Influence of structural inhomogeneity on the character of deformation and failure of rocks at the submicronic level

Keywords:rocks, destruction, deformation, stresses, emission of submicron particles

On the basis of theoretical and experimental studies of the processes of deformation and destruction of rocks at the submicron level, a classification of inhomogeneities for monomineral and polymineral rocks has been developed, which has a significant effect on both the intensity of the emission of submicron particles and its granulometric composition. It was found that for polymineral rocks, in contrast to monomineral rocks, the emission of submicron particles can quantitatively differ by several times, and the dependence remains qualitatively unchanged and has exponential growth in all size ranges in the range from 0.3 to 5.0 μm. The cylindrical hole in the samples is an artificial inhomogeneity and serves as a stress concentrator during uniaxial compression of geomaterials. For this purpose, formulas are considered for calculating stresses on inhomogeneities and sizes of inhomogeneities taking into account the rheological features of geomaterials. Based on the analysis of experimental data indicating a wide scatter of quantitative indicators for various types of geomaterials, along with the known strength properties, it is proposed to single out a new property characterizing the process of material disintegration at the submicron level under mechanical loading.

Investigation of the dynamic working of long charges by composition models coupling with computer simulation by the smoothed

Keywords:explosive, elongated charge, fragmentation, physical experiments, computer simulation, SPH (Smoothed Particle Hydrodynamics method)

The application of a combined approach to investigate the effect of an explosion is considered. The proposed complex research technique allows for a comprehensive and most informative assessment of the effectiveness of various explosion modes, studying the nature and kinetics of deformation development, the formation of loosening zones, the localization of which predetermines the fragmentation and formation of model fragments. The materials of the investigation of the influence of the density and diameter of the crushing and sparing action on the yield of various fractions are presented. The nature of the dependences of the fragmentation speciments in different zones of the explosion was established. It is shown that the nature of the dependence of fragmentation on the density of an explosive fundamentally different for explosives containing blasting action and ammonium nitrate industrial explosives with different densities. The proposed research methodology makes it possible to obtain the dependencies necessary for the formation of digital models of optimization and adjustment of the parameters of drilling and blasting operations, charge designs and detonation systems based on them to reduce the yield of fines and achieve optimal crushing parameters.
The work was carried out within the framework of the budgetary theme of IPKON RAS.

Estimation of the influence of EVV parameters on the size of rock fracture zones under conditions of different drilling diameters

Keywords:the velocity of detonation, detonation products, deep-hole charge, the diameter of the bore, the charge parameters

A comparative analysis of the impact of the detonation rate of emulsion explosives on the size of the zones of explosive destruction of rocks based on the change in the diameter of the well and the explosive characteristics of the EVV charge is carried out. It is shown that with an increase in the detonation rate, both the zone of fine crushing and the zone of controlled crushing increase, and for the latter there is a significant increase (several times). It is assumed that the coupling of adiabatic de-tonation products occurs at the border of zones of fine crushing and radial cracks. The pressure drop in the zone of fine crushing has a sharper character due to the higher value of the adiabatic index and the complete release of pores. In the zone of radial cracks, the pressure changes more slowly, which causes a large radius of this zone. The importance of controlling the explosion parameters based on the correct selection of the charge diameter and its explosive characteristics in the near and far zones from the final contour of the quarry in deep quarries with a high production capacity of rock mass excavation is noted.

Methods for assessing the seismic impact of an explosion at quarries

Keywords:mountain range, seismics, strength, drilling and blasting operations, rocks

A method for estimating the destructive seismic effect of simultaneous explosions at the KUMTOR mining enterprise in the Republic of Kyrgyzstan is proposed. The area of seismic interaction between exploding blocks located at a distance of 600 meters from each other is estimated. The scheme of short-delayed detonation, the explosive substance igdanit, was used. The design of the explosive network was carried out using the SHOTPlus program using the non-electric initiation system Exel MS (bottom) and Exel HTD surface company ORIKA. The results are obtained for rocks that are in a frozen state.

Study of the chemical compatibility of emulsion explosives with rocks of Кhibiny massif and assessment of its consequences

Keywords:emulsion explosives, chemical compatibility, carbonaties, williomite, safety, environmental pollution

The paper presents studies of the chemical compatibility of ammonium nitrate, as the main component of emulsion explosives, with the rocks of the Nyorkpakhsky deposit of apatite-nepheline ores in the Khibiny massif. The mineral composition of the ores and the host rocks of the deposit was estimated and the negative effect of carbonate and fluorine-containing rock-forming minerals on the stability of ammonium nitrate was established, which can lead to foaming of charges in the wells after charging, a decrease in charge density and, as a result, a decrease in volumetric energy and detonation characteristics of the charge. Thermochemical calculations showed that the reaction between the components of explosives and rock minerals is endothermic – they absorb heat, therefore, the mixture does not heat up when the components interact. The considered interactions cannot lead to emergency situations of self-heating and decomposition of well charges of emulsion explosives. The explosive mixture and products of incomplete oxidation in the environment pollutes it. The increase in the content of «pollutants» is due either to the partial dissolution of ammonium nitrate or to the release of nitrogen oxides resulting from a decrease in the detonation ability of the charge.

