Abstract:

Selective mining of complex structured ore bodies will enable increased iron content in the mined ore mass in underground mining at Kryvyi Rih iron ore basin applying the existing mining systems. The article determines the way the grade changes in a mine block of a complex structured ore body when applying bulk and selective mining as well as factors influencing indices of extracting ore mass from the block. The investigation results prove that it is reasonable to mine complex structured ore deposits with barren inclusions applying selective mining if the iron content in the block varies from 64 to 67% and horizontal thickness of the barren inclusion makes 4 – 12 m. At that, the thickness ratio should not exceed 0.3. Stoping methods should be applied to receive high indices of ore mass extraction. There is determined an ore/barren inclusion-to-ore body thickness ratio considering the dilution factor that confirms practicability of selective mining of complex structured ore bodies. Selective mining of complex structured ore deposits of Kryvyi Rih iron ore basin applying open stoping enables increasing the mined ore mass quality without considerable capital and operating costs and, consequently, staying on the market and enhancing the environmental situation in the region.

Abstract:

This paper deals with the contemporary state of soil cover around the Mid-Ural iron ore deposit, focusing on geochemical features. Sample plots were laid based on the technogenic impact in the study area. Soil samples were taken in the zone of the iron ore deposit, in the zones of overburden and gold mining waste dumps influence, and in the rock blasting site. A total of 64 sample plots were laid. Soil samples were sampled incrementally by an envelope method from a depth of 0.00–0.03 m. Soil texture, physicochemical features, and total heavy metal content (V, Mn, Ni, Cu, Zn, As, Cd, and Pb) were defined for the soil samples. As a result, the evaluation of heavy metal soil pollution under the influence of iron ore deposit mining is given. Chemical contamination of soil was assessed by a cumulative chemical contamination index. Geochemical series of elements formed under the influence of iron ore deposit mining, as well as overburden and gold mining are given. Here, geochemical patterns of heavy metal distribution in the soil of iron ore deposit and under the gold mining influence are considered. The analysis of gold mining influence on the elementary composition of soil revealed the anomalous content of Mn and Ni.

Abstract:

Purpose. To improve of the sub-level caving mining methods during mining of deposits of high-grade iron ores by applying a rational mode and intensifying the ore drawing. Methodology. It included an analysis of scientific literature, design documentation and the practice of mining of deposits of high-grade iron-ores in complex geomechanical conditions of deep horizons of mines, to establish the formation of fundamentally new foundations of scientific-and-design solutions for the rational extraction of minerals; numerical (application a special computer software package PFC 3D) and physical (based on the application of volumetric physical models and equivalent materials) modeling of ore drawing, aimed at identifying regularities of recovery process depending on the mining-geological and mining conditions of the mining of deposits, and also the physical- and-mechanical properties of the loosened ore mass. Findings. Regularities of changes in the qualitative and quantitative recovery percentages depending on the intensity of the ore drawing and physical-and-mechanical properties of the ore have been established using numerical and physical simulation. The obtained regularities made it possible to substantiate the rational parameters of the structural elements of the technological scheme for drawing and delivery of ore. A linear-alternating condition of ore drawing was developed, which will ensure an increase in the extraction of pure ore up to 10% and, as a result, up to 4.6% of quantitative and up to 5.2% of qualitative indicators of ore percentages, as well as up to 1.5% of absolute quality of mined ore mass. Originality. Power-law dependencies of the change in the angle of ore tapping on the intensity of the ore drawing and the ultimate strength of the ore for uniaxial compression have been established as well as dependencies of the increase in the volume of the tapping figure, when a linear-alternating condition of ore drawing is applied, on the intensity of the ore drawing, the height of the collapsed ore layer and the ultimate strength of the ore for uniaxial compression. Practical value. A linear-alternating condition of ore drawing has been developed, the implementation of which in practice makes it possible to increase the qualitative and quantitative recovery percentages and eliminate the human factor while observing the ore drawing planograms.

