A method of determining the errors of segmented GRID models of open-pit mines constructed with the results of unmanned aerial photogrammetric survey
The methodology of building a digital elevation model based on the results of aerial photogrammetric survey from an unmanned aircraft is proposed, which is based on the division of the initial point cloud into equal segments. This allows, having made an assumption of the linear character of change of height of points in a separate segment, to approximate them by separate planes. RMS errors of the models from the survey data were calculated according to the scattering of the points in relation to the approximating surfaces, which made it possible to reveal the dependence of the model construction error relative to the sizes of their constituent segments, as well as to propose a method for filtering the cells containing outliers with respect to the expected model error. The proposed method was tested on the models of three mining objects – limestone quarry, phosphogypsum dump, and peat cut. The experimental results showed a multiple reduction in model error compared to standard DEM models providing the required accuracy for mining documentation.

Decrease in coal losses during mining of contiguous seams in the near-bottom part at Vorkuta deposit
- Authors:
- Oleg I. Kazanin
- Valeriy V. Yaroshenko
The problem of formation of extended zones with high rock pressure (HRP) from safety pillars at the boundaries of extraction pillars formed due to the mine layout of complex geometry is considered at the example of JSC Vorkutaugol mines. A detailed analysis of the remaining reserves of the near-bottom part of the deposit was carried out to estimate losses and the impact of HRP zones from the Chetvertyi protective seam to mining operations on the Troinoi upper seam along with the possibilities for the reduction of sizes of HRP zones at the account of expanding the underworked space. Due to research on the near-bottom part of the Vorkuta deposit, within the framework of the accepted layout, a zone at the Komsomolskaya mine and two zones at the Zapolyarnaya-2 mine were singled out, at which losses at the boundaries of the extraction pillars amount up to 13-22 % of the total resources of the mine field. The high volume of losses in these pillars indicates the relevance of research on the priority extraction impact of protective seams on the efficiency and safety of mining operations in the working area of underworked and HRP zones. Based on the analysis of foreign and Russian experience in the pillar cleaning-up at the boundaries of working areas and the methodical guidelines and instructions, a technological scheme was developed that allows increasing the coal mining recovery factor in the near-bottom part of the Vorkuta deposit from 0.75 to 0.9 without fundamental changing of the ventilation and transport networks and also without purchasing any additional mining equipment. The conducted economic calculations confirmed the effectiveness of implementing the new technological scheme for cleaning-up reserves at the boundaries of extraction districts. The economic effect is from 0.079 to1.381 billion rubles of additional profit from coaxial extraction pillars, depending on the mining and geological conditions and the size of the pillars.

Effective capacity building by empowerment teaching in the field of occupational safety and health management in mining
The paper is dealing with a developed concept named Empowerment Teaching, which is based on practical teaching experience gained in various mining universities. It is demonstrated that this concept can be used to increase the effectiveness of knowledge transfer to mining countries in the world, as well as to overcome cultural barriers between lecturers and their students. The two models of participatory training, which are proposed to be named “physical” and “emotional” models, are portrayed. The authors are convinced that participatory training methods can be an ideal answer to a challenge associated with workers’ competencies in mining, namely – the potential of highly motivated and well-educated young academics is often diminished by a lack of ability to apply their knowledge. A special emphasis is made on the possible application of empowerment teaching for educational and training activities in the field of occupational safety and health (OSH), which is a matter of utmost importance for the mining industry. Several benchmarking initiatives in the field of OSH (“safety culture”, zero-accident vision) are underlined to be encouraged and promoted by means of new teaching methods. The examples of successful international cooperation among universities are given, as well.

Assessment of Rock-Burst Hazard in Deep Layer Mining at Nikolayevskoye Field
The paper presents results of conducted research using regional and local methods of forecast and control over geomechanical state of the rock mass at burst-hazardous Nikolayevskoye field, located in a geodynamically active region. The study subject is the ore mass of Nikolayevskoye field, characterized by man-induced and tectonic disturbances and high geodynamic activity. The aim of research was practical implementation of methods and instruments of forecast and control over geomechanical state of the burst-hazardous rock mass and safety improvement of mining operations. Exploitation practice of burst-hazardous fields demonstrates that forecast accuracy of hazardous rock pressure demands cutting-edge multi-level systems, where local methods and tools complement regional ones. A regional forecast of rock-burst hazard at Nikolayevskoye field was performed by means of seismoacoustic method using automated control system for rock pressure (ACSRP) «Prognoz-АDS». Local forecast was carried out using «Prognoz-L» device, geophysical (sample disking) method and visual observations of dynamic pressure manifestations in the mining tunnels. Quality assessment of stress-strain and burst state of the rock mass was performed using specialized software «PRESS 3D URAL». Integration of engineering and geomechanical data in the process of conducting research guarantees a relevant assessment of rock-burst hazard in various areas of the field at various stages of its development. Practical verification of the system, where local methods and tools complement regional ones, demonstrated satisfactory results at Nikolayevskoye mining plant, which makes it recommendable for other mining facilities extracting ore at great depths under similar conditions of active geodynamic processes.

