Influence of upper zone regulated by crushing out oversize the career the unit

Keywords: granulometric composition, oversized output, phase of the explosion process, category fracturing, crushing rocks, the thickness of the top layer

The article describes the method for calculating the size of pieces of rock in the upper layer of the ledge in the explosion of a borehole charge. The top layer is the main supplier of major factions in the quarries. The study of patterns of crushing rocks in this layer is of great scientific and practical interest. Calculation method takes into account the category of fractured rocks and destructive effect kamuflet, wave and quasi-static phase of the process and a thickness of the upper layer ledge.

The impact of the enlargement products detonation at the time of departure of tamping with the explosion of borehole charges

Keywords: tamping, detonation products, isotherm, adiabata, pressure, process

Describes the parameters of departure stemming from the well when the explosion of the explosive charge. Feature of the work is considering the effect of expansion of the detonation products and a corresponding reduction in time of gas pressure on the tamping when it is accelerated motion. It is shown that a relatively small divergence of the results at constant pressure gases and by reducing this pressure on adiabate apparently due to the fact that the movement of the tamping in the absence of friction is determined by its acceleration in the initial stage.

The account of forces of friction when moving the tamping in the well

Keywords: tamping, the products of detonation, friction, side thrust, adiabata

A study of the process of departure of tamping with the influence of friction forces on the movement of the tamping in the well. The resulting friction between the tamping and the borehole walls is proportional to the lateral thrust of the tamping, due to its compression under the action of inertia forces when accelerating its movement. It is established that one of the effective ways to control the duration of the explosive impulse is the choice of material tamping or create methods of enhancing the coefficient of friction between the tamping and the borehole walls.

Improvement of methods for blasting cuts parameters calculation

Keywords: drilling and blasting, straight cut, parameters of blast holes, review, charge, blast

To ensure better performance of sinking operations and safety of blasting in the mining practice, special attention is drawn to improving the cutting cavity calculation methods. In this paper, the experience in developing the calculation methods for the blasting cuts parameters are generalized and analyzed. Straight and perimeter holes were recognized to be the most effective blasting cuts. The main drawbacks of current methods for calculating blast cuts are shown. The extent of influence was assessed for the importance of defining the breakthrough distance between the charged blast holes and perimeter holes. Based on these studies, the authors suggest the new calculation procedure of the box-type cut corresponding to the mining and geological and mine-engineering features peculiar for sinking operations in laterals and brows. The feature of this method is its direct relation to the destruction areas radii of the rock mass when using extended cylindrical charge of the explosive. The paper contains the developed design parameters of cut holes. The suggested solution allows increasing the efficiency of cavity development, which in turn increases the blast hole efficiency ratio. The paper provides the data on production validation of these calculation methods for straight box-type cut at the Komsomolsky mine, Skalistaya hole where the improved blasting results were achieved on the mentioned parameters.

Seismic effect when for drilling mining operations are used destructor

Keywords: blasting, blast-hole charges, staff BB destructor of seismic wave, seismic effect, TNT equivalent

The paper discusses the issues of conducting blasting mining operations in the limestone, using in boreholes, instead of standard explosive, knock-free composition – Destructor. Accelerograms was carried out by registration of seismic waves in the sinking of limestone in the oblique stroke metro station Dmitrovskaya using Destructor. It is shown that the maximum oscillation velocity of seismic wave from the action of the Destructor is ten times smaller than the amplitude of seismic waves from the standart explosives. According to the maximum oscillation speed of seismic waves was estimated TNT equivalent of a Destructor in the limestone, which turned out to be less than 0,004. This quality of Destructor allows this Destructor is widely used instead of standard explosives, when intense seismic impact on the mountain and facilities are not allowed.
