A sector which is well-known to Apian is that of the demolition of rocks or parts of rocks carried out by means of mines and explosives.
This is a controlled demolition technique with explosives, capable of deflagrating natural stone, as an alternative to percussion demolition (noisier and with more vibrations).

The cooperative operates with non-detonating explosive charges, chemical compounds enclosed in a cartridge that reacts quickly when triggered. These charges are placed into strategic holes which are first made in the rocks.
A remote electronic detonator is used to ignite the charges, producing a considerable volume of non-hazardous gases (mainly nitrogen and carbon dioxide). The deflagration produces material that is removed with an excavator.

Blasting with explosive charges is very much in demand for earthworks in the presence of rocks, and the regulations require that they are carried out by authorized personnel with a blasting license, which Apian performs.
