Large-scale mining disturbs wide areas of land. The development program for the mining industry, with an expected considerable increase in production output, aggravates the problem with even vaster territories exposed to the adverse anthropogenic impact. Recovery of mining-induced ecosystems in the mineral-extracting regions becomes the top priority objective. There are many restoration mechanisms, and they should be used in integration and be highly technologically intensive as the environmental impact is many-sided. This involves pollution of water, generation of much waste and soil disturbance which is the most typical of open pit mining. Scale disturbance of land, withdrawal of farming land, land pollution and littering are critical problems to the solved in the first place. One of the way outs is highquality reclamation. This article reviews the effective rules and regulations on reclamation. The mechanism is proposed for the legal control of disturbed land reclamation on a regional and federal level. Highly technologically intensive recovery of mining-induced landscape will be backed up by the natural environment restoration strategy proposed in the Disturbed Land Reclamation Concept.

The Cost

In recent years, there has been a decline in the efficiency of coal mining by traditional methods. On the one hand, the volume of coal outside the contour of the cut, which is economically impractical for open-pit mining, is increasing. On the other hand, when using underground geotechnology, the cost of production exceeds the cost of performing mining operations using open geotechnology, this is due to differences in the factors of operation of the open pit and the mine. This circumstance determines the use of open-underground technology for mining coal reserves outside the contour of the open pit as an actual and promising direction. This article describes a methodological approach based on the use of technological schemes for the preparation and treatment of reserves of powerful shallow coal seams, the justification of the parameters of combined geotechnology with a coordinated and balanced development of open and open-underground mining operations with the distribution of reserves for open and open-underground mining of coal reserves beyond the limit contour of the open pit, the preparation of excavation sites directly from its workings and the coordination of production capacity and the speed of their development. Its application will increase the production capacity of the coal mining complex without additional environmental burden and will provide an increased return on investment.

Phased Development

A 3D model of optimal contours phased development of oval-shaped open pit mines is proposed in the article. It is assumed that with enough accuracy the volumetric contour of the open pit mine is interpolated by an elongated elliptic hyperboloid. The calculation formulas for mineral resources are derived and optimal volumes of overburden are determined depending on the mining phase. In this case, the total number of mining phases is set in advance. The stripping ratio is used as a quality criterion of the optimization task. The problem of optimal control is solved using the Bellman function in dynamic programming. All the necessary calculation formulas are obtained in the final form by solving the optimization problem. Their simplicity and substantiation of each conclusion ensure that the results of this study can be successfully applied in practical calculations of the design and planning of mining operations in open pit mining.

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.

Event open-pit mining methods in the exploitation of limestone by PT Semen Baturaja (Persero) Tbk cause depletion of water, air, and soil. At the end of mining activities will leave ex-mine land in the form of void and non void (empty land). Reclamation and Postmining must be carried out by the company according to the mandate of Government Regulation No. 78 year 2010. Reclamation and post-harvest activities on ex-non void mines can be revegetation activities, while void can be used as reservoirs for raw water sources. The aim is to maintain the sustainability of natural resources and water in the limestone mining environment. The research aims to determine the condition of void water produced from limestone mining activities for a sustainable environment. The method used in this study is using the pollution index method. The results showed that the water in the sump inlet and quarry outlet experienced mild pollution. Pollution index at the location of the limestone mine sump inlet worth 2.14 and for oulet quarry worth 2.07. This shows that mine void water is not feasible to be used as raw water, so water treatment needs to be done so that it meets the established quality standards. If void water comply the prescribed quality standards, environmental sustainability in the limestone mining sector can be achieved during during the life of the mine, post mining, until after the post-mining period.

The cost of technological transport in open-pit mining for medium-depth quarries reaches 50 % of the total cost of production of commercial ore, and for deep-exceed this figure. Therefore, optimization of quarry transport systems is an important element in improving the efficiency of mining. The most important element of optimization is through her character the use of optimization to all linked processes on the basis of objective criteria of efficiency, unity and objectivity of the source data, using multilevel data from sensors mounted on the mining and transport machines to total economic values for processing. A promising direction for the implementation of tools for optimizing the processes of open pit mining and in particular transport systems of quarries, as one of the most important subsystems, is the end-to-end digitalization of mining production. The article presents the results of research and methodological approach to the creation of methods of optimization of complex transport systems on the basis of complex computer modeling, both simulation and economic and mathematical. The concept of TSC optimization methods in the absence of expressed maxima or minima of the parameters reflecting the optimization parameters is proposed. The possibilities of optimization of transport systems due to controlled transients are shown, it is established that the rational organization of the transition process provides cost savings of up to 2 times or more. The concept of a dynamic model of the quarry transport system development, reflecting the transition processes in its formation, is presented.

Abstract Illegal open pit mining might be a very dangerous activity both for the environment and also for the people living in its neighbourhood. This kind of activity is connected with environmental degradation, disruption of sustainable development and lack of the most critical last stage of the mine’s “life”, i.e. land reclamation. An additional element connected with illegal exploitation is the fact of breaking the law and stealing mineral resources. Monitoring of illegal exploitation is therefore an important aspect. The presented here review was intended to investigate which methods can be used directly to detect open pit mining sites and to evaluate their effectiveness. In the reviewed works a wide variety of methods have been used, ranging from manual methods, such as photo-interpretation, to a combination of automatic methods and photo-interpretation, to fully automatic methods. Based on the analysis, it was indicated that different types of classification (supervised, unsupervised, hybrid) are the most commonly u sed. Besides, radar interferometry, image fusion techniques, or images spectral similarity are also used.
