GB/T9649.17—2001
Informatization in the field of geology and mineral resources has emerged in countries around the world. my country should catch up with the world's advanced level, introduce modern information technology, and develop my country's information resources to ensure the realization of information sharing between various information systems to be built. In 1985, the national standardization department approved the establishment of the project to formulate the national standard "Geological and Mineral Terminology Classification Code", which was approved and issued in 1988. The content of GB/T9649-1988 "Geological and Mineral Terminology Classification Code" is mainly the terms used to collect the attributes involved in various types of relevant information and the text values ​​used to qualitatively describe the attribute characteristics in combination with various geological phenomena in geological and mineral production and scientific research. In order to facilitate application and division of labor in compilation, and avoid duplication and omission of content, subject classification is used for compilation. After consultation, appropriate division of labor is made for the overlapping parts of the content between subjects to ensure the overall systematicity, integrity and uniqueness. Character codes are given to terms used as data items (attributes), and a coding scheme combining surface classification and line classification is adopted, which can maintain uniqueness and have sufficient room for expansion. There will be no duplicate codes when supplemented as needed by the application. Terms used as text values ​​are generally coded with numbers, which is conducive to storage and retrieval, saving space and improving processing speed.
After five years of application, GB/T9649-1988 was revised in 1993 according to user requirements. Due to actual needs, only some disciplines were revised this time, and a series of standards were adopted to facilitate user use and future revisions. In order to maintain the stability of the standard, the principle of this revision is to keep the overall structure, word selection scope, classification principles, word selection principles and coding methods unchanged, and the original term code remains unchanged as much as possible, and its content is appropriately supplemented and modified. The 17th discipline "Coal Geology" of GB/T9649-1988 "Geological and Mineral Terminology Classification Code" was drafted by Wu Chonglong, Huang Jiafu, Yang Shigong and others. This standard is a revision of the "coal geology" section of GB/T9649-1988 "Classification Code for Geological and Mineral Terms". The revision of this standard mainly includes four aspects:
1. According to the needs of the construction of information systems such as "Shuonan Coalfield Geological Exploration Database", "National Coal Resources Database", and "Coal Mine Geology Database", more than 400 new coal mining technical conditions and coal mine (well) design terms have been added. These terms mainly include coal seam mining and utilization conditions, such as coal seam roof and floor lithology and gas content, which provide a basis for the difficulty of coal seam mining and utilization and the prevention of coal spontaneous combustion and gas explosion, as well as mine construction scale, well type, mining method, mining authority and safe mining; 2. The general terminology symbols in coal petrology and coal chemistry of this standard are consistent with the relevant national standard symbols of "Compilation of Coal Standards and Instructions" compiled by the National Coal Standardization Technical Committee in 1997; 3. From the perspective of discipline integrity, new terms including sedimentary environment of coal-bearing rock series, structural geology, coal formation in coal accumulation basins, coal metamorphism, etc. have been added. 4. Added content related to coal mining and utilization, such as environmental geological disasters, wastewater, gas, pollution, management and utilization. This time, more than 930 terms were added and modified.
Appendix A of this standard is the appendix of the standard.
This standard was proposed by the Ministry of Land and Resources.
This standard is under the jurisdiction of the China Institute of Standardization and Information Classification and Coding. This standard was drafted by the China Institute of Geology and Mineral Resources Information. This standard was drafted by the China Institute of Geology and Mineral Resources Information. Responsible for management and maintenance. The main drafters of this standard are Chen Chunzai, Wu Chonglong, Wang Xinqing, Liao Yuzhi, Ma Deyao, Zhao Jingman, Fu Yikai, Hao Zhongyu. GB/T9649-1988 was issued on July 8, 1988. GB/T9649-1988 Part 17 was revised for the first time on April 29, 2001. I

The Terminology classification codes of geology and mineral resources-Coalgeology
GB/T9649.17—2001
Partially replaces GB/T9649—1988
This standard specifies the data items and text values ​​of the subject of "coal geology", including coal seams, coal accumulation, coal metamorphism, coal accumulation basin analysis; coal resource exploration related content, coalification, coal quality, industrial analysis, coal gasification and liquefaction; coal rock composition classification, coal physical properties and various classifications of coal.
