Extraction blast

from Wikipedia, the free encyclopedia

As recovering blast (also Abtragssprengung ) blowing up of rock or soil is referred to, which is used for the extraction of material. Extraction blasting is used to more easily obtain material such as sand or gravel for the construction of traffic routes or for other processing (for example in the cement industry ). An earlier process for this was the so-called Romperit process.
