8、glossary has 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 UnitedKingdom. Although the majority of the terms defined in the original edition of thi

9、s glossary were primarily concerned with coalmining, 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

10、local in origin, 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 blas

11、ting; Section7: Electrical engineering and lighting; Section8: Winning and working; Section9: Shafts and associated equipment; Section10: Transport; Section11: Strata control. In the normal process of periodical review of the BS3618 publications it was seen that a number of modifications and additio

12、ns were desirable to Section5, “Geology”; therefore, since the edition was dated1964, 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 BS3323, “Glossary o

13、f coal terms”, and terms relating to coal preparation are defined in BS3553, “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 is favoured is print

14、ed 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) Generally, only terms whic

15、h 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 those of sufficient imp

16、ortance are included as non-preferred terms. 4) Obsolete terms are excluded.BS3618-5:1971 BSI 11-1999 iii A British Standard does not purport to include all the necessary provisions of a contract.