Abstract:

The present paper considers aspects of underground iron ore mining in Ukraine, in particular the level of mine production and reserves of basic ore fields. It analyzes and generalizes the practice of using cemented rockfill under difficult mining and hydrogeological conditions of the Pivdenno-Bilozerske high-grade iron ore field. The Belozersky iron ore district is the only one in Ukraine that, without any technological cycle of beneficiation, can provide both domestic and foreign consumers with high-quality raw iron ore as required by world markets. The PJSC Zaporizhzhia iron ore plant extracts iron ore from the Pivdenno-Bilozerske field with an iron content of more than 60% using the low-waste, environmentally friendly technology of backfilling the mined-out area with a hardening mixture. The peculiarities of the technology for steep deposit mining and the main processes of backfilling operations in terms of preparation, transportation, and construction of the backfill mass with its stability assessment are explained in detail in this paper. As a result of using cemented rockfill, rock mass stability is provided, a considerable part of industrial waste is disposed of in the mined-out area, and the earth’s surface subsidence within the area is prevented (in comparison with mining enterprises in other fields).

Abstract:

Goa is one of the most famous international tourist destinations of the world. Export of Iron ore extracted from the midland of Goa is a major economic activity. However, there is a serious concern of air pollution due to iron ore mining activities. In order to assess the impact of mining activities on the environmental regime, the air quality depreciation index was adopted for this study due to its realistic and meaningful presentation of deterioration in ambient air quality. The index had been applied to the ambient air quality monitoring results of thirty four locations in the iron ore mining region of Goa. To envisage upon the deterioration in air quality due to various activities, eight stations were selected around mines, twelve in the buffer zone (within 4 Km radius of the core mining activities) and fourteen along the ore transportation routes for monitoring of SPM, PM10, SO2 and NOX. The deterioration of air quality in the iron ore mining region of Goa is clearly apparent as the depreciation in air quality was found < -1 from the most desired value of 0 at all the stations. In general, the air quality was found most depreciated along the ore transportation routes, which is also evidenced by a considerable load of particulate matters observed. This infers that ore transportation is the most devastating activity in the iron ore mining region of Goa and accordingly mitigation plan should be adopted.

Abstract:

Since the Gol-Gohar iron ore mine (GGIOM), which is located in southeastern Iran, is currently one of the biggest iron mines in this region, increasing the accuracy of its mineral resources model has become a challenge for geologists, metallurgists and mining engineers. Given that an accurate classification of the mining blocks into ore or waste is highly significant in strategic mine planning, three approaches for simulating the iron grades were compared against the true grades obtained from production data. The comparison was done by calculating the ratio between the total number of blocks correctly classified as ore and waste and the total number of misclassified blocks, and it was conducted for each approach in three mined benches at the GGIOM. The results reveal that the grade simulation that ignores the geological boundaries and the grade simulation based on a deterministic geological interpretation are much less accurate than the hierarchical approach, which consists of simulating both the geological boundaries and the grades.

Abstract:

The phosphorus content has significant effect on the steels quality and their applications. The iron ore resources around the world has continuously increased the amount of phosphorous due to the increase of the mining volume with less sterile generation aiming at the efficient utilization of the mining resources, as consequence larger amount of materials with high iron content but with higher phosphorous has been incorporated in the mining body. An alternative to enhance the mining efficiency is to perform a pre treatment of part of the mining body and subsequent blending to attain the acceptable phosphorous in the steelmaking. A viable alternative for reducing the phosphorus content of these residue is to use the acid leaching process which is considered an economical process for the dephosphorization of the iron ore, however, depending on the way the element phosphorus is contained in the ore it will demand additional energy. The objective of the present paper is to study the effective heating and cooling rates of iron ore using microwave energy and its subsequent cooling effect in a short period (thermal shock). Through the X-ray diffraction analysis and applying the Rietveld method it has been possible to demonstrate the mineralogical composition of the iron ore samples and the effect of rapid heating and cooling suitable to promote the fissure formation, thus enhancing the leaching efficiency. The scanning electron microscopy (SEM) was used to analyze the structure of ore due to the effect of its heating and cooling rates.

