Balkema in 1998 and further embraces terminologies from closely related technolo- gies encountered in Mining and Construction Technology. This makes it today a complete Encyclopaedia in Mining and Rock Construction Technology. Effort has also been directed at including common terms not defined in other dictionaries. Terms from related disciplines commonly used in Mining and Rock Construction litera- ture include chemistry, detonics, fractography, fracture dynamics, mechanics and strength of materials, micro mechanics, geology, geophysics, image analysis, petrology, physics seis- mology etc. Rock types are, however, not included since this would extend the size of the Encyclopaedia too much. The Encyclopaedia aims to enable newcomers and workers in these fields to commu- nicate and learn effectively by standardising the language of these disciplines. As in Rock Blasting Terms and Symbols, it presents not only short definitions of the terms, but also quantifies them and defines their relationship to other parameters. All scientists, engineers, technicians, teachers, practitioners and students working and learning in Mining and Rock Construction Technology should find it indispensable for communicating, reading, writing and teaching through scientific papers, technical reports, etc. These categories will also be better acquainted with symbols, acronyms, abbreviations, shortened forms and units and this knowledge will assist them in publishing in their fields. The Encyclopaedia will therefore be important for the ‘Science and Practical work in Mining and Rock Construction Technology’. The Chairman, Agne Rustan of the Working Group on Terminology belonging to the Fragblast Section at Society of Explosives Engineers (ISEE) formed an International Group, in collaboration with the ISEE Fragblast Section Chairman William Fourney. The group consisted mainly of the following members from the ISEE Fragblast Section; William Four- ney USA, Claude Cunningham South Africa and Alex Spathis Australia. To this group joined later on Prof K.R.Y. Simha India and Prof Lusk USA. Min Eng Walter Harr, a former specialist at Sandvik AB in Sweden, was engaged to check the additional drilling terms. Ulf Linder Atlas Copco AB Sweden, kindly supplied the Terminology Group with an extensive drilling dictionary, from which several terms were taken. To cover the field of Rock Mechanics, Prof John Hudson UK was engaged to check most of the new such terms added to the First Edition. 77000077TTSS--RRUUSSTTAANN00--BBooookk..iinnddbb iixx 1100//2200//22001100 1100::0099::2222 AAMM x Introduction A useful source vocabulary list was the historic ‘USBM ‘Dictionary of Mining, Mineral and Related Terms’ which contains about 55 000 terms and includes approximately 150 000 definitions (because one term can have several definitions). In current literature, short and often incomplete glossaries or dictionaries relevant to Mining and Rock Construction Tech- nology were found. The most extensive dictionaries in blasting were developed by Atlas Powder, USA (365 terms) and the Institute of Makers of Explosives, USA (293 terms). 109 Rock Mechanics terms not defined in the above mentioned sources were taken form the Five volumes “Comprehensive Rock Engineering. Principles, Practice & Projects”, edited by John Hudson. The present Encyclopaedia contains 5127 terms and, 637 symbols, 507 references, 236 acronyms, 108 formulas, 68 figures, 47 tables, 58 abbreviations and 7 shortened forms. The Encyclopaedia of Mining and Rock Construction Technology is arranged for maxi- mum cross-referencing and ease of use. Its features include: • The use of the standard symbols that will make it much easier to read and understand formulas. Each formula must, however, always be followed by an explanation of the symbols and the units being used when used in papers. • When a term is shown in the Encyclopaedia, the symbol will be found after the entry of the term together with its recommended unit and with the most common used prefix for the unit. When synonym terms are presented the same information is given. • When synonyms exist, the entry of the recommended synonym is given in bold and the other not recommended in italics. • Short histories of explosives and initiation equipment are given under the term History of explosives and History of initiation. Methods to measure fragmentation are system- ized and important parameters for fragmentation are highlighted etc. • Two separate symbol lists are given, one with Arabic symbols and another with Greek symbols. • By indexing the symbols many different parameters, like different burden distances, can be defined more precisely using distinct symbols. In the course of the compilation of this Encyclopaedia, four terms were identified that lack international standards for descriptive and or operational definitions. 1 Diggability 2 Friction sensitivity of explosive materials 3 Shape of a particle or fragment 4 Storage of explosives I would like to express my sincere thanks to all the colleagues mentioned in the preface for volunteering in this extensive work on the extension of the ‘Terminology Book in Rock blast- ing’ to an ‘Encyclopaedia of Mining and Rock Construction Technology’.

Agne Rustan Editor-in-Chief Note: Mining technology is improving fast and new terms are constantly being developed and used. Therefore, it will be necessary to upgrade this Encyclopaedia at regular intervals and your comments are therefore very much appreciated.
