Industrial Explosives and their Applications for Rock Excavation focuses on applications of industrial explosives in civil and mining engineering works. Explosives and their actions are explained in terms of basics, principles, and related chemistry. Explosives and initiation devices are described, including their characteristics, geometry, and timing aspects of the blast design. Designing blasts for rock excavation works is explained, including devices for obtaining large-sized blocks, construction of yards, and excavation of big foundations. Finally, criteria for the mitigation of the associated seismic disturbances are summarized. The book: provides an updated vision of industrial explosives, including the best technical advice for rock excavation; contains harmonized preliminary modules aimed at introducing basic concepts of chemistry and physics applied to the drilling and blasting technique; defines balanced mix of theory capable of providing skills to design an efficient blasting; covers excavation problems from different points of view and in different contexts; and addresses issues of drilling and loading blast-holes.

“Everything” sums up what must be considered for a properly documented property evaluation. Less than 30% of the projects that are developed in the minerals industry yield the return on investment that was projected from the project feasibility studies. The tools described in this handbook will greatly improve the probability of meeting your projections and minimizing project execution capital cost blowout that has become so prevalent in this industry in recent years. Mineral Property Evaluation provides guidelines to follow in performing mineral property feasibility and evaluation studies and due diligence, and in preparing proper documents for bankable presentations. It highlights the need for a consistent, systematic methodology in performing evaluation and feasibility work. The objective of a feasibility and evaluation study should be to assess the value of the undeveloped or developed mineral property and to convey these findings to the company that is considering applying technical and physical changes to bring the property into production of a mineral product. The analysis needs to determine the net present worth returned to the company for investing in these changes and to reach that decision point as early as possible and with the least amount of money spent on the evaluation study. All resources are not reserves, nor are all minerals an ore. The successful conclusion of any property evaluation depends on the development, work, and conclusions of the project team. The handbook has a diverse audience: • Professionals in the minerals industry that perform mineral property evaluations. • Companies that have mineral properties and perform mineral property feasibility studies and evaluations or are buying properties based on property evaluation. • Financial institutions, both domestic and overseas, that finance or raise capital for the minerals industry. • Consulting firms and architectural and engineering contractors that utilize mineral property feasibility studies and need standards to follow. • And probably the most important, the mining and geological engineering students and geology and economic geology students that need to learn the standards that they should follow throughout their careers.

Surface and Underground Excavations – Methods, Techniques and Equipment (2nd edition) covers the latest technologies and developments in the excavation arena at any locale: surface or underground. In the first few chapters, unit operations are discussed and subsequently, excavation techniques are described for various operations: tunnelling, drifting, raising, sinking, stoping, quarrying, surface mining, liquidation and mass blasting as well as construction of large subsurface excavations such as caverns and underground chambers. The design, planning and development of excavations are treated in a separate chapter. Especially featured are methodologies to select stoping methods through incremental analysis. Furthermore, this edition encompasses comprehensive sections on mining at ‘ultra depths’, mining difficult deposits using non-conventional technologies, mineral inventory evaluation (ore – reserves estimation) and mine closure. Concerns over Occupational Health and Safety (OHS), environment and loss prevention, and sustainable development are also addressed in advocating a solution to succeed within a scenario of global competition and recession. This expanded second edition has been wholly revised, brought fully up-to-date and includes (wherever feasible) the latest trends and best practices, case studies, global surveys and toolkits as well as questions at the end of each chapter. This volume will now be even more appealing to students in earth sciences, geology, and in civil, mining and construction engineering, to practicing engineers and professionals in these disciplines as well as to all with a general or professional interest in surface and underground excavations.

Forensic Investigation of Clandestine Laboratories, Second Edition is fully updated to address all aspects of the forensic investigation of clandestine laboratories. While, the first edition focused on the domestic clandestine manufacture of contraband substances, this edition expands the scope to more fully address the clandestine manufacture of explosives that have become a threat that is global in nature. In clandestine laboratory operations, equipment is often simple, household chemical products are utilized, and the education of the operators basic. In fact, most of the time these elements individually are perfectly legal to sell and possess. However, the combination of all these elements is what becomes the scene of illicit activity and a criminal operation. In response to the increase in use of homemade explosive mixtures by terrorists, both domestically and internationally, the section clandestine manufacture of explosives is greatly enhanced. Topics are presented in a manner which, while detailed, will not compromise the tactics, techniques, or procedures utilized by law enforcement and military personnel in their ability to combat the clandestine manufacture of contraband substances and the battle against domestic and international terrorism. Key features: • Examines tell-tale signs to look for in recognizing a clandestine lab • Outlines how to safely process the site of a clandestine lab • Details how to analyze collected evidence in the examination laboratory • Provides guidelines as to what to derive from the physical evidence • Offers specific tactics to effectively present the opinions associated with evidence that has been collected during the investigation in a written report, military style briefing or to a jury in a legal proceeding. Forensic Investigation of Clandestine Laboratories, Second Edition guides the reader through the process of recognizing these illegal manufacturing operations. Then it examines the methods as to how to compile the volume of associated evidence into a package that can be presented in a court of law, or to military commanders for decisive action. It is an invaluable resource, that will prove useful to chemistry lab technicians, forensic investigators, fire and first responder professionals, military personnel, police investigative agencies and narcotics units, and lawyer trying cases involving clandestine labs.
