DEVELOPMENT OF THEORY AND MODELING OF PROCESSES OF ARCHING IN THE VICINITY OF A TUNNEL
Geomechanics solves many practical problems. But there are two main, we can say classical tasks of geomechanics is the problem of the stability of mine workings and the problem of earth surface strike shift with the development of mining operations. The first problem appeared from the beginning of mining, the second much later, when education developed space has led to a significant displacement of the overlying rock masses. Development of technology of urban underground construction over the past 50 years aimed at minimizing displacement of the overlapped arrays. However, the task of destruction of soil in the mine working arch or the task of svoeobraznyi remains unresolved to date. The paper presents a formula for determining the load on the tunnel lining.
Key words: geomechanics, physical and technical basis, model, production, finishing, the calculated circuit voltage offset load.

THE ESTABLISHMENT OF THE CRUSHING AREA RADIUS OF FRACTURED STRAINED MASSIF DESTRUCTION DURING EXPLOSION OF TWO PARALLEL CONTIGUOUS CHARGES OF BLASTING COMPOUNDS
Analysis of technical literature has shown that during explosion of parallel-contiguous charges of blasting compounds mathematical formulas for determination radius of destruction of fractured massif that defines the most important parameter − the line of the least resistance are absent.
On the basis of energy theory of deformation and destruction of fractured rock massif by explosion we solved a classic problem of interaction of deformation waves from two charges of blasting compounds exploded simultaneously. According to this theory destructive waves of voltage lose the main part of energy on the nearest to charges natural flaws and the destruction of outlying joints occurs as a result of deformation and fracture by the action of detonation products. In other words, the wave of charge deformation, that is posed as successive displacements of joints followed by inelastic deformation of array on the natural joint’s edges together with its elastic strains and deformation, spreads in the massif.
Practice has shown that classical solution during determining the line of the least resistance underesti-mates this value. Another theoretical problem is solved taking into account effect of massif elastic response, as a result of its pressure between two blasting holes. Accounting for the elastic reaction effect makes it possible to increase the line of least resistance at the same results of explosion. We gave the numeral values of massif’s crushing area radius with different variants of the calculation, which prove the need to consider the effect of elastic massif reaction.
Key words: parallel-contiguous charges of blasting compounds, radius of crushing area, fractured strained massif, effect of elastic massif reaction, line of the least resistance, theoretical formulas, accuracy of formulas.

DETERMINATION OF BREAKING ZONE OF STRAINED FRACTURED ARRAY DURING SIMULTANEOUS EXPLOSION OF SEVERAL PARALLEL CONTIGUOUS CHARGES OF BLASTING COMPOUNDS
During extraction of low powered ore bodies ( power to 3,0 m.) using cross options of mining method, selective breakage of flat deposits and ore preparation for underground leaching, we use breaking method of parallel contiguous charges of blasting compounds more often. At explosion of several contiguous holes the most important parameter is a radius of controlled crushing zone of fractured array transversely to line, which connects the charges of blasting compounds. This article considers an action of 3 and more parallel contiguous charges of blasting compounds on the basis of energy theory of explosive attack on strained fractured rock array. Theoretical formula for calculating radius of zone of controlled crushing during simultaneous blasting of series of charges transversely to flats was formed, the line of the least resistance was determined as well. We conducted a series of technical experimental explosions at sublevel breaking of low powered ores with assessment of coarseness of grading by photo planimetric method in conditions of underground uranium mine № 1 PJSC PIMCU. Comparison of experimental researching results and theoretical calculations (on the basis of parameters of drilling and blasting works and a middle size of a piece) points on their favorable similarity.

In the basis of the developed models of geomechanical state massif, contain of mine working iand geological violation, are two methods – the method of fictitious loads and displacement discontinuity method. The method of fictitious loads describes the boundary conditions on the contour generation, and the displacement discontinuity method formulates the conditions on the banks of the violation. Geological violation is a narrow gap with a filler of resilient material with desired characteristics of stiffness in compression and shear. Within the model the conducted research of the stress state of rock mass around mine working and crevices, in particular, the diagrams of the normal stresses in the roof of the mine working and the soil cracks. The results of these studies show that with certain distances between them in the array experience significant tensile stresses. These stresses in the roof of a drift, and in soil cracks are acting in the horizontal direction. The sizes of the zones of discontinuity in the array that occur around a single mine working, differ slightly from the sizes of similar zones formed in an array around an excavation and cracks. The maximum difference of values of the coefficient of dislocation for these cases is about 7 percent.