Abstract:

The latest information on geological and structural position and geological structure of deposits of rich iron ores of the Belozerskyi iron ore district is summarized, and the state of their industrial development is characterized. During the exploitation of the Pivdenno-Bilozirske and Pereverzivske deposits, due to geological study, mining exploration and additional exploration of deep horizons, specialized and feasibility study a significant amount of new geological data has been received. This data allowed to clarify the position, morphology and internal structure of ore bodies, qualitative, physical and mechanical properties of ores and enclosing rocks, hydrogeological, geological, engineering and mining conditions. The article presents the results of the analysis and interpretation of the latest geological information and actual data on the mine development of deposits – modern views on the geological structure of objects, the characteristics of the basic natural conditions and parameters that affect the efficiency of industrial mining of rich iron ores. The state of geological prospecting in the region is very uneven. The most studied are the Pivdenno-Bilozirska and Pereverzivska fields, which are currently being developed. The rich iron ores of these deposits are classified as high quality in both Ukraine and Europe. These ores do not require beneficiation and are suitable for agglomeration and open-hearth process. This circumstance helps to reduce the cost of mining and increase the commercial efficiency. For the mine development of both deposits, a common infrastructure is used – permanent mine openings, mine shafts, support facilities and services. Joint development of the deposits will ensure the long-term stable operation of the plant without reducing the production of rich iron ores. The deposits are characterized by difficult mining and technical operating conditions. The ore deposits are covered by a cover up to 250–350 meters of loose water-saturated sedimentary deposits. The iron ore strata and the host rocks have heterogeneous physical and mechanical properties. Iron ores are mined using a productive level-room system. Empty rooms are filled consolidating stowing. The advanced drainage and continuous groundwater withdrawal from mines are used in the mining process. The progressive system of iron ores mining ensures: preservation of the productivity and quality of aquifers, which are used for municipal water supply; preservation of the earth’s surface from avalanches and landslides in the mining area; stable environmental conditions at the plant area and in the surrounding area; efficiency and completeness of extraction of iron ores from the bowels; the optimal level of economic indicators of the enterprise.

Abstract:

For the purpose to solve the problem of reducing the negative impact of mining and processing production on the environment that is relevant for most mining regions of Russia, options of geotechnological strategy for mining of iron ore deposits on the basis of an ecologically balanced integrated underground geotechnology of extraction and processing of iron ore, which allow to utilize the entire volume of mining and processing waste in the mined out space and transfer the most environmentally hazardous enrichment process under the ground, have been formed. Technological schemes for chamber excavation of floors in ascending order have been developed, which make it possible to abandon the formation of ore pillars, thereby increasing the extraction of ore from the bowels, and using the worked out space for waste storage in the form of a dry backfill. Based on economic and mathematical modeling and a comprehensive assessment according to the environmental and economic criterion for the conditions of mining in a new step of one of the largest iron ore deposits in Russia the most effective option of geotechnical strategy has been established. Use of an ascending-descending order of floor mining with an optimal ratio of mining systems with laying out the worked out space and systems with collapse depending on the content of the useful component in the ore mined, the amount of space mined current tab and the volume of tailings used as backfill material, allows to utilize the entire volume of mining and processing waste in the mined out space and effectively to develop of reserves in a new step.

Abstract:

Introduction. The current negative trends in the decline of the working-age population, as well as changes in the pension legislation, raise the issue of preserving the labor potential and health of the population more sharply than ever. The aim of study is to assess the occupational health risk of employees in iron ore mining with the subsequent development of management measures. Materials and methods. Jobs of priority professions were selected: creeper, sinker, GROZ, scraper winch and drilling rig drivers. The assessment of working conditions and occupational risk was carried out in accordance with guidelines R 2.2.2006-05 and R 2.2.1766-03 on the basis of materials provided by the company, as well as its own measurement results using available predictive models for assessing occupational health risk of employees. Results. The results of the study indicate that there is a high (intolerable) occupational health risk in all professions, category of evidence 1A. Aerosols, industrial noise, vibration, and heavy labor remain the leading health risk factors. The average length of professional pathology development, depending on the nosological form, was in the range of 20-30 years. Conclusions. Based on the results of the work, recommendations were given for managing occupational health risks.

Abstract:

Iron and Steels is one of the top three major imports of Nepal. Based on the fact that Nepal has large amount of mineral resources, it is important to explore and exploit them rationally. This research paper is carried out to estimate the iron ore reserve of the iron ore deposits of Pokhari in Nawalparasi which was recently discovered by Department of Mines and Geology (DMG), Nepal. In this research work, the technical and financial assessment of hematite (iron ore) extraction of iron deposits of Pokhari, taking an area of one square kilo meter, has been carried out. The tonnage of iron ore and the overburden (which is quartzite and slate in this case) were estimated considering the mining process to be open cast mining using vertical cross-section method. The depth of hematite zone is taken as 100 m. The iron ore to over-burden (waste) ratio was 1:3.36. The financial analysis was done on the basis of extraction of 3600 metric tons of iron ore per day and 8,64,000 metric tons annually. The return on investment (ROI) is 34%. Thus, the research work indicates that the extraction of large amount of iron ore of Pokhari area is economical and it is a beneficial project.

