Once the area is clear, a second explosive or shaped charge is placed on the device by explosive ordinance disposal (EOD or police bomb disposal) personnel, either manually or with a bomb disposal robot, and detonated remotely. The controlled explosion should also detonate or disable the suspected bomb.

Blowdown is an internationally broadcast documentary television series that follows a team of explosive demolition experts as they prepare and implode iconic, complex and challenging structures around the world.
Drilling and blasting currently utilizes many different varieties of explosives with different compositions and performance properties. Higher velocity explosives are used for relatively hard rock in order to shatter and break the rock, while low velocity explosives are used in soft rocks to generate more gas pressure and a greater heaving effect.
On September 24, 1876, the Corps used 50,000 pounds (23,000 kg) of explosives to blast the rocks, which was followed by further blasting. [2] The process was started by excavating under Hallets reef from Astoria. Cornish miners, assisted by steam drills, dug galleries under the reef, which were then interconnected. They later drilled holes for ...
