The result of the expansion of the explosive cavity on stress state of the firm environment

Keywords: charge, pressure, deformation, cavity, border, solid environment

The answer to the Lama about the stress state of a solid medium under the influence of gases on spherical and cylindrical cavities are obtained for a constant pressure in the cavity. Due to the displacement of the boundaries (walls) of the cavity and increase its volume, the equilibrium pressure is much lower. In the present work to estimate the impact of this displacement and a corresponding reduction in gas pressure on the magnitude of strains in the environment.

Evaluation of the efficiency of energy use in crushing of rocks

Keywords: blast, rock, shock, energy, blasting works, crushing of rocks, explosivity of rocks, extent of crushing.

In article the analysis of methods of calculation of the project specific consumption of explosives is made for blasting in the mining industry. It is offered to define explosivity of the massif of rocks in laboratory on samples of rocks based on the study of structural features of the massif and the scale factor. For this purpose the method of estimating the specific energy expended in the crushing of rocks during impact is developed.
For limestones (f=8) dependence of extent of crushing on specific energy consumption is established and its optimum size providing the maximum utilization rate of energy on crushing is determined. It is shown that if the energy is excessive for a particular breed, the efficiency of crushing is reduced significantly and increase the expenses of energy to useless forms of mechanical work.
The conclusion is drawn that for each rock there is an optimum specific energy consumption providing the maximum utilization rate of energy on crushing. The formula for determination of a reference specific consumption of explosives depending on optimum energy consumption is given.

Peculiarities of mongolia climatic conditions influence to the ammonium nitrate explosives usage

Keywords: ammonium nitrate, a granule, explosives, the critical diameter, absorbing ability, a detonation

Formation and current state of mining industry of Mongolia are in close interrelation with history of development of the country, features of a geographical arrangement, climate, and also an equipment level of development in world practice. Mongolia is located in a middle part of the Asian continent on considerable removal from the seas. Average height of an arrangement of the territory of the country concerning level of the ocean makes more than 1000 m. The climate of Mongolia is sharply continental with essential fluctuations of temperature on seasons of year
Durability of crystals and granules of the ammonium nitrate (AN) depends on a way of their receiving at production and numbers of modification transformations to which they can be subjected in the course of product storage. At repeated modification transformations, in particular, upon transition through a temperature point 32,2оС that is possible in real conditions of Mongolia and are characterized by big change of volume of crystals, granules the ammonium nitrate crack. With cracking of granules their absorbing ability in relation to oil products increases, but durability decreases.
At long storage the ammonium nitrate occurs more essential change of a caking, integrity of granules, compatibility with fuel, flowability, etc. At destruction of granules the ammonium nitrate as a result of long storage the increase in holding ability the ammonium nitratein relation to DT to level, sufficient for mixes ASDT is possible, however thus there is a sharp deterioration of operational properties, in particular, flowability. Thus change the ammonium nitrate, being stored, as a rule, in compact stacks, not evenly and not unambiguously on the stack volume that leads to fluctuations of properties of made mixes ASDT uncertain and not giving in to regulation.

The influence of blasting and various types of explosives on the spontaneous combustion of coal mass

Keywords: coal, ammonium nitrate, a granule, explosives, explosibility, flowability, the inflammability absorbing ability, a detonation

In actual practice conducting explosive works the structure of products of explosion becomes various and strongly differs from ideal conditions of explosion. Detonation products chemically more active, in comparison with air oxygen, can enter interaction with breed, in particular, with the coal, being in the activated state, with increase in probability of ignition of coal. To similar result leads also existence as a part of products of explosion of products not full oxidation of combustible additives or trinitrotoluene which as possess the increased chemical activity.
Results of supervision and researches during various periods of working off of coal fields of Mongolia, show that the most active place for emergence of seats of fire – the blown-up masses in blocks of a coal ledge with BVR application. In actual practice it is shown that when loosening breeds by explosion reduction of time of the incubatory period of coal masses before ignition, in comparison with that is observed, when developing a coalfield without use of drilling-and-blasting works.
Ignitions and fires on objects of production and processing of coal lead to essential increase of danger of mining operations and negative impact on environment. Tendency of coal to self-ignition depends on size and activity of his adsorbing surface which is caused by primary factors of genesis: composition of plant material, initial conditions of accumulation and decomposition of maternal substance and character of a metamorphism.
Transition on coal mines of Mongolia on use of the explosives granulated the grubodispersnykh has led to creation to the system debalanced on oxygen balance and allocation at explosion of a large amount of oxides of nitrogen. Broad use of ASDT mixes in 2005-2015, has led to mass cases of self-ignition of coal and technogenic fires with the increased danger of working off of coal fields.
The researches conducted by authors, have allowed to create for conditions of Mongolia special manufacturing techniques and applications ammoniac селитренных VV which have the balanced structure and at explosion allocate the minimum quantity of the poisonous products causing accelerated self-ignition of coal
Application of the developed manufacturing techniques of mixes ASDT practically excludes self-ignition of coals after explosion that significantly increases efficiency and safety of coal mining on cuts of Mongolia.