This standard is applicable to the construction of various geological and mineral information systems, determines the database standard system and data dictionary, is the basic standard for formulating various geological data file format standards, and provides a technical basis for information exchange and sharing. 2 Definitions
This standard adopts the following definitions.
2.1 Data item: refers to the terminology that reflects the basic attributes of various geological entities and their upper-level concepts. 2.2 Text value: refers to the terminology used to make a specific qualitative description of the basic attributes of geological entities. 3 Classification principles
3.1 This standard adopts the surface classification method according to the principles of easy compilation and use and minimizing the code redundancy while leaving room for expansion, and divides geological science into 35 major disciplines, and strictly divides the boundaries to maintain the overall systematicity and integrity, and avoid duplication and overlap of content. 3.2 A three-level tree classification is adopted under the major categories, from medium categories, small categories to basic data item names. The content levels of each discipline are different, and can be less than three levels. Under the condition that the coding capacity allows, it can also be divided into four levels. 3.3 Classification at all levels is scientific, systematic and universal. 4 Selection principles
4.1 Objects of word selection: terms that may be used as data items of various geological and mineral databases (including the upper-level concepts of data items selected from the classification sense), as well as terms used to qualitatively describe the text values ​​of data items. The selected terms are consistent with the current relevant national standards, and try to refer to various current geological work specifications.
4.2 The terms used as data items are unique in this standard. All synonyms shall be marked in the remarks column for reference, but shall not be used when building the database.
4.3 The words shall be simple, clear and unambiguous. The needs of establishing the database shall be fully considered. 4.4 In order to ensure the integrity and systematicness of the "Classification Code of Geological and Mineral Terms" and avoid duplication, the content already included in the basic disciplines will no longer be selected in the applied disciplines, and only the unique content of emerging disciplines and marginal disciplines will be selected. For instructions on the scope of classification word selection, please see Appendix A. 4.5 Some terms that reflect the new direction and new level of discipline development shall be appropriately selected. 4.6 For the convenience of use, individual data items with high frequency of use may appear repeatedly in different disciplines, but they shall be encoded uniformly to ensure the uniqueness of the code. There may be a small amount of duplication of text values ​​under different data items. 5 Coding method
5.1 Data items are coded with no more than six Latin letters (uppercase), and are generally divided into four levels. The structure is as follows:XXX
Major category, middle category, and small category data item
Major categories use the Chinese phonetic initials of two Chinese characters that can reflect the meaning of the category as codes, which have a certain readability. For example, "structural geology" uses "GZ" as the code. The following is a tree-shaped nested format, with the middle category and small category each taking an alphabetical order from A to Z. The last two are basic data items, which are relatively large in number and are arranged in the order of AA to ZZ. If there is a need for grading and there is enough expansion margin, the last two digits can also be divided into two levels. bZxz.net
5.2 Text values ​​are generally coded digitally, and their length is determined by the needs of classification, the number of text values, and the margin for expansion. They should be shortened as much as possible to reduce the margin. When text values ​​are graded, digital hierarchical nesting is used, and the text value codes under the same data item are equal-length codes. Some text values ​​(such as chemical elements, strata, etc.) continue to use the original international or domestic universal character codes. 6 Use and Management
6.1 Usage: This standard is provided in both written and magnetic media forms. Users can select the required terms and their codes from various disciplines according to their respective database building purposes as the data dictionary of their own systems. 6.2 If the content of this standard cannot meet a certain need, you can propose the content to be supplemented and report it to the standard management unit for supplementation in the corresponding discipline, and give a code for use. You are not allowed to add words or codes on your own. In this way, you can meet the needs and maintain the stability of the standard. 7 Code table content settings
In order to meet the needs of database construction and international communication, the classification and code table has four columns: code, Chinese name, English translation (paleontology is Latin name) and remarks.
