Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on rock slope stability in open pit mines, this book provides an up-to-date compendium of knowledge of the slope design processes that should be followed and the tools that are available to aid slope design practitioners. This book links innovative mining geomechanics research into the strength of closely jointed rock masses with the most recent advances in numerical modelling, creating more effective ways for predicting rock slope stability and reliability in open pit mines. It sets out the key elements of slope design, the required levels of effort and the acceptance criteria that are needed to satisfy best practice with respect to pit slope investigation, design, implementation and performance monitoring. Guidelines for Open Pit Slope Design comprises 14 chapters that directly follow the life of mine sequence from project commencement through to closure. It includes: information on gathering all of the field data that is required to create a 3D model of the geotechnical conditions at a mine site; how data is collated and used to design the walls of the open pit; how the design is implemented; up-to-date procedures for wall control and performance assessment, including limits blasting, scaling, slope support and slope monitoring; and how formal risk management procedures can be applied to each stage of the process. This book will assist in meeting stakeholder requirements for pit slopes that are stable, in regards to safety, ore recovery and financial return, for the required life of the mine.

Using energy consumption information, different sustainability issues can be addressed, such as the relationship with ore grade over the years, energy variations in electricity or fossil fuel use. A rigorous analysis and understanding of the energy intensity use in mining is the first step towards a more sustainable mining industry and, globally, better resource management. Numerous studies have focused on the energy consumption of mining projects, with analysis carried out primarily in one single country or one single region. This paper quantifies, on a global level, the relationship between ore grade and energy intensity. With the case of copper, the study has shown that the average copper ore grade is decreasing over time, while the energy consumption and the total material production in the mine increases. Analyzing only copper mines, the average ore grade has decreased approximately by 25% in just ten years. In that same period, the total energy consumption has increased at a higher rate than production (46% energy increase over 30% production increase).

However, the possible hazard of waste and radioactivity generated by mining, dumping and tailing, has called on the society to find ways of seeking remedy that will adequately treat mining waste from mine dump, tailing and abandoned mine. Mine waste reuse and recycling in mining industries could offer cost-effective benefits through offsetting raw material requirements and decreasing the volumes of waste to be managed. This review discussed mine dump pollution monitoring and mine dump management strategies for some selected countries. Impact and mechanism of mine damage to the environment was discussed together with the remediation principles. It further examines the mining Act and regulations of the same selected countries. Emphasised was placed on the enforcement of environmental laws, regulations, and standards. Practical ways in which country's state authority and civil society can keep a close watch and enhance the enforcement of laws and regulations were highlighted. The prediction for the control of mineral exploration and environmental assessment was also discussed for executing a specific control to take preventive measures. Management techniques used in combating the impact of mine dump, stockpiles and tailing on the environment were discussed. In addition, radioactivity in mine and its monitoring and control was discussed.

The technological process of producing silicate aggregates begins with the unloading of mined material, where the pieces of stone are crushed primarily, secondarily and tertiaryly, and then separated. Production lines … The technological process of producing silicate aggregates begins with the unloading of mined material, where the pieces of stone are crushed primarily, secondarily and tertiaryly, and then separated. Production lines at the crushing and separation plant can be adjusted to some extent to market demand. Recently, there has been a high demand for skeletal mastic asphalt SMA 11, which has a distinctly skeletal structure compared to the previously demanded asphalt concretes. This demand somewhat disrupts manufacturers' production lines. The need for the 8/11 mm fraction has increased compared to the others. As a result, stockpiles of other fractions are accumulating at the separation plants, with an emphasis on the 4/8 mm fraction. This imbalance makes it challenging to manage non-renewable mineral resources effectively, leading to a negative environmental impact. The paper presents the problems producers face and provides possible solutions for utilising such deposited material. Additionally, the need for intervention by state institutions was emphasised when it comes to solutions regarding the use of other asphalt mixtures, which are already widely used worldwide.

The main idea … This article is devoted to the study of the possibilities for improvAzing the quality of energy management systems adopted at open-pit mining enterprises in the Russian Federation. The main idea of the work is to apply stochastic boundary value analysis methods using the production function for individual and integral estimates of the performance of energy-consuming objects when performing various types of technological work. It is shown that mining enterprises are experiencing problems in the field of rational energy consumption due to the lack of strictly formalized ways to determine the frontiers of the efficiency value of the parameter of specific energy consumption (SEC). A justification is given for the need to apply stochastic frontier analysis (SFA) methods and use the Cobb–Douglas production function to account for the nonlinearity and stochasticity of the operating conditions of energy-consuming mining objects. The results of a statistical analysis of the data on the operation of EKG-10 excavators at operating enterprises in Siberia are presented, as well as an assessment of their energy efficiency using the adopted approach based on planning the target value of SEC. The results of computational experiments on constructing an energy efficiency model using the SFA/Cobb–Douglas function for various data segmentation options are presented. Computational experiments have been conducted to compare variants based on the Cobb–Douglas production function and translog function with semi-normal and exponential distribution forms for the same data set. A comparative assessment is given of the approaches to the complex analysis of activities adopted at enterprises and proposed in this study, characterizing potential hidden energy losses in the range from 4.53% to 20.73%.

