    1、BRITISH STANDARD BS3618-4: 1971 Glossary of Mining terms Section 4: DrainageBS3618-4:1971 This BritishStandard, having been approved by the Mining andQuarrying Requisites Industry Standards Committee, was published under the authorityof the Executive Boardon 18February1971 BSI12-1999 First published

    2、 May1963 First revision February1971 The following BSI references relate to the work on this standard: Committee reference MQE/17 Draft for approval69/21050 ISBN 580 06108 6 Co-operating organizations The Mining and Quarrying Requisites Industry Standards Committee, under whose supervision this Brit

    6、ersity of Birmingham University of London University of Nottingham Amendments issued since publication Amd. No. Date CommentsBS3618-4:1971 BSI 12-1999 i Contents Page Co-operating organizations Inside front cover Foreword ii Glossary 1BS3618-4:1971 ii BSI 12-1999 Foreword This glossary has been prep

    7、ared, 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 this glossary were primar

    8、ily 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 origin, to i

    9、ndicate 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; Section7: Elect

    10、rical 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 additions were desirable to

    11、Section4, “Drainage”; 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 BS3323, “Glossary of coal term

    12、s”, 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 is favoured is printed first an

    13、d 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 which have a sp

    14、ecific 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 importance are

    15、 included as non-preferred terms. 4) Obsolete terms are excluded. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity

    16、 from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1 to5 and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside
