The purpose of writing this book is to provide the latest research findings in ground control techniques in mining engineering, especially the rock bolting techniques. Since rock bolts are widely used in mining engineering and civil engineering, they are significant in guaranteeing the safety of underground openings. However, instability issues still occur with the rock bolting technique. Therefore, it is valuable to understand the exact load transfer mechanism of rock bolts. This book summarised the recent research work regarding rock bolting conducted by the authors. It is valuable for the readers to fully understand the reinforcing mechanism of fully grouted rock bolts. This book focuses on the bond failure mode of fully grouted rock bolts, which is the most widely encountered failure mode in rock bolting. Different investigation approaches are used in this book, including numerical simulation, analytical modelling and experimental tests. Therefore, this book conducts a comprehensive study to reveal the bond failure process of fully grouted rock bolts. Moreover, it reveals the corresponding bond failure mechanism. Therefore, it helps the reads to fully understand the bond failure mechanism of rock bolting. Moreover, it helps the readers to develop new approaches and methods to prevent failure of the rock bolting system. This is an open access book.

This book focuses on the unified solutions and analysis for the problems in soil mechanics based on the unified strength theory, which is a new theory on the yield and failure of materials under multi-axial stresses. Then, it provides a system of yield and failure criteria adopted for most materials, from metallic materials to rocks, concretes, soils, polymers, etc. It includes the Tresca criterion, Mohr–Coulomb theory, and Mises criterion as well, which are special cases or linear approximation of the UST. .

The industrial acceleration intensifies the negative environmental impacts, mainly in some very sensitive geographical areas. Environmental problems like water stress, deadly floods, scarcity of building materials, and prolonged periods of drought affect southern countries, including African nations. This book comprises the peer-reviewed proceedings of the fourth scientific conference on geosciences and environmental management (GeoME'4), held in Salé, Morocco, on June 22–24, 2023. The book interests all researchers, practitioners, and students in geosciences, the environment, and water management. The book delivers a comprehensive overview of the latest research covering the following aspects of green technologies for sustainable water and wastewater management: nature-based solutions in the water cycle and advanced technologies in geosciences, geotechnics, and the environment. Additionally, it features six keynote speakers by international experts, providing valuable insights and further enhancing its value as a comprehensive resource on the following topics: Water management Environmental engineering Geosciences and geotechnical engineering.

Increased environmental and energy concerns have renewed global interest in raw earth as a building material. Low-energy requirements, low-cost, high availability at construction sites, and favorable engineering properties make (EBMs) an attractive alternative to conventional cement-based construction materials. Though the use of native binders to improve soil properties has garnered attention in recent literature, the available knowledge has not been covered in a single document. This book highlights the key soil properties that determine the mechanical performance of earthen building materials, importance of unsaturated soil mechanics in the engineering behavior of earthen building materials, the different types of stabilizers used to improve the engineering performance of earthen building materials including the use of select native binders, the characteristics of compressed earth blocks stabilized with cement and cement + wood ash additives and the improvement in the engineering properties of adobes stabilized with plant fibers and cow dung. .

The book develops a practical understanding of the fundamental scientific principles and logic underlying the art of turf pitch preparation, measuring, analysing, and interpreting pitch surface behaviour. It’s an attempt to understand how the captains, players, coaches, curators, and groundsmen comprehend and analyse the cricket pitch behaviour (days before and during the matches) and whether the pitch behaviour can be standardised and quantified (through bench marking or forming a data-based management system (DBMS) of a pitch profile, pitch quality standards, a pitch behaviour analysis index (PBAI), or pitch behaviour forecasting (PBF) by examining or analysing its mineralogical, chemical, physical, or morphological compositions, weather variables, and different pitch preparation methods and techniques. Individual chapters in this book deal with clay mineralogy, the bench-marking of cricket pitch soils, pitch soil chemical properties, pitch soil water, pitch turf grass, pitch soil organic matter, integrated rolling management, soil structure, and compressibility. This is an effort to decipher the impact of each and every major and minor component of pitch soil, which controls the pitch behaviour either in large or small magnitudes but acts as a critical factor in defining and shaping the pitch behaviour as a whole. Several real-life examples, pitch interviews, scenarios, and case studies as felt and observed by the curator( first author) during the preparation of various international, national, and board matches or during the construction and renovation of new wickets have been included in each and every relevant chapter so as to analyse, interpret, comprehend, and justify the theoretical science with the existing practises involved in pitch construction, preparation, or judging the complex nature of pitch behaviour. Based on findings through the DBMS, PBAI, and PQS of cricket pitch profiles, various innovative and simple methods of analysing, comprehending, and forecasting pitch behaviour have been devised that will enable one to judge and comprehend the complex pitch behaviour in simple ways.

Climate protection and raw material change require new, sustainable carbon sources for the chemical and fuel industries. In fact, processes that recycle carbon-containing emission and gas streams industrially are reaching industrial practice. They will make an important contribution to reducing carbon emissions and moving towards a true carbon circular economy. This book describes the basics of chemical and biotechnological processes for converting CO and CO2 into chemicals and fuels. Furthermore, it addresses potentials for the manufacturing economy, industrial sites and regions and answers the following questions. Which emission and gas streams offer feedstock potential? What processes are already implemented, being tested and under development? What products can be made from gaseous carbon sources? How can carbon emitting and consuming industries be linked into new value chains? What is the regulatory framework? What does the ecological footprint look like? How do the new processes contribute to the regional economy and thus to social acceptance among consumers and among decision-makers in companies and politics? Providing companies with sustainable carbon sources is a central question of the circular economy, which must be answered with technical processes, new cross-sector value chains, adapted infrastructure and further developed framework conditions. This concerns scientists and decision-makers in companies alike. In this book, they as well as interested laymen will find a comprehensive overview of the state of the art in both, technology and research, and of the overriding issues involved in establishing CO2 and CO as feedstocks.
