With the deepening of open pit mining, the volume of worked out space increases and, along with it, the potential capacity for storing overburden. At the same time, the pits completely allocated for the internal dumps are used only by the end of the period of the open pit operation. The known theoretical approaches to determining the location of the internal dump are little implemented in the practice of surface mining, which is explained by two reasons. First, standard design solutions are based on wellknown theoretical provisions; secondly, a formalized template approach to substantiating certain design developments in the field of dumping of internal dumps prevails, which pushes them towards their fragmentary rather than integrated implementation. With regard to the conditions of the Kuzbass open-pit mines, the article proposes a modernized interpretation for the formation of structural schemes of the sequence of quarry fields on the basis of constructive-and-parametric studies of a multivariate adaptation of the internal dumping mode.

The Relationship

Today, up to two-thirds of the world’s minerals are mined in an open, more economical way. However, at the same time, billions of tons of overburden are extracted, which are piled in the dumps, where they are polluted, lose their value and, in addition, reduce the quality of the environment. The possibility of industrial use of various rocks of from quarry field characterizes the complexity of minerals extracted by surface mining. Currently, there are no clear criteria for determining the size of blocks when designing enterprises for open pit mining. In most cases, when designing open pit mines, a quarry field is conventionally divided into several blocks, which does not always ensure the optimal production capacity of the mining enterprise due to the uneven distribution of reserves in the block contours. Because of that, during the transition from one block to another, a decrease in the production capacity of the enterprise can be noted. To avoid productivity decreasing, the precise analysis of the block parameters must be performed.

Chernogosky open pit mine integrates truck-and-shovel system of mining with overburden rehandling to internal dump with a set of walking excavators for rehandling of overburden to mined-out area of the pit. It is possible to improve efficiency of stripping in the conditions of Chernogorsky OPM by reducing percentage of stripping with more expensive handling system. The relevant research and solutions to this effect are presented in this article. Comparative characterization of mining conditions and parameters of mining systems applied is given for open pit mines Chernogorsky, Turnui, Nazarovsky, Vostochno-Beisky and Izykh. The comparative analysis points at the need to account for difficulty of mining and process sites in comparison of equipment productivity. High concentration of mining machines, which is conditioned by narrow mining front and simultaneous operation of five faces, as well as blasting operation implemented every 1-2 days, are recognized as the main constraints of excavator capacity in mining with direct dumping in Chernogorsky open pit mine. The management and engineering solutions implemented in the mine and resulted in higher efficiency of draglines are described.

This research article presents a software module for the environmental impact assessment (EIA) of open pit mines. The EIA software module has been developed based on the comprehensive examination of both country-specific (namely, Kazakhstan) and current international regulatory frameworks, legislation and EIA methodologies. EIA frameworks and methods have been critically evaluated, and mathematical models have been developed and implemented in the GIS software module ‘3D Quarry’. The proposed methodology and software module allows for optimised EIA calculations of open pit mines, aiming to minimise the negative impacts on the environment. The study presents an original methodology laid out as a basis for a software module for environmental impact assessment on atmosphere, water basins, soil and subsoil, tailored to the context of mining operations in Kazakhstan. The proposed software module offers an alternative to commercial off-the-shelf software packages currently used in the mining industry and is suitable for small mining operators in post-Soviet countries. It is anticipated that applications of the proposed software module will enable the transition to sustainable development in the Kazakh mining industry.

Response Plan

At present, in the Russian Federation there are no legislatively approved recommendations on the procedure, structure and requirements for the design of an emergency response plan for coal open-pit mines. Therefore, the development of this document at the mining enterprises is carried out independently, coordinating it with emergency response services serving the hazardous production facility. The absence of regulatory documents forces the enterprise management to make decisions on the structure of the document, forms and its content. This can lead to errors in conducting mine rescue operations when attracting additional forces and means from other units of rescue units. The relevance of creating a single document for everyone to draw up a plan for the elimination of accidents at sections has been repeatedly noted at production meetings with the participation of scientists, specialists from surveillance services and representatives of rescue units. In order to increase the emergency preparedness of enterprises, on the basis of studies of the current regulatory documentation of Rostechnadzor, the EMERCOM of the Russian Federation, Mines Rescue Service and scientific literature, an algorithm was developed for compiling submarines for coal open-pit mines. The analysis of accidents at the coal open-pit mines of the country made it possible to create a list of types of accidents encountered. Based on this, instructions have been developed for the actions of all workers in the mine for the initial period in the event of an accident. Taking into account the existing standard forms for coal mines, the developed document forms for open pits were developed, this will make it possible to unify emergency rescue operations regarding the preparation of documents. Scientifically sound solutions can be used to develop a plan for the elimination of accidents in the future at all mining enterprises engaged in open mining. The results of the work expand knowledge in the field of safety of coal open pit mining.

