The destruction and crushing of rocks in open cast mine

Keywords: destruction of rocks, process crushing rock, explosion, strength, energy supply of technological crushing

The article presents two different concepts (process): destruction of rocks by explosion, and technological fragmentation of rocks by explosion. The destruction of rocks of any violation of their integrity, including the explosion shall be provided if either a necessary condition for the stress in the rock is equal to or above the limit of its strength.
Technological rock crushing explosion, according to the authors, is a higher and more demanding type of destruction. In this case, should be performed two mandatory conditions: stress in the rock should be above the limit of its strength, and the process of crushing rocks to a predetermined size must be provided with energy.
The article argues that the incident stress waves in the quarry are not the main means of transmission of the explosion energy to the rock mass, and is not the main means of energy distribution in the destroyed array.The article describes a computer-aided design methodology for determining the various parameters of the incident voltage wave. The description is accompanied by a graphical and numerical demonstration of the calculations of the selected option.

Empirical studies of the formation of the drain funnel and the phenomena occurring during the explosion of clay under water

Keywords: zone of destruction, explosion, emission, water, clay, depth, charge

At present, theoretical basis to calculating the parameters of explosive areas in various types of underwater rocks for deep dredging for building water works has not been clarified. According to the researches by Russian and other scientists, when underwater rock explosion, it will have two effects: The first effect is increase in the mechanical effect of explosion, because water prevents the rapid loss of explosive gas from being into the air; The second effect is the reduction of the mechanical effect of explosion and destruction, because water prevents the soil particles from moving towards the free surface. The combined effect of the two effects depends on the specific explosive conditions. The level of destruction, the formation of the bursting funnel and the subterranean explosion of the concentrated charge in the rock depends on the depth of water and the depth of the charge in the rock. Using the theory of uniformity and doing on experimental model on a laboratory model help to studying of the formation of a bursting funnel, an subterranean explosion effect and establishing and analysing the effect of water depth and depth of charge on the parameters of the bursting funnel and the compression zone when concentrated charge exploded in underwater clay.

Control of the pressure pulse of detonation products during the explosion of borehole charges at the quarries

The stress field excited in the rock mass as a result of explosion of well charges of explosives and responsible for destruction of the massif is mainly determined by the pressure pulse of detonation products. The paper deals with the processes of forming the pressure pulse and the possibility of controlling the pulse parameters, both in the presence of clogging and in its absence. The formation of a full pressure pulse can be divided into stages defined by different physical processes, including detonation of explosives, expansion of detonation products and their outflow from the well. Managing these processes allows you to get the momentum with the required parameters.

The calculated method of determining the dosage of mixed explosives

Keywords: components of the mixture, explosive, zero oxygen balance, charge energy, preparation of the mixture, technical and economic efficiency

One of the main technological processes of extraction of solid minerals is the Deposit and crushing of rocks by group explosion of dispersed charges of industrial explosives. High-quality crushing of rocks by explosion provides efficiency of performance of all subsequent technological operations of mining production and to a large extent depends on the applied explosive.
The impact of the explosion on the rock mass is the result of the explosive transformation of the chemical process of interaction between the oxidizer and the combustible components of the mixed explosives. The efficiency of the explosion energy spent on crushing rocks depends on the completeness of the interaction of the components of mixed explosives. One of the criteria for evaluation of which is the zerooxygen balance indicating the completeness of oxygen oxidation of the combustible component in full.
The article describes the proposed by the authors of the engineering method of calculating the percentage of doses of components in the mixture of the simplest explosives, designed to calculate the oxygen balance of the mixture used and the choice of the ratio of doses of new components. Developed analytical dependences of definition of doses, providing a zerooxygen balance in the explosion of an industrial explosive mixtures. The developed computer programs for determination of rational mix of components are presented. It is shown that at different ratios of doses of the same components, the zerooxygen balance of the mixture can be ensured during the explosion.
On the basis of the obtained results calculations of doses of mixed explosives for specific conditions of blasting, having zero oxygen balance and including the accompanying components of technological processes of extraction of coal for increase of efficiency of drilling and blasting operations are carried out.

Evaluate the magnitude of the maximum heat release in the detonation wave front in hexogen

Keywords: detonation, explosion products, equation of state, co-storage laws, thermal effect of reaction

On the basis of experimental data on the values of the initial density of matter, linear and mass velocity at the front of a plane detonation wave in a condensed matter, a semi-empirical method is proposed to estimate the parameters of the state equation of the explosion products and the maximum heat dissipation at the Chapman point-the arc of the detonating charge. Cold (elastic) component of the pressure in the equation of state, mie-Gunasena is specified in an exponential form, the grüneisen coefficient is-nanim ratio increased in an exponential law. Using conservation laws at the wave front and conditions of touch shows that Hugoniot adiabatic straight Michelson allows to reduce the parametric problem to the system of algebraic equations whose solution, given an adequate selection rules gives a single value for the indicators of the equation of state and maximum heat dissipation in front of the gas detona tion-tional waves.

The seismic effect of mass explosions in the combined refinement of deep quarries

Keywords: Mass explosion, parameters of explosive charge, seismic action of explosion, combined refinement of deep quarries, explosive blocks, coefficient, which takes into account the change in the velocity of displacement from explosions on different horizons, protected object.

Based on the generalization and analysis of instrumental observations of mass explosions conducted over a long period of time in various blocks and horizons of the «Udachny» quarry, the influence of the depth of the location of the blasted block on the intensity of seismic waves was investigated. To calculate the intensity of seismic oscillations, it is necessary to introduce a correction factor that takes into account the change in the displacement velocity due to a decrease in the horizon of the location of the blast block.
