Еspecially stress wave propagation in layered media

Keywords:explosive impact, thin plate, surface wave attenuation, electromagnetic sensors, waveform

The results of researches of surface waves in thin plates under the influence of explosive momentum. It is shown that the high-frequency components of the surface waves attenuate rapidly with distance, which gives the opportunity to suggest a method of partial 3D, which allows you to pay off the high-frequency harmonics in the near area. Model with partial 3D manipulations can be conditionally applied to study the physical phenomena that occur in the firm Wednesday. In particular, the proposed method was used to study stress fields, mass velocities and displacements that occur when charges of air cavities and air gaps.

Accounting for the time spread of detonators in the charge with air gaps

Keywords:well charge, detonator, air gap, combined Geotechnology, open-pit mining, mine workings, seismic safety

For the special case of a well charge divided into the upper (main) and lower (bottom) parts by air or inert interval, the study of their separate detonation with deceleration is carried out taking into account the spread of the detonator response time in these parts. The bottom part of the charge explodes first, and the upper main part – with a certain slowdown. In this case, the deceleration interval is selected taking into account the spread of the detonator response time in both parts of the charge so that the explosion wave of the lower part of the charge, as well as the destroyed rock, limits the seismic action from the upper part to the underlying objects

Theory and practice of drilling and blasting preparation of rock mass to underground block leaching

Keywords:underground mining, ore deposits, complex structure, metal leaching, environmental safety, subsoil protection

Given main scientific and practical results of drilling and blasting preparation of rock mass to the WSP is subject to breaking in the "sandwiched" environment and justify its parameters to ensure the rational use, conservation of natural resources and the environment, combined with geotechnical methods. The methods of generalization, analysis and evaluation of practical experience and scientific achievements in the field of Buro–explosive destruction of solids, continuum mechanics, mathematical statistics, as well as research techniques of wave processes by standard and new methods of leading experts of developed mining countries with the participation of the authors are described. It was found that the explosion on the "clamped" medium occurs in a closed volume, the rock mass is compacted, and the loosening coefficient as the layer is gradually reduced to 1,2-1,18. The compacted rock mass transfers unspent energy to the chamber walls, increasing the seismic effect of explosive vibrations by 1.3-1.5 times. The main problem with the breaking of ore mass in cells with a "clip" and training her to underground block leaching is the adjustment of the mass of blowing up explosives in one slowdown and the explosion in General. Which requires instrumental measurements of the displacement rate from soil surface of protected objects.

Monitoring of natural and antropogenic seismic effects from the results of local explosions at the site of the udachninsky mining and processing plant

Keywords:monitoring, seismic effects, explosions, microearthquakes, shear and normal rigidity

Based on the results of continuous recording of natural and antropogenic seismic effects at the site of the Udachninsky Mining and Processing Plant, a catalog of seismic events was compiled. The records of dependence of high frequency amplitudes on time of explosions on various objects and microearthquakes are given. Seismic monitoring data allowed us to obtain records of seismic signals and evaluate the mechanical characteristics of the selected structure. Based on the change in the amplitudes of the longitudinal and transverse seismic waves from the explosions, the values of the stiffnesses were estimated and the experimental design parameters were given.

Mathematical model of optimal choice technological schemes of treatment works in coal mines

Keywords:technological schemes, treatment works, mathematical models, analysis, synthesis, subsystem, elements

The article shows the methodological basis for the construction and implementation of optimization mathematical models of processes and subsystems of coal mines according to the criteria of adaptation, and gives mathematical justification for their calculation from a single technological point of view. The mechanism of creation of mathematical model of formation of rational variants of technological schemes of clearing works on the global criterion on the basis of the analysis and synthesis of elements of schemes on local criteria is offered.
