This book was released on with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methodology: The project utilized down-the-hole (DTH) drilling techniques due to the steep slopes and limited access to machinery. Blast designs were customized to ensure stability while avoiding excessive disturbance to the surrounding environment. A combination of emulsion and water-gel explosives was used to ensure safety and effectiveness in the challenging conditions. Challenges: One of the most prominent challenges was the unpredictability of rock conditions, which necessitated ongoing assessments and adjustments to the drilling and blasting parameters. Furthermore, the environmental protocol required strict adherence to minimize impact on local fauna and flora. Results: The successful completion of the pipeline installation not only fulfilled the project timeline but also maintained compliance with environmental standards. This case underscores the necessity of adaptive management strategies in drilling and blasting, particularly in sensitive environments where both safety and ecological considerations are paramount.

Density The density of soil and rock materials is essential in understanding their load-bearing capabilities. Bulk density is defined as the mass of the soil or rock per unit volume, which includes both the solid particles and the void spaces between them. Specific gravity, on the other hand, is a measure of density relative to the density of water and reflects the inherent material properties. The relationship between moisture content and density is particularly significant. As water content increases, the density of the material changes, impacting its engineering behavior. Saturated soils will exhibit different properties compared to dry soils, highlighting the importance of considering environmental conditions in classification. 3. Moisture Content Moisture content is the amount of water contained in the soil or rock, expressed as a percentage of the dry mass. It is a critical factor influencing the behavior of both soils and rocks. In soils, moisture affects weight, cohesion, and plasticity. The Atterberg limits, critical for classifying fine-grained soils, define the boundaries of moisture content for various states: liquid, plastic, and shrinkage. In rocks, moisture plays a vital role in weathering processes and can impact the rock’s strength and durability. Saturated conditions may lead to changes in pore pressure, potentially causing instability, especially in cases where excavation or grading is being performed.

Available in PDF, EPUB and Kindle. Book excerpt: This annual series of books includes scientific papers on mining profiles. This volume presents multiple aspects of mining technology implementation in several aspects: extraction of coal, iron, manganese, uranium and other ores. Capturing and utilization of coalbed methane by various methods including alternative ones, safety measures in mining, ecological aspects, etc.Specific attention is paid to intensification of mineral resources extraction processes by way of modernizing opening methods, development and mining methods depending on mining-geological conditions. Experimental results of stress-strain state rock massif forecast by means of computational experiments using recursive methods are also discussed. Any mining operations should finally result in adequate recovery of land surface and utilization of mining wastes using various environmentally friendly methods, thus, sufficient attention is paid to this scientific trend. Non-traditional methods of minerals mining are becoming more topical and of higher demand in the modern society. Hence, several papers/chapters are devoted to underground coal gasification and its subsequent processes. In addition, extraction technologies of gas hydrate, as a source of an abundant amount of natural gas, are thoroughly examined in this book, including implementation of gas hydrate technologies for mine methane utilizations with its following transportation in a solid state. Furthermore, attention is given to evaluation of economic efficiency of minerals mining by the proposed methods, their ways of enrichment, ecological aspects and the influence of mining production on the environment, innovational logistic solutions at mining enterprises, and also to perspectives of Ukraine‘s mining industry integration to the European standards.

Book excerpt: The conferences on ‘Applications for Computers and Operations Research in the Minerals Industry’ (APCOM) initially focused on the optimization of geostatistics and resource estimation. Several standard methods used in these fields were presented in the early days of APCOM. While geostatistics remains an important part, information technology has emerged, and nowadays APCOM not only focuses on geostatistics and resource estimation, but has broadened its horizon to Information and Communication Technology (ICT) in the mineral industry. Mining Goes Digital is a collection of 90 high quality, peer reviewed papers covering recent ICT-related developments in: - Geostatistics and Resource Estimation - Mine Planning - Scheduling and Dispatch - Mine Safety and Mine Operation - Internet of Things, Robotics - Emerging Technologies - Synergies from other industries - General aspects of Digital Transformation in Mining Mining Goes Digital will be of interest to professionals and academics involved or interested in the above-mentioned areas.
