Analytical determination of granulometric composition of the blasted mining mass by borehole charges of crushing

Keywords: rock massif, limiting radius of the cavity, radii of the zones of intensive crushing, conditional content of natural separateness, volumes of intensive destruction, total destruction of the block, granulometric composition.

The paper describes an analytical method developed by the authors for determination of the granulometric composition of blasted mining mass during blasting of the benches by the borehole charges. The method is based on taking into account of the sizes of the zones of intensive crushing and content of natural separateness in the rock massif. The radii of the zones of intense crushing are calculated on the given physical-mechanical properties of the blasted rocks and physical-chemical characteristics of the used explosives. Value of the coefficient is substantiated that takes into account the proportion of rock massif destruction due to the reflected wave of the explosion puffing effect.

Rock crushing by the quasistatic phase of explosion in the top part of the blasthole charge

Keywords: final length, quasistatic phase, cavity, mass speed, tension, energy, energy of destruction, crushing

Crushing of rocks is carried out mainly by three phases of development of explosion: camouflage, wave and quasistatic. Quasistatic action of explosion is meant as processes which develop in a massif at a stage secondary, after wave expansion of a gas cavity. In article the description of the offered model of a shape of a cavity and a zone of quasistatic action of explosion in the top part of a blasthole charge is given. The received mathematical dependences for determination of volumes and parameters are given in an area of coverage of spherical part of a quasistatic phase of explosion. By the developed technique, with use of the developed computer program, parameters of process and fineness of crushing of rock by a quasistatic phase of explosion, in the top part of a ledge are calculated. Results of demonstration calculation of distribution of energy of destruction and fineness of crushing of rock on conditionally allocated settlement volumes are given.

Crushing of the top layer camouflage, wave and quasistatic phases of explosion

Keywords: final length, camouflage phase, wave phase, quasistatic phase, cavity, energy, energy of destruction, crushing.

Impact of explosion on a massif is process multiphase. In a zone, adjacent to a charge, the camouflage phase of explosion is realized. Beyond its limits as continuation of distribution of a wave of tension, is realized a wave phase of explosion. With a time lag on these zones it is imposed after a wave (quasistatic) phase of explosion. The developed theory of multiphase and multizonal crushing of rocks by blasthole charges of industrial explosive materials of final length is provided in article. With use of the models of development of phases of physical process, the developed mathematical dependences offered by authors for determination of fineness of crushing of rock in the top layer of a career ledge camouflage, wave, quasistatic phases of explosion and their joint action. Settlement results of distribution of density of energy of destruction, and fineness of crushing of rock, on conditionally allocated settlement layers are shown.

Teoretical estimation of microfractured area radius after camouflet explosion

Keywords: camouflet explosion, wave, elastic strain zone, rock extension, microcrack growth, microfractured area

The paper considers stress state in rock elastic deformation area under dynamical effect of blast wave and gives estimation of radius of natural microcrack activation area, i.e. rock prefracture area. Under the condition of spherical symmetry the radius is found from a system of equations including terms for gas pressure in explosion cavity, rock pressure in rock mass, rock fracture strength, characteristic size of rock natural microcracks (defects), as well as Young’s modulus and Poisson coefficient. Quantitative estimation of prefracture area radii is made for several rock types. It is established that size of this area depends mainly on two independent microstructural factors, i.e. rock fracture toughness and rock natural defects. Sizes of rock prefracture area may differ by several-fold depending on these parameters.

For the method of controlling the operation of explosion in difficult conditions

Keywords: explosion, explosive, means of initiation, the structure of the rocks, scale blasting, charge design, concentrated charges.

The article describes a new principle of management by the action of an explosion of large-scale blasting in complex geological conditions, including selective breaking. The essence lies in the development of the cumulative effect, but if the known method is represented by one physical charge, then for the purposes of the explosive destruction of rocks considered the idea of a directional explosion of several simultaneously explode contiguous borehole charges. In practice, a single charge is replaced by a large diameter beam is equal to the total energy of the charges is smaller, the shape of the arrangement which reproduces the effect of a directional explosion quasiedible charge. This opens up new, including principally the nature, opportunities in solving the problem of controlled actions of the explosion. In open studies, for example, is the creation of drilling platforms for simultaneous drilling of closely spaced wells in the beams of different configurations. Underground work - development of new solutions for the design of drilling and blasting, combining large-scale breaking of beam and customary charges, with the aim of significantly increasing the degree of fragmentation of the rock mass.

Support functions of three-dimensional stress state of inhomogeneous rocks

Keywords: initial mechanical model, stress-strain State, rocks, mechanical model, the function of the rocks, the three-dimensional stress state.

