Shafts - Cavosa



The execution of mining and civil works implies in a large part of the cases the realization of shaft. These works can be done with different methods, such as drilling and blasting, mechanical digging with a backhoe, using Raise Boring and later widening or by using VSM (vertical Shaft Shinking Machine) specialized in the execution of extrusion shafts, in which  Cavosa is a pioneer in the world.
Cavosa also has extensive experience in the development of customized machines for the execution of non-vertical shafts where conventional machinery is not applicable, as in the case of the EPYSTEI in which Cavosa developed and operated two specific machines for the execution of a shaft 700 meters deep, 45 degrees inclined and 7 meters in diameter.