Method of concealed informative marking of industrial explosives

Keywords: industrial explosives, informative labeling, secretive chemical marking, the marker substance, IDs, spectrophotometry, informative block

A review is given of the known methods of concealed marking of explosives. A new method is described for concealed informative marking of industrial explosives by adding special agents (markers, which can be detected by special analysis methods in the explosive itself or its residues at the blasting site). Information content of marking is achieved by means of information encoding with the use of combinatory codes, which is determined by the combination of marking agents. The concealed nature of marking is maintained by using the marking agents in super low amounts detectable only by means of special physical-chemical analysis methods. The study contains description of spectrophotometric characteristics of some marking agents and threshold concentrations for their identification by spectrophotometer PE-5400UF. The results are given of reading of the marking introduced into a granulated water-emulsion explosive by the proposed method. A methodology is given for identification of marking agents in samples of marked explosives by spectrophotometric method. It was shown that besides the concealed nature, the proposed method of marking of explosives has manifold opportunities for encryption of the data contained in the marking. At that, it is possible to simultaneously implement numerous known methods for encoding all the textual and digital information that must be specified in the marking.

The authors, on the example of polymetallic deposit Maykain propose to use mining methods with backfill. However, such methods often have a problem with dilution of ore with the backfill material during blasting processes that has a negative effect on processing. Therefore, in this article, the method of ore breaking on contact with the backfill is also reviewed. Furthermore, since the strength of artificial backfill mass may vary depending on the mining sequence breaking parameters must also be different. Accordingly, to improve the quality of breaking and reduce the dilution of ore uncharged portion of the blast holesof the ring in their bottom part and in the collar should be set taking into account the length of the discharge zone

In the article the issues of preparation and holding of the explosion for the collapse of reinforced concrete monolithic 9-storey building. The length of the building – 190,4 m, a width of 20.4 m and height is 33.9 m. In the Central part of the building located the block of elevators and stairs with a length of 27.4 m and a width of 20.4 m, which was to be saved. The saved block has previously been separated from the collapsing parts of the building. To reduce the width of collapse of the collapsing structures of the building scheme was used short-delay blasting with the formation of two cuts on the 3rd (main incision) and the 1st floors of the building. To ensure the direction of fall of the collapsing structures of the building first row of columns on the direction of the rolls building was blasted to all floors, the second and third rows of longitudinal columns and reinforced concrete diaphragms of hardness – only 1-m, 3-m and 4-m or 5-m floors. The joints of columns and beams, and transverse girders and the transverse diaphragms stiffness blasted on all floors of the building. The width of the pieces after the collapse of the explosion was about 10 m. The method of calculation of safe distances for various harmful effects of the explosion

Seismic effect of "Destructor" in the destruction of construction

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

The paper discusses the issues of conducting blasting in the destruction of building structures using boreholes instead of the standard explosive knock-free composition – "Destructor". In the course of experiments on the destruction of reinforced concrete slab foundation by "Destructor" was held registration of seismic waves. It is shown that the effect of the seismic action "Destructor" is tens times less than that of regular explosives. According to the maximum oscillation speed of seismic waves was estimated TNT equivalent of "destructor", which in concrete destruction was less 0.0032.

A critical analysis of some provisions federalnych rules and regulations in the field of industrial safety "Safety rules for blasting"

Keywords: industrial safety, norms and rules, technical expert, explosive materials, blasting operations, emergency, casualty

At the end of 2014 in Russia came into force the Federal standards and rules in the field of industrial safety "safety Rules for blasting" (PBBR), which, like the previous rules of Rostechnadzor, according to the author, are not without drawbacks. This article was done with a purpose – to draw the attention of specialists employed in the field of handling explosive materials (VM) on certain provisions PBVR, critically evaluate their usefulness and suitability for their work. Among the identified deficiencies that are not represented by observations on underground blasting, because in spite of the existing practice for the treatment of WM in the underground conditions, the author does not consider himself a specialist, the level of which should correspond to a real expert for underground works, even the lowest category. In this connection, to discuss safety issues in underground conditions in the press, the author urges his colleagues – experienced specialists and experts in the field to submit their comments, maybe it's to save someone's life.

On the question of the need for the creation and implementation of the automated monitoring systems and the account of the displacement in the roof coal mines

Keywords: roof, anchoring, frame depth, offset in the roof, measuring, control, automation, monitoring

Fast and quality of mining makes to the sinking and cleaning techniques high demands for reliability, performance, and a number of other criteria. In turn, coal and rock mass require timely surveys and monitoring of his condition. Continuity and high precision control of the state coal-rock mass will help to predict and avoid dangerous consequences caused by sudden collapse of the roof. These factors and growing quantities of sewage treatment works require optimal methods for the diagnosis and monitoring the state of the roof, which have important properties such as high reliability of the results, the convenience and efficiency of execution of works, as well as to minimize the human and economic costs for their implementation, security implementation. The article discusses the relevance and need for the creation and implementation of the automated monitoring systems and the account of the displacement in the top of the coal mines – as one of the main factors ensure the safety of underground mining of bedded deposits of coal in the future.
