This part is part 17 of GB/T 9649, instead of GB/T 9649.17-2001 "Geology and Mineral Terminology Classification Code Coal Science ".

This section compares with GB/T 9649.17-2001, the main changes are as follows.

- Standardized language, choreography and format according to GB/T 1.1-2000;

--- added some new terms;

- a partial explanation of the improper explanation;

- Fixed part of the term;

--- Fixed the English translation of the existence of the problem.

Appendix A of this section is a normative appendix.

This part is proposed and centralized by China Standardization Research Institute.

1 Scope

This part of the provisions of the coal, coal, coal metamorphism, coal pellet analysis, coal resources exploration, coal, coal, industrial analysis, coal Gasification and liquefaction, coal and rock composition classification and the physical properties of coal and other coal geology data classification code.

This part applies to all kinds of geological and mineral information system construction, is to determine the database standard system and data dictionary, the development of various types of geological data Standard format for file format standards.

2 Terms and definitions

The following terms and definitions apply to this section.

2.2 Qualitative description

A qualitative description of the basic attributes of a geological entity.

3 Classification principle

3.1 This part of the principle of easy to use and minimize the code redundancy and the lack of room for expansion and other principles, the use of surface classification, the geological science Divided into 35 categories of disciplines, and strictly divide the border, to maintain the overall system, integrity, to avoid duplication of content and cross.

3.2 categories below the use of three tree classification, in class, small class to the basic data item name. Discipline content level, can be less than three, in the Encoding capacity allows the conditions can also be divided into four layers.

3.3 Classification at all levels is scientific, systematic and versatile.

4 Principle of choice

4.1 Selection of words. may be used as a database of various types of geological and mineral data items (including from the classification of the selected data items on the concept of the upper)

And the terminology used to qualitatively describe the text values of the data item. The selected terminology is consistent with the current national standards According to the current variety of geological work norms.

4.2 The term used as a data item is unique in this section. Where there are synonyms in the remarks column marked for reference.

4.3 words to seek simple, clear, no ambiguity. Taking full account of the need to build a database.

4.4 To ensure that the "geological mineral terminology classification code" is holistic, systematic, to avoid duplication, in the basic disciplines already included in the content, applied Science is no longer selected, emerging disciplines and marginal disciplines only selected its unique content. See Appendix A for a description of the attribution of categories.

4.5 Appropriate selection of some new disciplines to reflect the new direction, the new level of terminology.

4.6 In order to facilitate the use of individual high frequency of data items in different disciplines can be repeated, but to use a unified code to ensure that the code Uniqueness. Text values in different data items can be repeated in small amounts.

5 Encoding method

5.1 data items with no more than six Latin alphabet (uppercase) coding, generally divided into four levels. Structure is as follows;