Modern Mathematical Forecast Methods of Maintenance and Support Conditions for Mining Tunnel
- Authors:
- S. A. Ignatyev
- A. E. Sudarikov
- A. Zh. Imashev
The research focuses on mathematical methods of mining pressure forecast to develop rational support patterns for mining tunnels and to ensure safety of mining operations. The purpose of research is to develop the methodology of applying advanced calculation methods and software solutions based on neural networks to reduce dispersion of factors influencing stability of mining tunnels, as well as to define rational parameters of mining tunnel support. The authors review the algorithm of geomechanical process examination, which is divided into several stages. First of all, it is proposed to use cluster analysis to examine location conditions of man-made outcrops, which allows to divide all the diversity of existing conditions for mining tunnel construction. Cluster analysis first allows to reduce the dispersion of factors that influence the stability of mining tunnels in various clusters, and then to determine rational parameters of tunnel support in each cluster. After the problem of cluster analysis is solved, it is proposed to use software programs that allow to study geomechanical processes in each cluster. At this stage, both standard methods (normative techniques, numerical modelling, analogies use, etc.) and the most advanced methods – neural networks – can be applied. Described algorithm of solving geomechanical problems, which utilizes advanced numerical methods and a software package based on neural networks, ensures an individual approach to estimation of mining pressure under varying conditions of man-made outcrop location in the rock mass.

Forecasting rock burst hazard of tectonically disturbed ore massif at the deep horizons of Nikolaevskoe polymetallis deposit
- Authors:
- D. V. Sidorov
- M. I. Potapchuk
- A. V. Sidlyar
The subject of the research is the stress-strain and rock burst hazardous state of the ore massif of the Nikolaevskoe polymetallic deposit, formed under the influence of complex mining-geological and mining-technical factors. The purpose of the research is to establish the peculiarities of the formation of technogenic stress fields at the deposit, which is characterized by a block structure, a complex tectonic system and the presence of a large volume of developed spaces. Volumetric geodynamic modeling of the stress-strain state of the massif at different stages of the development of the deep horizons of the deposit was carried out by collecting information on the structure, properties and geodynamic state of the rock mass. The assessment of stress changes taking into account the effect of hypsometry, the configuration of the selvages, the physical-mechanical properties of the ore deposit and host rocks, the presence of tectonic disturbances was made using the developed numerical algorithms, the automation equipment of the initial data and the PRESS 3D URAL software. The simulation made it possible to establish that tectonic faults in the massif lead to a qualitative change in the stress-strain state in certain parts of the ore massif and in the pillars, namely, the reduction of stresses along the tectonic faults and their growth in nearby pillars. The identified features of the distribution of stresses in the tectonically disturbed rock massif of the Nikolaevskoe deposit will allow to identify in advance potentially hazardous areas both at the planning stage of mining operations and during development, as well as to work out effective rock burst measures to increase the safety of mining. The results of research can be used in enterprises with similar mining-geological and mining-technical conditions.

On the design features of underground multiple gassy coal seam mining
- Authors:
- O. I. Kazanin
The analysis of the industry regulatory requirements and the world design experience of underground multiple coal seam mining is provided. The main problems of intensive longwall mining of multiple flat gassy coal seams as well as methods for determination of high rock pressure zone parameters and seams interaction are considered. The examples of a number of mines in the Kuzbass and Pechora coal basins show that the design of multiple seam mining and the choice of longwall panel parameters were often made without taking into consideration influence of surrounded seams that leads to essential complication of conditions for mining operations and decreases the technical and economic indicators of mining. The existing industry regulations do not allow considering complex influence of factors in multiple coal seams mining fully. On the basis of field, laboratory, and numeric research results it is noted that recommendations for pillar positioning in contiguous seams ensuring efficiency and safety of multiple seam longwall mining can significantly differ in case of liability of coal seams to spontaneous combustion, high natural gas content, influence of multiple seam mining onto daily surface, and difficult conditions of entries maintenance. The importance of having information on the stress-strain condition of the rock mass at a design stage and its changes in the process of multiple seam mining is shown. The need for industry regulations updating for the purpose of a more detailed definition of a form, size and a location of high rock pressure zones as well as stress parameters in these zones is noted. A set of recommendations for effective and safe multiple seam mining is developed.

