BOULDER BUSTER, sistema di demolizione controllata.

A safe wrecker: advantages:

• BOULDER-BUSTER is manageable and safe in its use
• No risk of damage to nearby structures and equipment
• The shockwave of the Boulder Buster is guided into a hole filled with water
• Boulder Buster generates much-reduced noise and very few vibrations
• No launch of fragments
• Boulder Buster can be transported by airmail as security munition.

Wrecker Use

BOULDER-BUSTER is a portable tool of demolition for quarries, mines, construction sites and excavation and can be used for numerous types of jobs such as:

• trench digging;
• demolition of rocks and reinforced concrete;
• underwater excavation;
• sectioning and resquaring of banks and blocks;
• demolition of "trovanti" and erratic isolated rocks;
• excavations of masses and rocks;
• agriculture and forests;
• civil defence;

Functioning basics

BOULDER-BUSTER is a device for controlled demolition that utilizes propellant technology. The wave of shock and pressure is generated in the device by a cartridge filled with a mixture of propellants. The shockwave that derives from it is conveyed by means of an exit barrel on a column of non-compressible fluid (water or gel) (hole in the rock filled with water).

The positive result of this system resides in the propellant technology.
The characteristics of the propellant and the cartridge design allow the rapid development of a pressure wave (transmission in very short time). This impulse of pressure transmitted on the column of fluid acts on the micro-fractures produced during the drilling.
The static pressure developed by the propellant produces another force that translates itself into the fracturing of the rock.
