Stump explosion

from Wikipedia, the free encyclopedia

Stump detonation refers to the detonation of a stump , i.e. a tree stump or a tree root, with an explosive charge in order to remove it.


The explosive ( gelatinous explosives , powdered explosives or emulsion explosives are often used) is usually brought into drill holes in or under the stump. For this purpose, depending on the size of the stump, a few holes are drilled into the wood and provided with explosive charges. The aim here is to shred the stump to such an extent that manual removal is possible.

Another possibility is to blast the stump through boreholes that are driven into the ground directly under the roots. There is also the possibility of drilling only one borehole and by igniting a smaller amount of explosives to prepare the space for the subsequent introduction of larger amounts of explosives ("pre-boilers"). The explosive charges ignited there lift the stump and loosen the soil or throw it out.


Nowadays, stumps are only blasted in hard-to-reach places, e.g. B. rock slopes. Most stumps are nowadays removed with construction machinery such as excavators , wheel loaders or with a stump grinder . Another problem is estimating the correct amount of explosives. Overestimation can cause violent splinters, so that the restricted area must be increased accordingly. This is not always possible.