However, their structural integrity is highly dependent on a foundation … Overland Conveyors (OLC) are widely recognized as a reliable and energy-efficient solution for bulk material transport in modern mining operations. However, their structural integrity is highly dependent on a foundation system capable of safely resisting axial, tensile, and lateral loads—especially when constructed across diverse and challenging subsoil conditions. This study presents a geotechnical-based analytical approach to estimate the single-pile capacity of bored and driven piles along the proposed OLC alignment in East Kalimantan, Indonesia. Subsurface investigations from 23 boreholes, comprising SPT and CPT data, were used to evaluate bearing capacity for pile diameters ranging from 0.3 to 1.0 meters and depths up to 50 meters. Load demands were assumed based on preliminary structural considerations: 2000 kN axial load and 280 kN lateral load per foundation unit. The analysis incorporates empirical methods for axial and uplift capacity, adjusted for dominant soil types, while lateral capacity was assessed using Broms’ method. Results are visualized through a set of design-friendly graphs, enabling rapid configuration assessment (single or grouped piles) without the need for finalized structural loads. These graphs serve as a practical tool for early-stage design exploration, helping engineers balance safety, constructability, and cost. Ultimately, this research offers not only a systematic method for selecting efficient pile configurations under variable geotechnical profiles, but also reinforces the importance of field data-driven foundation planning for resilient and cost-effective OLC infrastructure.

Road … Resource depletion and environmental degradation have resulted from the substantial increase in the use of natural aggregates and construction materials brought on by the growing demand for infrastructure development. Road building using mining waste has become a viable substitute that reduces the buildup of industrial waste while providing ecological and economic advantages. In order to assess the appropriateness of several mining waste materials for use in road building, this study investigates their engineering characteristics. These materials include slag, fly ash, tailings, waste rock, and overburden. To ensure long-term performance in pavement applications, this study evaluates their tensile and compressive strength, resistance to abrasion, durability under freeze–thaw cycles, and chemical stability. This review highlights the potential of mining waste materials as sustainable alternatives in road construction. Waste rock and slag exhibit excellent mechanical strength and durability, making them suitable for high-traffic pavements. Although fly ash and tailings require stabilization, their pozzolanic properties enhance subgrade reinforcement and soil stabilization. Properly processed overburden materials are viable for subbase and embankment applications. By promoting the reuse of mining waste, this study supports landfill reduction, carbon emission mitigation, and circular economy principles. Overall, mining byproducts present a cost-effective and environmentally responsible alternative to conventional construction materials. To support broader implementation, further efforts are needed to improve stabilization techniques, monitor long-term field performance, and establish effective policy frameworks.

This study investigated the concentrations … Artisanal and small- scale mining (ASM) activities are prevalent in many part of Nigeria and have been linked to significant environmental and public health concern. This study investigated the concentrations of heavy metals and the associated physicochemical properties of soil collected from an artisanal mining site in Rimin Zayam Toro Local Government Area of Bauchi State Nigeria. To assess the extended of environmental contamination and provide baseline data for environmental monitoring and remediation efforts. Soil samples were obtained from three different sites namely; abandoned mining site, active mining site and non - mining site respectively. The heavy metals concentrations were determined and quantified for Cd., Cr, Cu, Fe, Mn, Ni, Pb and Zn using Atomic Absorption Spectroscopy (AAS). Physicochemical properties such as the pH, total organic carbon, total organic matter, electrical conductivity and soil particle size were analyzed using standard methods. The soil examined under the following abandon, active and non-mining sites. From the results soils pH reveals slightly alkaline in nature for all mining sitesi.eabandon, active and non-mining site having 6.04, 6.45 and 6.35 respectively; with moderate electrical conductivity of 31.30, 42.66 and 26.75 (µS/cm) respectively; low to medium value of total organic carbon of 0.062, 0.423 and 0.452 (%); medium to high total organic matter value of 0.844, 0.729 and 0.780 (%) and ECEC values are 7.385, 4.003 and 3.994 for abandon active and non-mining sites respectively. All the values were lower than the maximum allowable concentrations in soils for mining sites. Although appreciable amounts of all the metals were detected in the various site but were within the permissible limit (WHO /FAO). Cd, Cu and Pb were below detectable limits in the three sites. The findings indicate the absence of environmental contamination from heavy metals and physicochemical properties due to early stage mining activities have not yet significantly impacted the surrounding environment. This is a wakeup call for a proactive environmental management. The current baseline data can serve as an essential environmental changes and guiding regulatory oversight in artisanal mining operations.
