8、d Kingdom. Although the majority of the terms defined in the original edition of this glossary 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 u

9、sed within the industry, and the prevalent use of more than one synonym, some purely 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: Borin

10、g and exploration; Section4: Drainage; Section5: Geology; Section6: Drilling and blasting; 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 rev

11、iew of the BS3618 publications it was seen that a number of modifications were desirable to Section7, “Electrical engineering and lighting”; therefore, since the initial edition was dated1965, it was decided to publish a revision incorporating these changes. In compiling the glossary account has bee

12、n taken of the fact that terms primarily associated with coal are separately defined in 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 an

13、d definition of terms: 1) Where two or more terms are grouped together, the term which 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 smaller type. Where the use

14、of any term is considered to be undesirable it is marked deprecated. 2) Generally, 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 p

15、articular importance in mining. 3) Purely local terms are not defined, but those of sufficient importance are included as non-preferred terms. 4) Obsolete terms are excluded.BS3618-7:1973 BSI 12-1999 iii A British Standard does not purport to include all the necessary provisions of a contract.
