The Impact

Abstract The industrial development of mankind is based on the intensive use of natural resources of the planet. The development of the mining industry is a necessary and important factor for the successful development of the national economy. At the same time, mining has a significant impact on environmental degradation. Methods for assessing and minimizing the environmental impact of mining have only been developed in practice in the last 50 years and differ significantly from country to country. The article analyses the approaches and methodologies for environmental impact assessment (EIA) based on international and national standards. The methods used in Kazakhstan and the countries of the European-Asian Economic Union (EurAsEU) are critically evaluated. The developed mathematical models are implemented in the form of digital solutions and implemented in the module of the cloud system ‘3D Quarry’. The methodology proposed by the authors for use and the developed software product allow optimizing mining operations at quarries according to the parameters of minimizing their negative impact on the environment. At the same time, it is mandatory to comply with mandatory national and international regulations. The proposed 3D Quarry system and the EIA module are an alternative to commercial software products (and their pirated copies, often used by companies in the countries under study) and are aimed at small mining companies in post-Soviet countries. It is expected that the application of the proposed software product will allow, within the technological capabilities, to minimize the impact of quarries on the environment of Kazakhstan.

Mining and sustainable development may be compatible with the priority of measures to reduce impacts on the major ecosystems with severe consequences for the future generations. Infiltration of contaminated water into soils/rocks due to activity of different sectors of mining industry causes increasing concentration of minor and major deleterious elements in natural environment, forcing an economic operator to implement the best available techniques to solve severe environmental problems. The research is aimed at determining heavy metal contents in tailings storage facilities of coal mining operations in the eastern part of JiuValley, revealing mechanism of interaction of the TSF infiltrate with EastJiuRiver, as well as assessing the impact of the TSF on quality of the natural environment. One more aim of the research was to determine the ways by which the TSF components produce negative impact on the soils and surface waters. The obtained results can be fundamental basis for the future researches in the field of closing and maintaining the mining activities in JiuValleyand the land reclamation.

Mining industry faces new technological and economic challenges which need to be overcome in order to raise it to a new technological level in accordance with the ideas of Industry 4.0. Mining companies are searching for new possibilities of optimizing and automating processes, as well as for using digital technology and modern computer software to aid technological processes. Every stage of deposit management requires mining engineers, geologists, surveyors, and environment protection specialists who are involved in acquiring, storing, processing, and sharing data related to the parameters describing the deposit, its exploitation and the environment. These data include inter alia: geometries of the deposit, of the excavations, of the overburden and of the mined mineral, borders of the support pillars and of the buffer zones, mining advancements with respect to the set borders, effects of mining activities on the ground surface, documentation of landslide hazards and of the impact of mining operations on the selected elements of the environment. Therefore, over the life cycle of a deposit, modern digital technological solutions should be implemented in order to automate the processes of acquiring, sharing, processing and analyzing data related to deposit management. In accordance with this idea, the article describes the results of a measurement experiment performed in the Mikoszów open-pit granite mine (Lower Silesia, SW Poland) with the use of mobile LiDAR systems. The technology combines active sensors with automatic and global navigation system synchronized on a mobile platform in order to generate an accurate and precise geospatial 3D cloud of points.

Mining Plant

Environmental protection law and geological and mining law require the mineral mining plant to protect its surroundings from the effects of mining operations. This also applies to the negative impact of vibrations induced by blasting works on people and construction facilities. Effective protection is only possible if the level of this impact is known, therefore it is necessary to record it. The thesis formulated in this way has been and continues to be the guiding principle of the research works carried out in the AGH Laboratory of Blasting Work and Environmental Protection. As a result of these works are procedures for conducting preventive activities by open-pit mines in order to minimize the impact of blasting on facilities in the surrounding area. An important element of this activity is the monitoring of vibrations in constructions, which is a source of knowledge for excavation supervisors and engineers performing blasting works, thus contributing to raising the awareness of the responsible operation of the mining plant. Developed in the Laboratory of the Mine's Vibration Monitoring Station (KSMD), after several modernizations, it became a fully automated system for monitoring and recording the impact of blasting works on the surrounding environment. Currently, there are 30 measuring devices in 10 open-pit mines, and additional 8 devices are used to provide periodic measurement and recording services for the mines concerned.