REGULATORY FRAMEWORK FOR MINING EQUIPMENT QUALITY AND SAFETY CONTROL IN DESIGN AND CONFORMANCE EVALUATION
This work presents the results of investigation of the structures formed by flocculation of fine coal preparation products suspensions. Consideration of flocculation structures formation was carried out on the base of the extended DLVO theory with taking into account the amount of polymer macromolecules on one particle of known diameter. It was shown that the particles of the solid phase with diameter more than 1 μm are flocculated by ortokinetic way for a few seconds and submicron particles are flocculated on perikinetic way for 400–600 seconds. On the base of the theory of fluids flow in capillary-porous media it has been developed and experimentally validated a model describing the kinetics of flocs mechanical syneresis. It was shown the possibility of reducing of the water content of coal froth flotation concentrate cake by mechanical syneresis and, accordingly, cost decrease of concentrate thermal drying. Theoretical analysis of flocculation structures strength for maximum shear strain state, allowed to calculate the maximum shear yield stress depending on the diameter of the particles and the flocculant dosage. Rheological study on coal froth flotation concentrate showed that the nature of these suspensions without flocculants are close to Newtonian plastically fluids, and using flocculants are pseudoplastic properties. Experimentally obtained values of shear yield stress for coal froth flotation concentrate not contrary with theoretically calculated one. Also the approach for evaluating the effectiveness of suspensions flocculation conditioning based on experimental determination of filtration and structural-mechanical properties of filter cakes was proposed. The obtained results allow to predict the performance and speed of the belts. To perform the necessary calculations in this work was the interrelation between hydrostatic pressure and drainage time was established.

ECONOMICAL AND THEORETICAL ASPECTS OF MARKETING AT THE MINING ENTERPRISES
In article single economical and theoretical questions of marketing at the mining enterprises are considered.
It is noted that at full realization of criteria of marketing requirements as seller, and the buyer have to be met. Requirements of the seller and the buyer of production have to be provided on the basis of efficiency of business which main condition expresses equality of the discounted cost of future net income of the buyer (the enterprise uses cars and the equipment for production of concrete production) and investments, expenses, expenses of the seller (manufacturer of cars and the equipment).
Effective development of market structure is carried out in the direction of dokhodooriyentirovanny economy. Dokhodooriyentirovanny economy – economy with release and realization of competitive production, that is the economy focused on continuous introduction of innovative solutions by production of production delivered on the market. The Dokhodooriyentirovanny economy defines a tendency in approach to market structure of the perfect competition. To Dokhodoorintirovanny economy use of high-performance cars and the equipment, a high salary of workers, increase in volumes of release and delivery to the market of the realized production is characteristic. The aspiration to decrease in prime cost of unit of products due to increase in production is peculiar to Dokhodoorintirovanny economy.
Marketing activity is especially important in the conditions of low competitive economy. Low competitive economy – the economy which is on production and delivery to the market of production in insignificant volumes and the limited range. Such economy has to seek for achievement of level of dokhodooriyentirovanny economy. In low competitive economy the enterprises of market structure of the imperfect competition (monopoly, a duopoly, a monopsony, an oligopoly) function. To low competitive economy use of low-productive cars and the equipment, a low wage of workers, use of cheap materials is characteristic. The aspiration to economy of expenses and expenses without attraction of new technology, new high-performance equipment due to decrease in outputs is peculiar to low competitive economy. For low competitive economy existence of growth of prime cost of a unit of production is characteristic. Functioning of the enterprises of low competitive economy demands performance of strict ratios in change of rates of the main technical and economic indicators of production economic activity: prime costs of a unit of production, labor productivity and volume of production; costs of production and profit.
Key words: economical and theoretical aspects, marketing, mining enterprises, market of the seller, market of the buyer, innovation, dokhodooriyentirovanny economy, low competitive economy, technical and economic indicators, production economic activity.