Information about the geological structure of Kuznetsky coal basin (Kuzbass) allows us to note that coal deposits developed by open-cast method are characterized by complicated conditions and have the following features: large length of deposits at significant depths of occurrence; coal series bedding of different thicknesses (from 1 to 40 m); different dip angles (from 3 to 90º); a significant number of dip and direction disturbances; different thickness of unconsolidated quaternary sediments (from 5 to 40 m); a wide range of strength values of rocks. In addition, there is a thickness irregularity and frequent variability of elements of occurrence of coal seams within the boundaries of a quarry field both in length and depth of mining. From the point of view of open-pit mining, such deposits are complex-structured. The factors listed above have a decisive influence on the choice of technical means, the order of development and the possibility of carrying out surface mining operations. Therefore, there is a need for a systematization of mining and geological conditions for the development of coal deposits, the purpose of which is to ensure a process of evaluation of complex-structured coal deposits for the development of coal-bearing zones by various complexes of equipment.

Reducing the costs of the transport component, reaching up to 50% or more of the total cost of the mined coal, is an urgent task that does not require additional confirmation. Since the development of measures to improve the purely technical indicators of motor transport at open-pit mines is beyond the scope of the general study, we will limit ourselves to the search for technological solutions that can have a positive impact on the overall cost of production. This may include, for example, the search for solutions to reduce the duration of the transport cycle and optimization of its components. It is also necessary to study the possible changes in the indicators of the transport technology of open-pit mining when using classic open-pit dump trucks and autonomous heavy platforms (unmanned open-pit haul trucks). The article presents an analysis of existing technical and technological solutions and research on the use of unmanned transport technologies. It is established that the parameters of transport technology will change to some extent with the introduction of unmanned heavy platforms, which will inevitably lead both to the correction of the existing regulatory documentation, and a possible revision of the classical postulates of open-pit mining.

Landscape Alteration

Surface mining activities support socioeconomic development but also cause significant landscape alteration and degradation. By definition, the concept of landscape requires observers; thus, the way mining landscapes are actually observed needs to be taken into consideration for mitigating visual nuisance from open pit mines. This paper utilizes eye tracking techniques for recording and rendering the actual attention patterns of observers, along with saliency models that ‘predict’ the focus of attention in mining landscape photographs. As it turns out, saliency models can aid in reliably anticipating the attention focus across a range of different mining landscapes.

Angle Of Rotation

Hydraulic excavators currently used at open pit mines, in particular backhoes, are more maneuverable, mobile and have more digging capabilities than rope shovels. This makes them suitable for a variety of conditions: top and bottom digging, loading lower, higher and at the standing level. The variants of mutual arrangement of the excavator and the dump truck, respectively, affect the duration of the excavator cycle, which, in turn, directly affects the productivity of the excavator. This article evaluates changes in the productivity of an excavator, depending on its angle of rotation and options for digging and loading. It is determined that the smaller the swing angle of an excavator, the greater its impact on productivity. Based on the executed calculations relative decrease in productivity (in percent from the most optimum variant) is established. Results of work can be used at planning of open pit mining for the purpose of definition, for example, speed of mining front movement at change of parameters of an excavator face and a type of a digging and loading.

The development and utilization of mining resources are basic requirements for social and economic development. Both open-pit mining and underground mining have impacts on land, ecology, and the environment. Of these, open-pit mining is considered to have the greatest impact due to the drastic changes wrought on the original landform and the disturbance to vegetation. As awareness of environmental protection has grown, land reclamation has been included in the mining process. In this study, we used the Shengli Coalfield in the eastern steppe region of Inner Mongolia to demonstrate a mining and reclamation monitoring process. We combined the Google Earth Engine platform with time series Landsat images and the LandTrendr algorithm to identify and monitor mining disturbances to grassland and land reclamation in open-pit mining areas of the coalfield between 2003 and 2019. Pixel-based trajectories were used to reconstruct the temporal evolution of vegetation, and sequential Landsat archive data were used to achieve accurate measures of disturbances to vegetation. The results show that: (1) the proposed method can be used to determine the years in which vegetation disturbance and recovery occurred with accuracies of 86.53% and 78.57%, respectively; (2) mining in the Shengli mining area resulted in the conversion of 89.98 km2 of land from grassland, water, etc., to barren earth, and only 23.54 km2 was reclaimed, for a reclamation rate of 26.16%; and (3) the method proposed in this paper can achieve fast, efficient identification of surface mining land disturbances and reclamation, and has the potential to be applied to other similar areas.

This article is devoted to the issues of processing and analysis of heterogeneous information related to the functioning of mining transport equipment, which becomes available for analysis within the framework of modern technological operations control systems in open-pit mines. These issues are very relevant to robotized technological operations. The paper gives a brief overview of the modern landscape of the autonomous haulage systems management problems, the features of the platform approach to solving the problem of managing unmanned transport and technological processes in open pits are considered. The concept of an agent-based approach to the modeling of an open-pit mining is described in detail on the basis of the interaction of three systems: technical, infrastructural–technological, and geostructural. Some features of the developed platform architecture integration of heterogeneous information are discussed. The principles of information integration are considered in detail when constructing a dynamic 3D model (digital twin) of infrastructure and technological system elements using large arrays of telemetric data. The results of building digital models of open-pit technological roads are presented. The resulting models are comparatively analyzed in the process of optimizing of the interaction of technical autonomous mobile agents and elements of technological infrastructure.