Abstract:

This paper studies the production and distribution planning problem faced by the iron ore mining companies, which aims to minimize the total costs for the whole production and distribution system of the iron ore concentrate. The ores are first mined from multiple ore locations, and then sent to the corresponding dressing plant to produce ore concentrate, which will be sent to distribution centers and finally fulfill the customers' demands. This paper also tackles the difficulty of variable cut-off grade when making mining production planning decisions. A mixed-integer programming model is developed and then solved by a Lagrange relaxation (LR) procedure. Computational results indicate that the proposed solution method is more efficient than the standard solution software CPLEX.

Abstract:

One of the most critical factors affecting iron pellet quality is the reduction in FeO (Iron Oxide) index in the final product. This study aims to predict factors affecting the FeO (Iron Oxide) of iron pellets and find out the contribution of each factor to reduce the pellets FeO (the ideal amount is between 0.4 to 0.6) using data mining techniques. When the FeO index's value is in the optimal range, the quality and price of pellets are higher. The data used in this study was collected from the pelletizing plant of Gol-E-Gohar in Sirjan, Iran, and the decision tree and regression algorithms are used in this analysis. Forty-five factors that can affect the FeO (Iron Oxide) index of the final product were studied, showing that the Magnesium Oxide and Airflow of the inlet fan of the indurating machine had the greatest impact on the FeO (Iron Oxide) of iron pellets.

Abstract:

Reconciliation of geological, mining and mineral processing information is a costly and time demanding procedure with high uncertainty due to incomplete information, especially during the early stages of a project, i.e., pre-feasibility, feasibility studies. Lack of information at those project stages can be overcome by applying synthetic data for investigating different scenarios. Generation of the synthetic data requires some minimum sparse knowledge already available from other parts of the mining value chain, i.e., geology, mining, mineral processing. The aim of the paper is to describe how to establish and construct a synthetic testing environment, or “synthetic ore body model” for data integration by using a synthetic deposit, mine production, constrained by a mine plan, and a simulated beneficiation process. The approach uses quantitative mineralogical data and liberation information for process simulation. The results of geological and process data integration are compared with the real case data of an apatite iron ore. The discussed approach allows for studying the implications in downstream processes caused by changes in upstream parts of the mining value chain. It also opens the possibility of optimising sampling campaigns by investigating different synthetic drilling scenarios including changes to the spacing between synthetic drill holes, composite length, drill hole orientation and assayed parameters. A synthetic deposit model can be a suitable tool for testing different scenarios for implementation of geometallurgical programs and also an educational tool for universities and companies.

Abstract:

Mining in general has become essential industry sector for the sustaining growth of any developing country. In India iron ore mining is mainly mechanised and well developed industry sector, using highly mechanised equipments and technology for excavation and processing of mined iron ore. It is due to this reason iron ore mining seen as a one of the major sector responsible for workplace occupational health hazard particularly for noise related health impacts on workers health. The objective of this study was to ascertain the job specific noise exposure among the Similar Exposure Groups (SEGs). Total 133 personal noise dosimeter samples were collected from different job category and working areas of iron ore mining and processing sector. It was observed that the participated workers in the crushing area were exposed to 81.64 dB (A), Heavy Earth Moving Machineries (HEMM) operators 86.10 dB (A), loading plant workers 83.76 dB (A), screening plant workers 87.62 dB (A) and mines operation and workshop workers 84.92 dB (A). During the study specifically HEMM operators were highly exposed to workplace noise, with 46% samples exceeding warning limit and 18% exceeding danger limit prescribed by Directorate General of Mines Safety (DGMS), Government of India. It was felt necessary to augment the awareness and safety training to the workers for proper implementation of preventive measure for workplace noise exposure.

