Wireless Communication in Underground Mines: RFID-based Sensor Networking

Wireless communication has emerged as an independent discipline in the past decades. Everything from cellular voice telephony to wireless data transmission using wireless sensor networks has profoundly impacted the safety, production, and productivity of industries and our lifestyle as well. After a decade of exponential growth, the wireless industry is one of the largest industries in the world. Therefore, it would be an injustice if the wireless communication is not explored for mining industry. Underground mines, which are characterized by their tough working conditions and hazardous environments, require fool-proof mine-wide communication systems for smooth functioning of mine workings and ensuring better safety. Proper and re- able communication systems not only save the machine breakdown time but also help in immediate passing of messages from the vicinity of underground working area to the surface for day-to-day normal mining operations as well as for speedy rescue operations in case of disaster. Therefore, a reliable and effective commu- cation system is an essential requisite for safe working, and maintaining requisite production and productivity of underground mines. Most of the existing systems generally available in underground mines are based on line (wired) communication principle, hence these are unable to withstand in the disaster conditions and dif?cult to deploy in inaccessible places. Therefore, wireless communication is an indispe- able, reliable, and convenient system and essential in case of day-to-day normal duty or disaster situations.

International Seminar on Design Methods in Underground Mining 2015

International Seminar on Design Methods in Underground Mining 2015

The Australian Center for Geomechanics will host the inaugural International Seminar on Design Methods in Underground Mining in Perth in 2015. This seminar will focus on both the numerical and empirical methods used for the design of underground metalliferous mines.

A variety of underground mining methods and designs are used to extract various ore bodies from the large and massive, to the narrow tabular, flat or steeply-dipping, in competent or weak rock masses. Some design techniques, in particular the empirical approaches, which are very useful during feasibility studies, are often specific to the mining method – whether it is a caving, an open stope mining or cut-and-fill method. Achieving a robust design at this stage is critical to ensure that the mine’s initial extraction progresses without major problems.

Once ore extraction is underway, more data becomes available and there is then an opportunity to calibrate numerical models and optimize the main mine design parameters. The International Seminar on Design Methods in Underground Mining will have a special focus on case studies where design methods have been successfully applied.

Technical challenges

Technical developments in the understanding of the rock mass and fill behavior, in conjunction with dilution measuring techniques, improved blasting, equipment, ventilation and ground support practices, currently permit the successful application of underground mining methods in increasingly complex geological and mining situations, even at great depth. In particular, an increased understanding of the design methods is required to optimize extraction sequences, leading to full orebody recovery while achieving dilution control.

Who should attend?

This exciting seminar is aimed at mine operators, geologists, surveyors and mining engineers wishing to understand and explore the full mine planning and design process; including the geotechnical implications from data collection to back analysis of stope performance.

Seminar themes:

•          Open stope and bench mine design
•          Narrow vein mine design
•          Cut-and-fill/undercut-and-fill design
•          Empirical design
•          Dilution control
•          Numerical modelling
•          Rock mass classification
•          Stress measurements
•          Modelling of geomechanical data
•          Monitoring
•          Design methods for seismically active mines
•          Drill and blasting
•          Planning and scheduling

Keynote speakers:

•          Dr Will Bawden, CEO of Mine Design Engineering, Canada
•          Professor Emeritus Rimas Pakalnis, Pakalnis & Associates, and the University of British Columbia, Canada
•         John Player, MineGeoTech, Australia
•         Emiritus Professor Dick Stacey, Professor of Rock Engineering, University of the Witwatersrand, South Africa

Engineering Geology for Underground Rocks - S. Peng, J. Zhang

Engineering geology for underground rocks is a sub-discipline of engineering geology for describing and solving geological engineering problems encountered in underground mining, petroleum and civil engineering. It covers rock mechanics for underground rocks, rock hydraulics, wellbore mechanics, mine geology and mine hydrogeology.

This book clearly and systematically explains underground engineering geology principles, methods, theories and case studies, depicts engineering problems in underground rock engineering and how to study and solve them. It specially emphasizes mechanical and hydraulic couplings in rock engineering for wellbore stability, mining near aquifers and other underground structures where inflow is a problem. Using the methods and models given in this book, the reader is able to analyse underground geological engineering problems and also for the design of underground structures.

Professionals and students in engineering geology, geological, mining, petroleum, civil engineering, rock mechanics, and mine geology will find this an essential reference.

Engineering Rock Mechanics Part II: Illustrative Worked Examples can be used as an independent book or alternatively it complements an earlier publication called Engineering Rock Mechanics: An Introduction to the Principles by the same authors. 
It contains illustrative worked examples of engineering rock mechanics in action as the subject applies to civil, mining, petroleum and environmental engineering. The book covers the necessary understanding and the key techniques supporting the rock engineering design of structural foundations, dams, rock slopes, wellbores, tunnels, caverns, hydroelectric schemes and mines. There is a question and worked answer presentation with the question and answer sets collated into twenty chapters which match the subject matter of the first book.

Rock Mechanics for Underground Mining , 3rd Edition - B.H.G. Brady and E.T. Brown

Based on extensive professional, research and teaching experience, this book will provide an authoritative and comprehensive text for final year undergraduates and commencing postgraduate students. For professional practitioners, not only will it be of interest to mining and geological engineers but also to civil engineers, structural and mining geologists and geophysicists as a standard work for professional reference purposes.
