We propose a device which produces a high density cloud of spray that is consisted mostly of water micro droplets. The cloud automatically occurs when an electromagnetic pulse or/and shock wave from a close explosion matches the device. The ratio of absorbed energy of the dangerous shock wave depends on the density of the cloud and on its spreading speed as well as on the size and the mass of micro droplets. We have developed a mathematical model of physical processes in the Absorber. Numerical simulations show sa...

The use of non-explosive demolition compounds has been extended within recent years to mining of building materials, as well as for the demolition of buildings and concrete structures in urban conditions. This environmentally friendly method has not been used in action for underground mining. The paper presents the outcomes of the research aimed at the elaboration of a new technology for underground mining of hard ores based on the use of demolition method as an alternative to the explosive one. A new compound of ...