Abstract:

A new mining scheme by employing the induced caving mining method to exploit hanging-wall ore-body during the transition from open pit to underground mining is proposed. The basic idea is to use the mined-out area generated by the planned mining of the hanging-wall ore-body to absorb the collapsed slope body, so as to avoid the influence of the inner-slope mining to the normal open-pit mining and guarantee mining efficiency during the transition stage. Numerical simulation study on the process of induced caving mining of hanging-wall ore-body is carried out based on the practical engineering setting of the Hainan iron mine, China, by employing the numerical method of discontinuous deformation analysis (DDA). The impact of rock mass structure on the mechanism of slope instability development and the mining hazard assessment in the new mining scheme is investigated. The influence of mining sequence on slope instability development and mining safety is also analyzed by taking the hanging-wall ore-body mining under the southern anti-dip slope at the Hainan iron mine as an example, and eventually a reliable mining scheme via induced caving is obtained. The numerical study proves the feasibility of the proposed new mining scheme for hanging-wall ore-body and provides theoretical and technical support for its application in practical mining activities.

Abstract:

The mineral composition and magnetic behavior of nano-Fe2O3 of iron ore from Lhoong mining area, Aceh province, were studied. The iron ore was prepared by mechanical milling method. The mineral and chemical compositions of samples were investigated by XRD and XRF analysis tests. The XRF test showed that the Lhoong iron ore contains Fe2O3 (93.88%) in association with other isomorphous impurities, such as SiO2, MnO, and Al2O3, in varying proportions. Compared to XRD results, it was consistent with XRF; the phase compositions of iron ore were mainly hematite (Fe2O3). The XRD revealed that hematite was the major mineral component in the Lhoong iron ores. SEM observation showed fine crystalline structure of Lhoong iron ore after the milling process. The main mineral morphology was microcrystalline in agglomerate forms. The magnetic properties of the samples after milling showed the increasing in the remanent (Br) and coercivity (Hc). This increasing can be explained that nano-Fe2O3 phase after milling for 20 hours plays an important role in the magnetic behavior of Lhoong iron ore. It is understood that the longer milling time is sufficient to complete the transformation of hematite (Fe2O3) to magnetite (Fe3O4).

Analysis of literature sources, project documentation and practical data that contain information on the current state and conditions for the development of iron ore in Ukraine, as well as data on varieties and state of reserves of different types of these ores. Findings. The problem, faced by domestic iron ore mining enterprises in connection with reaching the large depths of mining operations and the emergence of a shortage of raw material resources, is described. The volumes of magnetite quartzites, which are contained in the dormant mines, operating mines, and those mines of Ukraine that are not currently in operation, are determined. The expediency and directions for resuming the development of these ores, as well as expanding the raw material base of the domestic iron ore mining industry, are justified. Originalty. The principal approaches to the implementation at a modern technological and technical level of the cyclic-flow underground mining technology for the development of magnetite quartzite reserves, which is capable of ensuring the economic efficiency of their extraction at depths where the open method of their development becomes unprofitable, are expanded. Practical value. Ensuring the economic efficiency of underground development of magnetite quartzite reserves in operating conditions of the iron ore mining enterprises of Ukraine leads to a significant expansion of their raw material base, which is currently constantly decreasing, as well as support of the production capacity of these enterprises for a long period of time, and allows Ukraine to remain one of the leaders in the iron ore mining industry in the world. Key words: prospects, underground mining, magnetite quartzites, mining, technological, economic aspects.

Abstract:

The impact of former iron ore mining on the transformation of vegetation cover of the Gielniowski Hump (Małopolska Upland) The impact of the 17th-19th century iron ore mining on the current state of vegetation cover of the Gielniowski Hump, an upland region situated within the Old Polish Industrial Region (a former centre of mining and smelting), was studied. In the course of the research, the detailed floristic lists were compiled using the cartogram method (ATPOL grid) and phytosociological relevés were made according to the Braun-Blanquet method. Relevés were taken both at the post-mining sites (on spoil banks) and, for comparative purposes, in the adjacent, not affected areas. The obtained results show significant differences between the flora and vegetation of the sites affected and unaffected by mining. These differences result from the changed mineralogical composition of soil in the post-mining areas, which has lead to an increase in the proportion of mesophilous forest communities and in the number of species of the class Querco-Fagetea as compared to the unaffected sites. Overall, the former iron ore mining activity has increased the biodiversity level in the Gielniowski Hump mesoregion due to an increase in the total number of species in the area, brought about by the formation of a mining-related habitat mosaic.
