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.

SISTEMAS FLEXIBLES DE ALTA RESISTENCIA EN LA ESTABILIZACION DE TALUDES

SISTEMAS FLEXIBLES DE ALTA RESISTENCIA EN LA ESTABILIZACION DE TALUDES
Revision de los metodos de diseño existentes y propuesta de una nueva
metodogia de dimensionamiento
Elena Blanco Fernandez

Los sistemas flexibles de alta resistencia anclados al terreno son una de las distintas técnicas existentes para la estabilización de taludes, ya sean de roca o de suelo. Están constituidos por una membrana (red de cables o malla de alambre) sujeta al terreno mediante placas de anclaje, cables de refuerzo y bulones. Se estima que alrededor de 1.000.000 de m2 son instalados cada año en todo el mundo. Actualmente no existen guías técnicas de carácter oficial que definan de forma rigurosa el comportamiento de estos sistemas, su procedimiento de cálculo y su modo de instalación. Son generalmente los mismos fabricantes los que desarrollan sus propias guías internas de diseño e instalación. La motivación de este trabajo radica precisamente en esta carencia de normativa técnica objetiva con un adecuado rigor científico. El presente trabajo recoge de forma íntegra la tesis doctoral defendida por la autora el 6 de mayo de 2011 en la Universidad de Cantabria. Su director de tesis, Daniel Castro Fresno, es Profesor Titular en la E.T.S.I. Caminos, Canales y Puertos de la Universidad de Cantabria. Posee 42 artículos científicos indexados, 12 patentes y más de 60 contribuciones a congresos

GEOMECHANICAL PROCESSES DURING UNDERGROUND MINING

Volodymyr Bondarenko, Iryna Kovalevska,Mykhaylo Iliiashov,Genadiy Pivnyak

This volume deals with economic aspects of mining companies’ development strategies, various mineral deposits development techniques, imitational modeling of mine workings with rock massif, methane extraction technologies during coal mining, geomechanical processes during plow mining, mining transport importance for mineral extraction, massif strain-stress state management using non-explosive destructing materials, and surface mining's detrimental influence on the environment.
Special attention is paid to alternative ways of mining, such as borehole underground coal gasification for extraction of hardly accessible coal and development of gasification plant and development and use of alternative sources of energy such as gas hydrates and sun energy are also disucssed in this book.
This collection of scientific papers will be of interest to mining engineers, engineering technicians, designers, scientific and research personnel, students, postgraduates, and all mining-related professionals working in the coal and ore industry.

ADVANCES IN UNSATURATED SOILS

ADVANCES IN UNSATURATED SOILS

Berardo Caicedo,Carol Murillo,Laureano Hoyos,Julio Esteban Colmenares

New theories and testing techniques related with Unsaturated Soil Mechanics have proven to be valuable tools to study a broad spectrum of geo-materials which includes rocks, rock fills, frozen soils and domiciliary solid wastes. These new theories and testing techniques have permitted the analysis of several traditional problems from a new perspective (e.g., swelling or collapsible soils and compacted soils or pavements materials), and they have also shown their efficiency to study new energy-related problems like CO2 sequestration and nuclear waste disposal.
Advances in Unsaturated Soils is a collection of papers from the 1st Pan-American Conference on Unsaturated Soils organized in Cartagena de Indias, Colombia, in February 2013. The volume includes 76 research papers coming for all over the world, as well as 7 keynotes papers by well known international researchers. The contributions present a variety of topics including:
• Advances in testing techniques
• Unsaturated soil behavior
• Constitutive modeling and microstructure
• Numerical modeling
• Geotechnical problemsAdvances in Unsaturated Soils
is expected to become a useful reference to academics and professionals involved in Unsaturated Soil Mechanics.