The proposed decision analytical tasks define specific indicators of status changes of mechanical process in heterogeneous rocks under the influence of a complex array of stress state on the basis of the newly formulated dependency of physical parameters and indicators to evaluate the change of mechanical environment in conditions of dynamic loads from blasting, operated by the cuts, the State of underground mines. Shown that the mechanical process of redistribution of volumetric stress state is difficult is in the zone of maximum compressive stress and the limit State in the zone. Sound arguments about that change of a volume tension near excavations and, especially in a zone of limit states, is characterized by change of size of the parameter defining a type of a volume tension from +1 in a zone of the untouched massif, to-1 near an excavation, for characteristic types of destructions of the pedigree massif from shift to a separation.

Concerning to the emergence of screening during of crushed granite mining

Keywords: screening, granulometric composition, zones of destruction, logarithmic variance, а wave, pressure

This paper discusses the model of granite massive destruction by the energy of explosion. Some results of reseaches of the granulometric composition distribution of the mechanical destruction product of the exploded mining mass after three crushing stages at the concentrator are shown. It is shown that the blockiness and the granulometric composition of destroyed granite massive are approximated by logarithmic normal distributions with the same values. It allows to characterize the entire set of pieces by a single distribution parameter by average value (for example, the average size of a piece of the exploded mining mass). It is assumed that the amount of output screening depends on the grinding zone size and on the area of high crushing which are estimated for the granite deposits as 12-30 radii of explosive charge.

Determination of the screening amount during the breakstone production in depending of the primary drilling and blasting parameters

Keywords: breakstone, granulometric composition, screening, zones of destruction, specific fuel, net wells, cost of production

This paper discusses the hypothesis of screening emergence during the crushed granite production. The research results show that the screening amount is the function of the primary drilling and blasting parameters such as specific consumption of explosives and some parameters of the well-network. It is shown that the amount of substandard breakstone (less than 5 mm) is equal to the size of overgrinding and high crushing areas. The dependence of the yield screening rates from the primary drilling and blasting parameters and the calculation of the breakstone production cost considering the release of non-conforming fraction are obtained.

North-Eastern Federal University (Yakutsk, Russia)The article focuses on blasting complex massive structures using additional explosive charges in drill holes in the central zone between the main holes inside the periphery of the solid layer, as well as combined charges in the main holes, which rules out the emergence of oversized bits of rock. Requirements are proposed for selecting explosives for main and additional charges based on the physical and mechanical properties of massive rocks which allow one to provide for the required quality of fragmentation. The results are not tied to any method of determining the radius (diameter) of the regulated fragmentation zone which are typically associated with rock fragmentation methods involving blasting. This implies a possibility of using theoretic and empirical correlation for the radii of the regulated fragmentation zone.

Blasting complex rock mass structures criteria equations for parameters of industrial explosives and properties of rocks

Keywords: rock blasting, massives with different degree of solidity, hard rock layers, drill hole charge, additional drill holes, criteria equation, drill hole diameter, charge parameters.

In article theoretical research and justification of parameters of a charge for destruction of the difficult structure massif from the different durability of rocks is conducted. Blasting complex rock mass structures with rocks of varying solidity results in the emergence of intact zones in the hard rock layer. To account for this problem, additional charges placed in the center of the basic cell of drill hole networks are used. This paper proposes a criteria equation for non-dimensional variables that unites the parameters of industrial explosives in the additional drill hole and allows one to model explosive processes based on the similarity and dimension theory.

Experimental determination of the possibility of manufacturing mixtures with high flowability and heating of the components

Keywords: Explosives, ammonium nitrate, mixtures, explosive characteristics, caking ability, waterproof, paraffin, dinitrotoluene, detonating velocity.

The experimental results for the preparation of new types of industrial explosives based on ammonium nitrate by using semi-finished product of trinitrotoluene synthesis and wax-like substances as fuel materials were shown. The basic advantages and disadvantages of the developed mixtures of ammonium nitrate/fuel were found out. The calculation of explosive characteristics of mixtures on the basis of ammonium nitrate was conducted, and some design characteristics of the studied compounds were presented. The experiments on determination of physical and chemical characteristics of the given mixtures were carried out. The method of recycling technical dinitrotoluene by using it for the manufacture of granular mixed explosives based on ammonium nitrate was suggested. An express method for determination of caking in industrial explosives was developed. The results of laboratory tests of these components were provided. The results obtained show that the developed compositions are suitable for practical application in mining industry and do not concede the existing analogues.

About research methods of detonation characteristics of explosives

Keywords: detonation velocity, methods of measuring the velocity of detonation, explosives, isoentropic exponent, detonation pressure, the density of explosives, methods of measurement of the detonation velocity, modern digital equipment Data Trap II.

