Pulverkiste

Pulverkiste, also known as a powder keg, is a type of explosive device used in mining and quarrying to facilitate the controlled demolition of rock. It consists of a cylindrical container made of steel or other durable materials, filled with a mixture of explosive powder and a detonator. The powder keg is designed to be placed in a borehole drilled into the rock, with the detonator positioned to initiate the explosion.

The operation of a pulverkiste involves several steps. First, a borehole is drilled into the rock, typically using a drilling rig. The pulverkiste is then lowered into the borehole, and the detonator is positioned at the desired depth. Once the pulverkiste is in place, the detonator is activated, initiating the explosion of the explosive powder. The force of the explosion fractures the rock, allowing it to be removed more easily.

Pulverkisten are commonly used in the mining and quarrying industries due to their ability to safely and efficiently break up large volumes of rock. They are particularly useful in situations where traditional blasting methods are not feasible, such as in confined spaces or when working with sensitive materials. However, the use of pulverkisten is subject to strict safety regulations to prevent accidents and ensure the well-being of workers.

In summary, a pulverkiste is a specialized explosive device used in mining and quarrying to facilitate the controlled demolition of rock. It consists of a cylindrical container filled with explosive powder and a detonator, and is placed in a borehole drilled into the rock. The operation of a pulverkiste involves several steps, including drilling, positioning, and detonation, and is subject to strict safety regulations.
