Estimation of impact of pressure in charger camera on rock pre-fracture

Keywords: rock, camouflage explosion, elastic wave, velocity of detonation, rock stretching, wave pre-failure

To improve prognosis for rock pre-fracture under explosion we studied dynamic stress state of an elastic deformation area of the rock far from the charging cavity. The novel character of the study is that we took into account phase of pressure increasing in the explosion cavity. A relationship was established between maximum tensile stress in elastic wave and velocity of the pressure increase. This relationship demonstrates that elongation of pressure increase phase in the explosion cavity is associated with decrease in magnitude of the peak tensile stress. The conclusion was made that explosives with different velocities of detonation might be used to control explosive pre-fracture of the rock

Analysis of the effectiveness of the explosive destruction of complex arrays of rocks

Keywords: complex array, detonation products, camouflage blast hole charge, pulse pressure, charging parameters

The previously proposed theory of explosive destruction of complex arrays is considering lots of rocks with different strength in isolation from each other. However, after completion of detonation of the explosive charge in the borehole, the volume of the well, zones adjustable crushing in hard and soft rocks that were occupied by the detonation products of the explosive charge, linked and form a single net between them, and therefore it is possible to flow gases. When you take this into account, the radii of the controlled crushing of these rocks are determined by the dynamics of gas movement in the specified volume.

The substantiation requirements of the specific conductivity of the emulsion in the production of emulsion explosives sensitized by foam polystyrene granules

Keywords: emulsion explosives, emulsion, dielectrophoretically strength, specific conductivity of the emulsion

This paper is devoted to the prevention of cases of destruction of the emulsion granules sensitized polystyrene, dielectrophoretically forces, which may arise in the electrification of polystyrene in the process of manufacture of emulsion explosives and charging works. In this paper we obtain a criterion to evaluate the danger of destruction of the emulsion under the action of forces dielectrophoretically. The performed studies allow to evaluate the influence of structure and electrical conductivity of emulsions, in the composition of emulsion explosives, the possibility of its destruction under the influence of an electric field generated by the charged pellets of polystyrene, which is in the considered emulsion. This enables to prevent malfunction of borehole charges of emulsion explosives sensitized by granules of polystyrene, which increases the level of safety of blasting operations with the use of such EE.

Evaluation of detonation characteristics of emulsion explosives obtained by the method of chemical sensitization with the additional introduction in the composition of the fibers of chrysotile asbestos

Keywords: paramit1A, chrysotile-asbestos, emulsion explosive, velocity of detonation, solid porous materials, gas-generating additive, chemical gasification, microsphere

Experience of application of emulsion explosives (emulsion explosives) both in Russia and abroad, shows optimal results of the ratios of the cost of explosives (EXPLOSIVES) and quality of beats rock. In addition, there is the possibility of creating special formulations of emulsion explosives by the introduction of various additives that can be applied in varying geological conditions at production sites, which gives them a significant advantage over other types of EXPLOSIVES. It is established that the main characteristics of emulsion explosives can be determined, both in field and in production environments. One of the most important detonation characteristics of emulsion explosives is the detonation velocity (DM). Measurements of DM and EE were heldrheostatic method of using the device DATATRAP II DATA/VOD Recorder ("MREL Group of Companies Limited" Canada). On the basis of the conducted experiments, developed methods of measuring actual DM sensitized emulsion paramita-1A, to determine the detonation characteristics of emulsion explosives obtained by chemical gasification with the use of microspheres. The experimental results allow us to determine other characteristics necessary to ensure rational parameters of drilling and blasting.

Assessment of contour rock mass disturbance degree in mine excavation at different perimeter blasting methods under high rock pressure

Keywords: perimeter blasting, outside-contour destructions, explosives, seismic effect of blast

The paper gives the results of a testing assessment of contour rock mass disturbance degree during driving large-section mine excavations (up to 17-24 m2) and depth of blast-holes up to 4.5 m when performing the further outlining with explosive columns of perimeter blasting, cartridges containing ammonite 6ZhV and emulsion explosives. It is revealed that all the blasting methods observed result in opening or generating new fissures on considerable depth from the excavation perimeter and their maximum generation is registered in splittings adjacent to a face broken-up. This is connected as with blasting impact of blast-hole charge groups, so with redistribution of stresses near to a working face as an excavation progresses.

Practic method of taking into account the dominant frequency of vibrations when calculation of safe seismic distances in blasts at the quarries

Keywords: blasting operations, seismic safety, regression analysis, the dominant frequency of the oscillations, open pit mining, frequency-dependent seismic hazard criteria

The method for detecting seismic safety distances for blasting works at mining enterprises, taking into account the magnitude of the dominant frequency of oscillations of the earth's surface. The method is based on regression analysis of experimental data, is characterized by the usual structure and simplicity. As a criterion for seismic hazard is used the safety factor, representing the ratio of the peak velocity fluctuations to its maximum permissible value adopted according to the normative documents, taking into account the dominant frequency of oscillation. Instead of the peak rate fluctuations can use other parameters of the oscillations, for example, the maximum displacement of the earth's surface. Also allowed the use of mixed criteria seismic hazard. The method is based on the analysis of experimental data and for this reason fully takes into account both features of blasting on the specific mining company and geological and hydrological conditions on the propagation of seismic waves. An example of using the proposed method at one of the quarries of building materials in the city of Novosibirsk when using different technologies for the initiation of charges.
