Keywords: geomechanics, destruction, concept, rocks, mathematical models, computer simulation, synergism, geodynamic phenomena, explosive blasting, safety

A new methodology for solving new and adjusting known issues in the development of mineral deposits in difficult geohazard conditions is considered, characterized by the formulation of research at the intersection of sciences such as ‘Geomechanics’, ‘Mathematics and Mechanics’, ‘Mechanics of Deformable Solids', and ‘Destruction of Rocks’. With this interaction with mining science, this will allow the use of analogs of theoretical and experimental nature and appropriate tools, in particular, the development of mathematical models and computer technologies for solving specific problems of mining production in order to identify new effects.

Graphoanalytical method of determining the intensity of a preliminary destruction of the surrounding area blast holes

Keywords: explosive destruction of rocks, fracture, stress wave, the intensity of the weakening of the rock mass, maximum deformation

Possibility of definition of rational parameters of explosive destruction of rocks on the basis of the account of zones of preliminary destruction is considered. The process of brittle destruction of rocks by explosion is characterized by one type of destruction – separation under the action of tensile stresses from the action of the compression wave in the dilution phase. This leads to the formation of crack systems that cut through the rock mass. It is proposed to determine the intensity of the attenuation of the array in the area of each exploding well by differential calculation of the magnitude of the well charges for different zones of weakening of the array occurring during the development of the explosion. A preliminary graphical analysis of the planned scheme of explosion on the drilled and the next blocks determines the parameters of stress waves passing through the vicinity of specific wells covered by the zones of preliminary destruction from the explosions of previous borehole charges: the number of waves and the distance to the explosion of previous charges. Studies have shown that the total pre-deformation of the vicinity of the wells throughout the block before the explosion of almost every well exceeds the limit value of deformation, which leads to over-grinding of the material and over-consumption of explosives. It is proposed to determine the value of the charge of explosives for individual wells in accordance with the preliminary destruction of their surroundings from the explosions of previous wells.

Evaluation of the efficiency of rock crushing charges with air gaps

Keywords: well charge, air gap, diameter of charge and well, charge parameters, adiabatic expansion, fine crushing

The paper gives an overview of the use of air gaps for the dispersion of charges on coal mining enterprises. An analytical analysis of the pressure reduction of the explosive detonation products during the expansion into the air gap formed by the charge dispersion is carried out. Based on the analytical studies, it was shown that the application of the air gaps, significantly reduces the area of fine crushing and, accordingly, dust formation, reduced wasteful expenditure of energy explosion.

Researches of the retaining ability of granular ammonium nitrate

Keywords: explosive, ammonium nitrate, granulated, porous, non-porous emulsion hydrocarbon/water, retention capacity, wetting, bulk density

The article presents experimental results on defining retention capacity of ammonium nitrate (AN) with different initial granule porosity, related to hydrocarbon emulsion in AN water solution and bulk density of the resulting system The mass ratio of water phase in emulsion varied from 10 to 30%. Hydrocarbon phase was represented by the mixture of waste engine oil and diesel fuel, taken in 1/1 mass ratio. The maximal quantity of immobilized fluid phase, primary dependents on the emulsion water content, secondary on the AN concentration in the emulsion water phase, tertiary on the initial AN granule porosity. At the AN concentration of 20% – the maximal retention capacity was: 14-18% for porous, and 8-9% for non-porous; at AN concentration of 50%: 43-47% for porous, and 9-10% for non-porous. The introduction of fine-dispersed сarbon black does not lead to any significant change of the results. The system bulk density varied from 810±20 to 1250±30 kg/m3 depending on AN applied and emulsion composition.

Promising energy-saturated materials are proposed, the selection of components for which is carried out on the basis of design studies, taking into account the requirements for energy-saturated materials used in well conditions. Theoretically, the expediency of the use as an oxidizing agent of potassium rate, and as the combustible components hexachloroethane, hexachlorbenzol or polyvinylchloride with the aim of obtaining in the combustion process of hydrochloric acid as one of the components of combustion products. The dependences of the specific gas, the volumetric output of the heat of combustion and the release of hydrochloric acid during combustion of two-component mixtures on the basis of the oxidizer is potassium rate and chloropropoxy combustible polyvinyl chloride, hexachloroethane and hexachlorobenzene from the content of the oxidizing agent. The most promising composition based on potassium chlorate and polyvinyl chloride, which has the highest values of specific gas formation (1400 l/l with KClO4 content in the range of 55-60 %) and specific heat (4594 j/l with the same content of KClO4) was revealed.

Impact of mass explosions in the underground development of iron deposits for the building and population of the city of Gubkin

Keywords: safety of blasting operations, seismic vibrations, maximal speed of soil vibrations, isoseism of mass explosions, impact of seismic vibrations on people

Seismic explosive waves were recorded in the city of Gubkin during the explosion of iron ore in the Gubkin mine of the KMAruda Combine. The dependence of the maximum velocity of oscillations in the seismic blast wave on the hypocenter distance (up to the explosive mass in the deceleration step) is obtained. Data were obtained on the intensity of the seismic action of mass explosions for the construction of the city. Isoseismes of mass explosions are calculated. Taking into account the requirements of the Sanitary Rules and Norms and Sanitary Norms and taking into account the duration of seismic fluctuations, the value of permissible and maximum permissible speed of seismic vibrations for the city population was estimated. The radii of zones of comfortable and uncomfortable habitation of the population are calculated. Registered air waves in mine explosions. Their impact on the city's population is analyzed
