2. 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.

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.

The secret to streamlined project scheduling is a solid understanding of basic rock cutting mechanics. Comparing theoretical values with experimental and real-world results, Mechanical Excavation in Mining and Civil Industries explains rock cutting theories for chisel, conical, disc, and button cutters. The authors provide numerical examples on the effect of independent variables on dependent variables, as well as examples from real-life mining and civil engineering jobs. The book assists students and engineers in machinery selection and performance prediction, and discusses rock cutting mechanics and mechanical miners.

This book gathers technical and scientific articles by leading experts from 15 countries and originally presented at the world’s most prestigious forum on coal preparation: the XVIII International Coal Preparation Congress. Topics addressed include: the mineral resources basis of the coal industry; problems and prospects of development in the coal industry; crushing, grinding, screening and classification processes used at sorting plants; coal processing and briquette factories; review of plant designs and operations used around the world; new developments in dense-medium separators, water-based separation processes, froth flotation and dewatering; technologies and equipment for the dry separation of coal; coal deep processing technologies and equipment; energy generation as an area of coal deep processing; and simulation and optimization software for separation processes.In general, the future of coal around the world is defined by its competitiveness. As the cheapestform of fuel (comparatively speaking), coal undoubtedly continues to be in high demand around the world.