High-ranking technology of the works with dragline

Keywords:high ledges, drilling, angle of slope of the board, width of collapse, granulometric composition, front of dissection works

High-level mining technology is being considered, which ensures a reduction in the current volume of dissection work by increasing the angle of the escarpment of the working side. It is shown that compared to the existing technology, the volume of dissection work during the period of restructuring of the working board is reduced by half, and the real technological scheme of the opening zone differs from the scheme considered by the breakdown of the total height of the open on separate ledges and the cyclical nature of the development of open ledges by separate openings. In the case of incision conditions, the appropriate height of the open ledges is between 25 and 35 m, which provides the possibility of bringing the angle of the escarpment of the working board to 25-270, against their existing traditional values of 12-150, with a corresponding decrease in the current volume of dissection work. The results of studies of the explosion of high ledges are considered as one of the elements of improving the technology of explosive preparation of the mountain range for excavation in the development of mineral deposits by deep quarries.

Investigation of schemes and parameters of breaking at the floor-and-chamber mining system of copper pyrite Urals deposits

Keywords:copper-pyrite deposits, oversized yield, unregulated crushing zone, ore drawing, blast hole ring charges, blast hole bunch, breaking schemes, counter blasting

In the underground mining of copper pyrite deposits in the Urals by a floor-and-chamber mining system with gob filling with hardening tab, the issue of increasing the efficiency of self-propelled loading and delivery equipment at ore output is rather acute. The most negative factor in this case is a significant (up to 12-19%) yield of oversized fractions during the production of explosive ore breaking. In addition to the time spent on the process of filling the bucket of the loading and delivery machine and further transporting the oversized material to the secondary crushing chamber, tire wear is also significant and the cost of fuels and lubricants per ton of ore mined is increasing. In this paper, the main ways to reduce the oversize yield when mining primary and secondary chambers based on various schemes of explosive breaking are proposed and considered. As a result of the studies, the main technical and economic indicators of the considered schemes, the areas of their effective application were established, and the flight parameters between the outcrop planes during the oncoming breakdown of the blast hole ring charges were justified.

Justification of the parameters of drilling and blasting operations in the formation of the bottom of operating units in energy-disturbed mining masses

Keywords:rock massifs, blasthole parameters, bottoms, blocks, undercutting, geological environment, environmental safety, efficiency

The article describes methods of generalization, analysis and evaluation of practical experience and scientific achievements in the field of drilling and blasting destruction of solid media, mechanics of continuous media, mathematical statistics, as well as research methods of wave processes. The technique of substantiating the blasthole parameters during the formation of trench undercutting of reserves of the production block with sucker-rod holes or wells with a diameter of 50-105 mm drilled from undercut workings located at the level of the haulage horizon or higher by 3-5 m. It is shown that the use of geochemical technologies for leaching metals in devices installed in underground workings makes it necessary to improve the design of the block bottom. The preparation of the receiving horizon should be carried out in the form of a flat bottom, silted with clay solution at an angle of up to 5-6 degrees towards the collection of the productive solution. Drill observation wells into the ore body contour and the horizon for catching productive solutions, as well as flushing with process water through the existing irrigation system. This ensures a reduction in the ingress of harmful pollutants into the geological environment.

Keywords:rock massifs, technologies and technical means, mine workings, drilling and blasting, prismatic cuttings, safety, efficiency

The article presents the main scientific and practical results of improving technologies and technical means for drilling and blasting horizontal mine workings in rock massifs obtained on the basis of the results of studying the changing geomechanical, mining and hydrogeological conditions of the field. mathematical modeling of BWR parameters and new designs of prismatic cuttings with an uncharged well. This will ensure a high-quality development with the care of the face for a cycle of at least 3.3-3.5 m and increase the safety of operation during its lifetime. Methods of generalization, analysis and evaluation of practical experience and scientific achievements in the field of drilling and blasting of solid media, continuum mechanics, mathematical statistics, as well as research techniques of wave processes using standard and new methods of leading specialists of developed mining countries with the participation of the authors are described. The prismatic cuttings and parameters of drilling and blasting operations for the sinking of mine workings and the depth of holes in the faces up to 3.5 m are justified. It is established that in addition to productive self-propelled equipment, there is a need for new designs of prismatic cuttings, with a high-quality (clean) cut cavity up to 0.95-1.0. Seven variants of new designs of prismatic cuttings with uncharged boreholes with diameters of 105, 85 and 74 mm are proposed. Prismatic cuttings with compensating volume (wells of various diameters from 65 to 105 mm) are proved and developed.
