations, mines, shells, grenades, and missiles. Low explosives are commonly used as propellants in firearms and rockets.
Demolition
Explosives are frequently used in demolition operations to bring down old structures, such as buildings and bridges, quickly and safely. Different types of explosives can be used depending on the application, such as dynamite or black powder for small-scale operations and ANFO for larger operations.
Safety Considerations
Explosives can be incredibly dangerous, and it is important to treat them with respect and caution. It is essential to always follow safety protocols and local regulations when handling or using explosives.
The storage of explosives is highly regulated in most countries, and must follow strict safety protocols. Explosives are usually stored in magazines, which are designed to protect from the elements and keep them from mixing by mistake.
It is also essential to take proper precautions when handling or using explosives. All users must be properly trained in the use of explosives and must follow all safety protocols.
Conclusion
Explosives are powerful chemical compounds used in a variety of industries. They can be used in mining, demolition, and military applications, but must always be handled with care and respect. By following safety protocols and regulations, explosives can be safely used to facilitate operations in a variety of fields.