Systematization of factors to be considered in mine abandonment design
Subsoil is not just a source of mineral resources; it also serves as a burial site of industrial and domestic wastes, a storage place for oil and gas, and an environment for constructing underground facilities and creating preservations and nature sanctuaries. Subsoil area development is intensified and diversified with each passing year, exerting great influence on ecological systems and all their components. Special attention should be paid to terrain as upper facet of lithosphere, submitted to maximal impact of anthropogenic processes. Activation and emergence of natural and anthropogenic processes causes changes manifested in various combinations of negative events. Most important events include deformations of rock mass and land surface: exhaustion and pollution of ground and surface water, waterflooding and swamping of tapped sites, soil dehydration and salinization, air pollution, land site withdrawal from commercial circulation etc.

Comparative analysis of joint and separate adjustment of two points of mine survey triangulation
- Authors:
- V. G. Zdanovich
The article studies the relationship between the errors in the position of two mine triangulation points rigidly inserted into the existing base network, with their separate and joint adjustment. The solution to this problem is of considerable interest to mine surveying practice when replenishing the existing mine triangulation network with new points as mining operations develop. In this case, when inserting new points, the mine surveyor is forced to accept previously determined points as initial ones, due to which sometimes a significant number of stages in constructing the network arises and its accuracy is reduced to a certain extent. The mine surveyor must be able to quantitatively assess the loss of accuracy of network elements caused by separate adjustment of existing and newly determined points, and on this basis decide on the choice of one or another scheme for inserting points and the most appropriate use of the reference network when solving mine surveying and other engineering problems. If the mine network points are determined simultaneously, then preference, of course, should be given to their joint adjustment, since under normal conditions it always increases the weight to a certain extent elements of the network. But even in this case, the results obtained in the article are of interest, since they shed new light on the issue of the relationship between the weights of network elements in separate and joint equalization of the points being determined and allow a more correct assessment of the merits of the latter.

Notes on the derivation of formulas for determining the direction error from the eccentricity of the theodolite or signals
- Authors:
- Z. D. Nizguretskii
For assessing the impact of a design error on the accuracy of transmitting directions to a mine, existing mine surveying guidelines usually recommend formula (1) (see article). Using the same reasoning, a well-known formula is usually derived for assessing the accuracy of measuring angles in polygons depending on the impact of signal and instrument eccentricity. The above conclusion does not answer the question: what kind of error should be understood by the value of ex, which in existing guidelines is usually called the "average linear error" [1] or simply "linear error" [2]. Clarification of the meaning of the error ex is absolutely necessary when making practical calculations, since several characteristics of position accuracy are used in error theory, among which the most commonly used are the average linear error of position and the average linear error in direction.

Taking into account the influence of errors of initial points when assessing the accuracy of mine survey triangulation networks
- Authors:
- V. G. Zdanovich
When using formulas of the theory of errors and the method of least squares for assessing the accuracy of triangulation networks, it is necessary to strive for the most complete consideration of all sources of errors that affect the accuracy of determining the elements of the network. This applies primarily to the influence of errors in the initial data, the issue of taking into account which has repeatedly attracted the attention of geodesists and mine surveyors. In the existing works devoted to this issue, the most detailed solution is based on the direct application of the main formula of the theory of errors to the function of interest to us, which is preliminarily expressed through directly measured quantities (see article). The strict formulas given in the mentioned works, however, are difficult to apply to the analysis of the accuracy of mine survey triangulations, which are usually rigid networks of the lowest construction queues and have a significant amount of initial data. The use of these formulas is associated with the production of very cumbersome calculations that do not have sufficient clarity and hide from the calculator the mechanism of accumulation of errors in the network, thereby complicating the transition to approximate methods of assessing accuracy. To solve some specific problems of assessing the accuracy of network elements encountered in mine surveying practice, it is possible to derive special formulas that solve these problems much more simply and clearly.