There are different ways to study of detonation processes. Each of them has some accuracy and appropriate scope. The article provides an overview of known methods for measuring the speed of propagation of the detonation wave and the analysis of the current state of the study of detonation processes. The velocity of detonation of explosives determines the parameters of the damaging effects of explosions in the given environment. Industrial explosives, manufactured in the field of application (emulsion explosives) have a non-constant density of loading. The reason is that the explosive substance of not conventionally explosive components is obtained directly in mechanized loading wells and the margin of error of quality control density lead to a specific range of values. Accordingly, the velocity of detonation of charges from one borehole to another also has a range of values. Therefore, the research methods of the detonation characteristics of explosives deserve particular attention. Especially if you can apply these techniques in a production environment, directly at explosions excavation blocks at the quarries.

The measuring system for determining the detonation velocity of energy-intensive materials

Keywords: measuring system, detonation velocity, energy-intensive materials, electrical contact pin, oscillograph, initiation, detonation wave

The description of MMD-SО1 measuring system for determining the characteristics of impact-detonated waves as well as the procedures of conducting the experiments on determining the detonation velocity of energy-intensive materials by using this system is given in the article. The research on determining the detonation of known and new energy-intensive materials by means of the measuring system and electrical contact pins were carried out. 6ZHB ammonite with the density ρ=1.21 g/cm3 and trinitrotoluol (TNT) with the density ρ=1.57 g/cm3 were used as samples of known energy-intensive materials. Experimental materials having pressed and gelatinous structures with the density 1.59 g/cm3 и 1.49 g/cm3 respectively were used as new energy-intensive materials . It is established that the measuring system permits to measure the detonation velocity to high precision, being founded on the comparison of the experimental values of the detonation velocity of the given energy-intensive materials with reference and calculated one. The relative deviation of experiment results from reference and calculated ones makes up no more than 1%.

On a staggered mesh arrangement of wells for blasting at quarries

Keywords: drilling and blasting operations, scheme of initiation, the grid location of wells, destruction of rocks, diagonal circuit, density of the rock

The application in the production of blasting chess the location of the blast hole. For a long time, the effectiveness of this approach was uncertain. This is primarily due to certain difficulties in the process of drilling. However, a number of works performed in the Institute of mining of the Ministry of ferrous metallurgy of the USSR showed the effectiveness of a staggered arrangement of the wells using the diagonal scheme of initiation of the explosive charges in the excavation blocks at the quarries. In the topic was formulated, the scientific theoretical provisions allowing for the use of the approach to determining the angle of inclination of the diagonal in almost all rocks. Currently this approach has good prospects for development. With the study of the direction of the cracks of rocks within the boundaries of an excavation unit can efficiently use the slope of the diagonal of the initiation of charges, due to the checkerboard layout. The use of conditionally chess grids of wells location in the excavation blocks due to the establishment of rational direction of initiation of charges to increase crushing action of the explosion.

Modelling of the phenomenon of influence boundary modes on intensity of the front of distribution of chain processes in coal mines

Keywords: modeling, concentration profile, chain reactions, border regime, instant point sources, diffusion front, crakes in mine.

In the article develop the concepts about the formation of the active particles front in the diffusion limit of propagation in small volumes (cracks etc.) of coal mines. The results indicate that, if coal dust particles are heated up to 200-300C (even in a cool atmosphere of the mine) due to absorption of radiation present in the mine, the combustion reaction of methane can be initiated in the cracks. By means of modeling the role of cracks surface treatment during the reaction on the front intensity of active particles was investigated. It was found that due to treatment the intensity of reaction front in the center can be increased up to 50%. This is conditioned by the increase of initiation centers on the cross section of the reaction zone volume. It is concluded that cracks and deepening’s filled with a combustible gas + coal + air mixture, can serve as a source of active particles discharge into the mine' volume. This may cause combustion and explosion in the mine.

Keyworlds: adiabatic shear bands, explosion, deformation, penetration of the projectile, plug, shock wave, unloading wave.

Analysis of projectile penetration into the target with account of interference of lateral unloading waves allowed one to install one of the fundamental laws of shock interaction: penetration of an elongated deformed body is an interrupted process and accompanied by repeated loading pulse compression flux appearing as a result of internal projectile velocity braking. The plugging before the projectile moving is a two-step mechanism. The penetration interrupts after the lateral unloading waves overlap the whole area of the contact and zero pressure is established there. The lateral unloading wave focusing induces longitudinal needlelike cracking. The second penetration stage involves internal penetrator movement braking forming a compression pulse flux which recovers the interrupted penetration process. The interference of the unloading waves which sources are side faces of the penetrator and the needlelike crack, creates a cylindrical high tensile stress zone. At velocities close to the ballistic limit the cylindrical spall damage is an adiabatic shear band (strain localized band) responsible for plugging, as in the zone of unloading wave interference the tensile stress does not reach the dynamic material strength and discontinuity does not occur. Increasing the impact velocity over ballistic limit is accompanied by formation of new longitudinal circular cracks breaking down the previously formed plug.
