Introduction

GB/T 15663.1 is an important basic standard in the coal industry. Since its promulgation and implementation, it has played a significant role in standardizing coal research, teaching, and mine shaft operations. The formulation and implementation of relevant engineering standards have played a positive role. GB/T 15663 aims to define coal mine technical terminology and is composed of 10 departments. Composition. ---Part 1.Coal Geology and Exploration. The purpose is to define the terminology related to coal geology and exploration, along with their English translations and definitions. and symbols. ---Part 2.Shaft and Tunnel Engineering. The purpose is to define the basic terminology of shaft and tunnel engineering, shaft and tunnel excavation, shaft and tunnel support, and conventional shaft sinking methods. Terms such as drilling method well sinking, freezing method well sinking, grouting method well sinking, caisson method well sinking, well equipment and facilities, etc. ---Part 3.Underground Mining. The purpose is to define terminology related to minefield development, mining methods, mining area support, and mine surface facilities. ---Part 4.Open-Pit Mining. The purpose is to define the relevant stope elements, development and mining, production process systems, and technologies for open-pit mining. Terms such as technical economics. ---Part 5.Lifting and Transport. The purpose is to define the terminology for vehicle transport, conveyor transport, wire rope transport, and lifting. ---Part 6.Mine Surveying. The purpose is to define the main terminology in the scientific and technical field of mine surveying, covering surface surveying in mining areas. The scope includes quantity surveying, mine surveying, mining subsidence and prevention, basic surveying instruments and tools, mine maps and mine spatial information. ---Part 7.Mining Subsidence and Special Mining Techniques. The purpose is to define the main technical aspects of mining subsidence science and special mining techniques. The terminology covers aspects such as coal mining subsidence, special mining methods, and prevention of mining-related damage. ---Part 8.Coal Mine Safety. The purpose is to specify regulations regarding mine atmosphere, mine ventilation, instrumentation, gas, dust, mine fires, and mine safety. Terms such as first aid and rescue. ---Part 10.Mining Machinery. The purpose is to define general terminology, including terms for coal mining machinery, tunneling machinery, and hydraulic supports. ---Part 11.Coal Mine Electrical Equipment. The purpose is to specify the power supply, electrical equipment used in coal mines, key electricity consumption indicators in coal mines, and other relevant regulations. Terms such as monitoring and control, coal mine communication, and coal mine informatization. Due to the length of the document and the different needs of its users, this document is designated as Part 1 of GB/T 15663 "Coal Mine Technical Terminology". The terminology related to coal geology and exploration should be defined. GB/T 15663.1-2008 is no longer suitable for the requirements of the development of the situation. Its main problems are. (1) the basic theory of coal geology and exploration. With the rapid development of technologies and methods, new national standards for mineral resource reserve classification and new mineral geological exploration specifications have been implemented one after another, resulting in a large number of... (2) New terms and concepts have been introduced, and existing standard terms can no longer cover the main scope of coal geology and exploration research; Since these terms have been phased out and are no longer in use, there is no need to retain them. Coal Mine Technical Terminology Part 1.Coal Geology and Exploration

1 Scope

This document defines the terminology related to coal geology and exploration, along with its English equivalents, definitions, and symbols. This document applies to standards, regulations, specifications, documents, textbooks, books, and manuals related to coal geological exploration.

This document has no normative references. 3.The origin and composition of coal 3.1 coal coal Plant remains transformed into carbon-rich, solid, combustible organic sedimentary rocks through coal formation processes. These rocks contain a certain amount of minerals and corresponding ash. Yield less than or equal to 50% (mass fraction on dry basis). Note 1.The current upper limit for coal ash content used in domestic coal resource reserve estimation is 40%. Note 2.Coal focuses on rock properties, while coal focuses on resource properties.

Note. The organic deposits that make up peat are mainly humus, primarily found in the Quaternary system, with a small amount found in the Neogene system. 3.3 sapropel Aquatic lower plant and plankton remains, through biochemical processes in deep swamps, lakes, and bays, form a rich environment...