Experience of Priargunsky Mining and Chemical Works in the area of integrated rockburst hazard monitoring in underground mining in Streltsovsky ore field featured with complex geomechanical situation and high rate of injuries on deep levels is described.
The article presents automated rock pressure control system ARPC, including network of underground geophones and digital transducers for continuous recording of dynamics of mechanical processes.
For continuous seismo-acoustic monitoring and regional rockburst hazard forecasting, the author describes automated wide-range rock pressure control system AWRRPC—PROGNOZS developed at the Institute of Mining of the Far East Branch of the Russian Academy of Sciences. The geomechanical monitoring system enables detecting increased stress zones in rock mass and higher energy micro-displacements of rock blocks in the course of stoping and allows visualizing such migrating sources and places of seismo-acoustic activity.
The author describes systems meant for remote monitoring of deformation in tunnels, mines and subways as well as for preset-time data collection and storage in non-volatile memory of SMD-KM unit of the system with option of data transmission and live browsing on a PC. The system supports round-the-clock operation in the mode of low energy consumption. This method allows real-time detection of inelastic strain zones in mine workings and control over hazardous plastic strain zones at Antei deposit.
For safety of mining and reduced risk of production suspension, work areas at Antei deposit are equipped with DIAMEC-232 core drilling rig for non-productive drilling and rock stress state assessment using core disking method.
The application of the rock pressure control system with the option of data transmission and live browsing on a PC allows advanced forecasting of rockburst hazard and finding of areas in rocks that need destressing and occupational safety enforcement.

ACTIVE GEOELECTRICAL AND SEISMOELECTRICAL MONITORING OF STATE OF THE GEOLOGICAL ENVIRONMENT
Principles of active geoelectrical and seismoelectrical monitoring are considered in the article. Question of measurement technique optimization by geoelectrical monitoring are considered. The results of experimental investigations of method on laboratorial facility, constructed for research of formation and evolution of underground caverns, are presented. For seismoelectrical monitoring, the results of laboratorial investigation of transformation of seismic energy in electrical energy in rocks are presented. Both forced oscillation mode and self-oscillation mode are considered. Self-oscillation mode appears by formation of positive feedback in system «acoustic transducer – rock sample – measurement electrodes». For example, the results of experiment as very small dose of fluid (sweet water) influences parameters of seismoelectrical transformation are gave. The results of experiments with other fluids are reviewed. Resume about ability of application of geoelectrical and seismoelectrical monitoring for geological environment control by anthropogenic impact are made.

CHARACTERISTICS OF THE ACTIVE FAULT STRUCTURES ACCORDING GEOELECTRICS CONTROLLED SOURCE
Methods geoelectrics controlled source (transient electromagnetic sounding, vertical electrical sounding, electrical resistivity tomography) are used for monitoring the electrical parameters of the geological massif, under the influence of natural and anthropogenic geodynamic processes. The main goal of such work is the prediction of natural hazards, landslides, rock bursts, suffoziozno-subsidence processes in the mining, quarrying, located in seismic areas, or exposed to strong anthropogenic influences. The fault fractured zone, available in sediments and geological foundation of the array may be seismogenerating, so the definition of their activities is an important task.
For data analysis, electromagnetic monitoring of the electrical parameters considered two – electrical resistivity and coefficient of electrical anisotropy. Estimates of variations of these parameters and their comparison with the intensity of the elements of fault tectonics makes it possible to assess the degree of fault activity revealed violations. Using the two parameters increases the information content of the study.
Key words: non-stationary electromagnetic sounding, vertical electric sounding, electrical resistivity to-mography, electromagnetic monitoring, variations of the electrical resistance, the coefficient of electrical anisotropy, activity of fault disorders.

UNIFIED APPROACH TO MODELLING AND CONTROL OF TECHNOLOGICAL TRANSPORT
Possibilities of different approaches to transportation systems modelling are analyzed. The main topic of the paper is the problem of general representation of technological transport motion within a spatially distributed industrial and/or logistic object. The general model of such transportation process is developed in the form of a hybrid system (an event-switched process), i.e., a system with qualitative and quantative dynamics which state changes on switching hypersurfaces. The model is a set of relationships of the following types:
1) ordinary differential equations representing continuous dynamics of active elements while the qualitative state does not change; 2) condition of switching, i.e., qualitative changes of the process in question; 3) formulas of state transformations due to switching events; 4) constraints on controls, pertaining both to stages between switching events and to switching events. Elements of the general model are exemplified with representation of dynamics and control choice for transportation units and loaded or unloaded stores (concentrators).
Different ways of description and choice of controls are presented, namely as given control laws that may express different algorithms of operative dispatch, interactive control choice and solution of local optimum control problems. Possibilities of the model use for current prognosis and operative control as well as organisation of simulation aimed at substantiation of both control system and th
