About large scale ore stripping at open pits

Article preview

One of the possible ways of large-scale rock mass stripping at open pits by two-stage blocks is considered. The proposed method allows 5-6 times to increase the volume of ore stripped in one blast on the block.

On approaches to determining blast efficiency in geotechnology

Article preview

As is known, the external indicators of the development of mineral deposits (geology, requirements for the final technological indicators, etc.) are constantly becoming more complex. At the same time, in the modern mining practice the most important role is played by the processes of destruction as the basis of mining, and the main means at the head of all geotechnologies of solid minerals extraction is the explosive energy. It has a price and its intrinsic controllability.

Second stage of wave-free expansion of the cavity of a concentrated explosive charge

Article preview

In the technical literature, it is widely accepted that crushing of rock during explosion is carried out by stress waves, that only 1-5% of the energy of stress waves is spent on crushing. When exploding an explosive charge in a rock, the nature of energy transfer to the external environment depends on the properties of the explosive, charge density, the geometry of the charge and its position in the massif.
