Mechanical Excavation in Mining anAutor: Bilgin,Nuh,Copur,Hanifi,Balci,Cemald Civil Industries


The secret to streamlined scheduling of mining and civil engineering projects is a solid understanding of the basic concepts of rock cutting mechanics. Comparing theoretical values with experimental and real-world results, Mechanical Excavation in Mining and Civil Industries thoroughly explains various rock cutting theories developed for chisel, conical, disc, and button cutters. The authors provide numerical examples on the effect of independent variables on dependent variables, as well as numerical and solved examples from real-life mining and civil engineering projects using equipment such as:
    Hard- and soft-ground tunnel boring machines (TBMs)
    Roadheaders
    Shearers
    Ploughs
    Chain saws
    Raise borers
    Impact hammers
    Large-diameter drill rigs
    Microtunnel boring machines
This book assists students and practicing engineers in selecting the most appropriate machinery for a specific job and predicting machine performance to ensure efficient extraction, and offers background information on rock cutting mechanics and different mechanical miners.

SURFACE AND UNDERGROUND EXCAVATIONS

SURFACE AND UNDERGROUND EXCAVATIONS
Methods, Techniques and Equipment
Ratan Raj Tatiya

Excavation is a multi-disciplinary activity in the areas of civil, construction and mining engineering. The excavation industry is booming because of the yearly creation of thousands of kilometers of tunnels, many mine openings and millions of cubic meters of large underground excavations for transportation, mineral mining, oil and gas storage, hydroelectric power station construction, defense facilities and for the disposal of hazardous waste.
Surface and Underground Excavations – Methods, Techniques and Equipment provides a comprehensive text on the latest technologies and developments in excavation for any type of surface or underground excavation. In the first few chapters, unit operations are covered, including drilling, explosives and blasting, mucking, haulage, hoisting, supports and reinforcement. Subsequently, excavation techniques are described for various operations, like tunneling, raising, sinking, drifting, stoping, quarrying and surface-mining, underground mining, pillar blasting and liquidation. In addition, the design, planning and development of excavations are treated in a separate chapter. Special attention is paid to the construction of surface and subsurface excavations, including caverns and to new methodologies to select stoping methods through incremental analysis. For practical illustration, the final chapter contains case studies dealing with heavy underground blasting during pillar recoveries.
This expanded second edition has been wholly revised, removing obsolete information and including latest trends and best practices as well as questions at the end of each chapter. It is now fully up-to-date and even more appealing to students and those with a general or professional interest in surface and underground excavations. As such, this book is particularly suited to students in earth sciences, geology and in civil, mining and construction engineering.

OPEN PIT MINE PLANNING & DESIGN

OPEN PIT MINE PLANNING & DESIGN
William A. Hustrulid, Mark Kuchta, Randall K. Martin

Open Pit Mine Planning and Design is an outstanding textbook designed for courses in surface mine design, open pit design, geological excavation engineering, and advanced open pit mine planning and design. The step-by-step introduction to mine design and planning enables a fast-track approach to the matter by undergraduate and graduate students. The excellent, user-friendly software guides the student through the planning and design steps, and the drillhole data sets allow the student to practice the described principles in various mining properties case examples. The large number of illustrative examples and case studies, together with the exercises and the reference lists at the end of each chapter, provide the student with all the material needed to study effectively the theory and application methods of open pit mine planning and design.
Volume One: Fundamentals covers the fundamental concepts involved in the planning and design of open pit mines. Subjects covered include mine planning, mining revenues and costs, orebody description, geometrical considerations, pit limits, production planning, mineral resources and ore reserves, responsible mining, blasting, drilling, loading, hauling and equipment availability, and utilization.
Volume Two: CSMine Software Package deals with CSMine, a user-friendly mine planning and design software that was developed specifically to illustrate the principles involved when applied in practice. It includes CSMine software, a CSMine tutorial, MicroModel user's guide and tutorial and various orebody case examples.
Although intended as student course material, many practitioners have used it as a practical reference guide. This third edition has been wholly revised, updated, and significantly expanded.
