Proportionality and Cyclicity of the Quarry Working Area Development

The mining science, unlike many other technical sciences, studies the processes that occur not in one place, but in moving faces. The primary task is to analyze the influence of the various factors defining the parameters of the quarry operational area and to define a possibility of mining operations’ concentrating on the individual sections of the quarry, taking into account their further development downdip and in-depth. The intensity of their movement depends on the surface and on the excavating equipment capacity. The development of open pit mining area in time and space is subject to certain rules. Thus, the initiating works providing the access to the deposit should be ahead of the work on the preparation of excavation blocks, and the latter coal extraction. The intensity of the implementation of this works is also associated with certain patterns of the quarry working area development. The article describes the calculation method for determining the cyclical size of the working area, as a function of some key points: the time of working area development; its speed vector; the direction of the depth of mining and the quarry field area.

Coal Reserves

At the present time on the fields of operating and closed-down mines there are sections of open-pit operations. However, the adopted technology does not meet environmental requirements, there are no scientific recommendations on the technology of open-pit mining in hazardous areas of mine fields, there is no substantiation of the boundary contours of open-pit mining. A characteristic feature of depleted mine fields is the disturbed rock mass and the lack of concentrated coal reserves within their boundaries. In fact, coal reserves are represented in the form of fragmentary volumes of safety pillars and substandard reserves in places of geological disturbances. Limitation of mine fields in terms of various infrastructure objects imposes special requirements for mining operations. In these conditions it is not possible to apply the classic mining systems and technologies. This predetermines the necessity to develop new technological solutions. Therefore, scientific research on justification of technology for extraction of remaining reserves of coal after underground development of inclined and steep-sloping coal deposits with simultaneous reclamation of disturbed lands is actual.

This open-pit mining activity has a very helpful environmental potential, soil chemistry, erosion and sedimentation. Change in land use from mining actively after mining requires land and energy closure to ensure that the land is safe for and returned. In accordance with the local spatial pattern in Muara Enim, South Sumatra, the transfer of post-mining land after the dismissal of mining operations will be used as a conservation area managed by the mining community. The concept is an environmental addressing plan to determine the sustainability of various aspects of community life, including local sustainability, food environment, awareness, biodiversity, and sustainability. This study aims to ensure community sustainability after mining operations. The methodology that is an interview with Experts. The results of this research indicate that community empowerment in mining area can use one of the community's natural resource management strategies to ensure social sustainability with land use as agroforestry and integrated agricultural industries.

Mining Areas

At a number of large open pit mines in Kuzbass, coal production costs have increased due to the deepening of mining operations. In order to reduce them, separate sections of coal mining at the upper horizons are operating or are being designed for mining at low current stripping ratio. For the same purpose, open-pit mining areas at the fields of existing quarries are operated and designed. Examples of such existing and projected areas are: the “Complex Synclinal” area at the Krasnobrodsky surface mine; the “Prirezka” area at the Chernigovsky surface mine; a number open-pit areas at the underground mines; etc. The main factors complicating the involvement in the development of new sites are: the presence of residential areas, industrial buildings and structures near the boundaries of the mining area; power supply lines, transport communications, which limits or excludes the production of mass explosions in the preparation of overburden for excavation; limited size or lack of areas for external dumps at a short distance from the site (in some cases, it is possible to close the mined-out space of the worked-out quarry field). When designing the development of areas characterized by such conditions, it is necessary to consider the application of new technical and technological solutions.

Suitable Form

Ecological problems in the open pit mining of coal deposits are extremely hard, since mining operations are accompanied by disturbed land to a large depth with significant changes in the landscape, hydrometeorological conditions, mixing of rocks and removal of infertile or even harmful rocks with radioactive isotopes to the surface. Disturbed lands are unusable if they are not repaired. All man-made disturbances of the environment caused by open pit mining are divided into landscape (changes in terrain, vegetation and soil cover) and environmental (violation of living conditions within the allotment and adjacent lands: changes in water regime, pollution of the soil, air and water basins) onesOne of the most important areas in the field of environmental protection is the reclamation (restoration) of the earth’s surface. In accordance with the requirements of the protection of the subsoil, enterprises engaged in the development of mineral deposits are obliged at their own expense to bring disturbed lands into a state suitable form for their further use. Reclamation of ought to be carried out during open pit mining operations and must be completed after mining of mineral resources in the terms established by the authorities that provide land for use.

Gis Software

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.
