In surface mines, various activities (e.g., excavations, loading and unloading of material, moving vehicles on unpaved haul roads, etc.) represent significant sources of fugitive dust. The estimation of dust generation from each individual source is a basic step in planning and implementation decision-making systems regarding the air quality of the surrounding area. Typically, this can be obtained by using emission factor or prediction-type equations. A detailed study was carried out at four surface lignite mines to determine PM emission factors and to develop the prediction-type equations of various surface mining activities. In this work, the data, method and results referring to the stacker, one of and the significant fugitive dust emissions source in mining operations are presented and analyzed.

The article addresses the issues of ensuring safe operation of mining equipment in surface mining. It describes the main factors and situations that pose a high risk to human life and health. The most dangerous incidents are shown to be related to limited visibility and blind spots for operators of mining equipment, which can result in collisions and personnel run over. The main technologies and specific solutions used to design collision avoidance systems are described and their general comparison is provided. A particular focus is placed on monitoring the health of employees at their workplace by means of portable personal devices that promptly inform the dispatcher of emergency situations. General technical requirements are formulated for designing of the system to prevent equipment collisions and personnel run over in surface mining operations. The paper emphasizes the importance of introducing a multifunctional safety system in surface mines in order to minimise the possibility of incidents and accidents throughout the entire production cycle.

The study investigated the environmental effects of quarry operations in Abeokuta, Ogun state, while it specifically sought to identify corresponding environmental impacts posed in quarry operation and, assess the efforts towards minimizing environmental impacts of their operations. Primary data used for this study was obtained from 100 residents of the community and staffs of the company, randomly chosen and administered with structured questionnaires. Ninety one percent of the respondents noted that environmental problems like land degradation and pollution (including air, water and noise pollution) are associated with mining activities in their respective communities. Air pollution and noise pollution were found to have significant (p < 0.05). Long period (58.0%) of surface mining (71.7%) is prominent in the study area, while it posed some hazards to residents in the study area (84.0%). This includes (degradation of land and vegetation (72.0%), water pollution (44.0%), air pollution (44.0%) and noise pollution (56.0%). Noise and air pollution and governmental intervention in environmental degradation of Mining were found to have significant (p < 0.05) impact on host community as identified by staff of mine and residents. Efforts towards minimizing environmental impacts of quarrying include resettlement and compensation of affected communities (20%). Environmental effects such as land degradation and pollution of various forms (air, ground vibration and noise) in the surrounding communities where the mining activities (quarry operations) are carried out are associated with surface mining activities. It is therefore recommended that government agencies overseeing mining operations revise environmental management policy to ensure that the environmental effects of mining activities are reduced to the barest minimum.

Mining activities are usually associated with environmental impacts, particularly that of air pollution by fugitive dust. Malmberget mine is one of the most important iron mines in Sweden and the dust problem has been noticed by the inhabitants for a long time. Dust collectors had been installed to measure the dust fallout around the mining site. In this research the dust fallout recorded during the period August 2006 till July 2010 were analyzed. Generally speaking the amount of dust fallout was decreasing year by year due to some implemented dust control methods. Mining activities produced more dust during summer than winter. The peak value was 265g/100m2/30d appeared in May 2007, and the lowest dust fallout was 25g/100m2/30d happened in August 2009. Dust was determined to be originated from the open pit area and the industrial center area. Truck transportation on the haul roads, wind erosion of stockpiles and exposed areas were the main activities that caused dust generation.

Selection Of

Selection and assessment of mining equipment used in open pit rock mines relies chiefly on estimates of overall exploitation cost. The rational arrangement of mining equipment and systems comprising loading machines, haul trucks and crushing plants should be preceded by a thorough analysis of technical and economic aspects, such as investment outlays and the costs of further exploitation, which largely determine the costs of mining operations and the deposit value. Additionally, the operational parameters of the mining equipment ought to be considered. In this study, a universal set of evaluation criteria has been developed, and an evaluation method has been applied for the selection of surface mining equipment and the processing system to be operated in specific mining conditions, defined by the user. The objective of this study is to develop and apply the new methodology of multi-criteria selection of open pit rock mining equipment based on multiple criteria decision-making (MCDM) procedures, to enable the optimization of loading, handling and crushing processes. The methodology, underpinned by the principles of MCDM, provides the dedicated ranking procedures, including the ELECTRE III. The applied methodology allows the alternative options (variants) to be ranked accordingly. Ultimately, a more universal methodology is developed, applicable in other surface mines where geological and mining conditions are similar. It may prove particularly useful in selection and performance assessment of mining equipment and process line configurations in mining of low-quality rock deposits. Therefore, we undertook to develop universal criteria and applications for the selection and performance assessment of process machines for surface mines, taking into account environmental aspects as well as deposit quality.

Abstract Forests, the backbone of biogeochemical cycles and life supporting systems, are under severe pressure due to varied anthropogenic activities. Mining activities are one among the major reasons for forest destruction questioning the survivability and sustainability of flora and fauna existing in that area. Thus, monitoring and managing the impact of mining activities on natural resources at regular intervals is necessary to check the status of their depleted conditions, and to take up restoration and conservative measurements. Geospatial technology provides means to identify the impact of different mining operations on forest ecosystems and helps in proposing initiatives for safeguarding the forest environment. In this context, the present study highlights the problems related to mining in forest ecosystems and elucidates how geospatial technology can be employed at various stages of mining activities to achieve a sustainable forest ecosystem. The study collates information from various sources and highlights the role of geospatial technology in mining industries and reclamation process.

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.

Prospecting and exploiting natural mineral resources for economic growth and development could be beneficial if done in sustainable ways and manners. However, if the operation is done in such a way that cause harm to the environment and people, this will amount to unsustainable mining activity and anti-sustainable development. Therefore, there is need to ensure that appropriate and adequate plans and programmes are put in place in order to mitigate, minimise and avoid negative environmental impacts. Against the backdrop of these concerns and the need to ensure that the environment is not degraded and destroyed, South Africa, as part of the countries that promotes sustainable prospecting and mining has put in place and currently implementing tools known as environmental management plan and programme to regulate and control all prospecting and mining activities. These tools contain a bundle of remedial actions in the forms of compensation, rehabilitation and restoration of any harm done to the environment during the course of mining activities. They also contain information on mitigation, ingredients for good practice approach on how to conduct sustainable prospecting and mining. This article looks at the intrinsic roles of these tools and accentuates the importance and operations of their use in the decision making processes.
