In clause some positions of algorithm of complexes of computer programs «Disorder – cascade 1» and «Disorder – cascade 2» are stated. Examples of calculation of disorders are resulted and described. Graphic representations of disorders are displayed the monitor and printed.
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.
The physical model of the quasi-static phase of the explosion and analytical dependences allowing to calculate the main parameters of this phase are stated.
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.
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.
