Dynamite was invented by Swedish chemist and engineer Alfred Nobel in the late 19th century as a safe way of using nitroglycerin as a demolition agent. Nobel stabilized nitroglycerin by mixing it with diatomaceous earth, the fossilized shells of diatoms. Dynamite has to be detonated using a blasting cap. Used as a ...

Initiation Systems. Electronic detonators utilize microchips to deliver more precise timing to improve blasting results. Our electronic initiation systems are rugged, reliable and safe. These important advances in technology enable users to achieve the benefits of accuracy with the easy connections of traditional nonelectric shock tube systems.
In 1867, Alfred Nobel stabilized nitroglycerin by adding diatomaceous earth to make dynamite. It was safer than black powder and much more powerful. Dynamite came to be widely used in mining and construction, and it expedited the building of roads, railways, tunnels, canals and other construction projects worldwide in the second half of the 1800s.
Dynamite is a powerful explosive that has been used for various purposes throughout history. From construction to mining, dynamite has played a crucial role in shaping the world we live in today.

Walter Vicinelly, state Commissioner of Deep Mine Safety said dynamite used in mining could have touched off a methane gas explosion.
explosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical reaction, such as overloading a container with compressed air. Such a device has some …
Background: Our previous infodemiological study was performed by manually mining health-effect data associated with electronic cigarettes (ECs) from online forums. Manual mining is time consuming and limits the number of posts that can be retrieved.
Read this passage: Dynamite is an explosive used mainly in demolition and mining. Invented in 1866 by Alfred Nobel, dynamite is derived from nitroglycerin, a highly poisonous explosive liquid, and is highly regulated to prevent accidental detonations.
When mining, dynamite is typically packed into drill holes for blasting or used to break up large pieces of ore before transportation or processing. The primary components of dynamite are nitroglycerin and a porous absorbent, which reduces its sensitivity to shock, heat, and light.
