GB/T 15663.10-2008Terms relating to coal mining - Part 10: Winning machinery and developing machinery (English PDF)

Foreword

GB/T 15663 Terms relating to coal mining is divided into the following parts: Part 1 Coal geology and exploration; Part 2 Shaft and roadway engineering; Part 3 Underground mining; Part 4 Surface mining; Part 5 Hoisting and transport; Part 6 Mine surveying; Part 7 Mining subsidence and special mining methods; Part 8 Coal mine safety; Part 10 Winning machinery and developing machinery; Part 11 Coal mine electrical engineering.

This part is Part 10 of GB/T 15663.

This part replaces GB/T 15663.10-1995 Terms relating to coal mining - Winning machinery and developing machinery.

Compared with GB/T 15663.10-1995, the main changes are as follows: the Chinese names of a number of terms were revised; the English equivalents of a number of terms were revised; the definitions of a number of terms were revised; the definition of the name of one term was revised; a substantial number of new terms were added; and a number of terms were deleted. The foreword lists, entry by entry, the clause numbers concerned in the 1995 edition and in the present edition.

This part was proposed by the China National Coal Association.

This part is under the jurisdiction of the National Technical Committee on Coal of Standardization Administration of China.

The drafting organizations of this part are the Shanghai Branch, the Taiyuan Research Institute and the Mine Construction Branch of the China Coal Research Institute, the Mining Design and Research Branch of the China Coal Research Institute, and Kaisheng Heavy Industry Co. Ltd.

The previous edition of the standard replaced by this part was GB/T 15663.10-1995.

1 Scope

The vocabulary of coal winning and roadway development machinery, fixed as a Chinese national standard. A longwall face is described by half a dozen trades at once - the machine builder, the mine planner, the maintenance shift, the safety inspector and the standards writer - and each of them arrived with its own words for the same thing. The same drum is a cutting drum in one document and a coal drum in another; haulage means the chain that pulls the shearer in one shop and the drive that moves it in the next. A terminology standard settles this by naming one preferred term for each concept, listing the synonyms that are still met in the literature, marking the ones that are now deprecated, giving the definition in Chinese and the English equivalent, so that a specification, a purchase order and an accident report can be read against each other. This part of GB/T 15663 fixes the general terms and the terms for coal winning machinery, for developing machinery and for hydraulic supports, and it applies to all documents, standards, codes, specifications, books, textbooks and manuals concerned with winning and developing machinery and hydraulic supports. It closes with a Chinese pinyin index and an English index, so that a term can be found from either language. The 2008 edition revised a long list of Chinese terms, English equivalents and definitions taken from the 1995 edition, added a substantial number of new terms and deleted terms that had fallen out of use. Its users are equipment manufacturers, mine engineering departments, translators and the drafters of the mining standards that cite it.

This part of GB/T 15663 specifies the general terms and the terms for coal winning machinery, developing machinery and hydraulic supports.

This part applies to all documents, standards, codes, specifications, books, textbooks and manuals relating to winning and developing machinery and to hydraulic supports.
