7、 been prepared, under the authority of the Mining and Quarrying Requisites Industry Standards Committee, in order to standardize and to co-ordinate the technical terms in current use in mining in the United Kingdom. Although the majority of the terms defined in the original edition of this glossary
8、were primarily concerned with coal mining, account has been taken of terms used in other forms of mining and of quarrying. The need for this glossary arose from the widely varying interpretation of terms used within the industry, and the prevalent use of more than one synonym, some purely local in o
9、rigin, to indicate specific meanings. The glossary has been issued in a number of sections, according to subject matter, as follows: Section1: Planning and surveying; Section2: Ventilation; Section3: Boring and exploration; Section4: Drainage; Section5: Geology; Section6: Drilling and blasting; Sect
10、ion7: Electrical engineering and lighting; Section8: Winning and working; Section9: Shafts and associated equipment; Section10: Transport; Section11: Strata control. Section3, “Boring and exploration”, was one of the early publications in the BS3618 series. In the normal process of periodical review
11、 it was seen that certain amendments were desirable; therefore, since the previous edition was dated1963, it was decided to publish a revision incorporating these changes. In compiling the glossary account has been taken of the fact that terms primarily associated with coal are separately defined in
12、 BS3323, “Glossary of coal terms”, and terms relating to coal preparation are defined in BS3552, “Glossary of terms used in coal preparation”. The following factors also have applied in the statement, selection and definition of terms: 1) Where two or more terms are grouped together, the term which
13、is favoured is printed first and in heavy type. It is hoped that such preferred terms will gradually displace the non-preferred terms. The non-preferred terms of a group are printed in small capital letters. Where the use of any term is considered to be undesirable it is marked deprecated. 2) Genera
14、lly, only terms which have a specific meaning in this field have been included. Where a technical term has an accepted meaning in other fields of engineering it has been omitted; the few exceptions are terms which are of particular importance in mining. 3) Purely local terms are not defined, but tho
15、se of sufficient importance are included as non-preferred terms. 4) Obsolete terms are excluded. The subject of soil mechanics is not covered by this standard and, for terms in that field, reference should be made to CP2001, “Site investigations”, and CP2003, “Earthworks”.BS3618-3:1971 BSI 11-1999 i
