ABSTRACT

The paper assesses the effectiveness of shock-wave technology cutting for rocks, based on irregular modes of shockwaves interference. That modes occurs when angle in the waves collision greater then critical angle. Shock waves forms in the material upon synchronous detonation of bilinear charges, that designed in the BSTU “VOENMEH”. A theoretical and experimental comparison of materials cutting technologies using a shock-wave and a shaped charge is done. The usage of cumulative cutting in emergency rescue operations is limited by the presence of a hazardous effect on objects behind a barrier. Unlike the shaped charge, the shock-wave cutting destruct materials without mass transfer, and does not damage objects behind the barrier. A reduced in 2…5 times consumption of explosives and higher efficiency of the shock-wave cutting technology is experimentally shown. As the result of significant reduction in consumption of explosives reduces lead times, transportation costs and environmental damage. It follows that the shock-wave cutting technology can be successfully used in mining and emergency rescue operations.
