作为煤炭质量检测的第一环节，煤炭采样技术在实际生产运用中有着十分重要的作用。基于我国煤炭产业升级和采样技术深度发展，从不同领域用煤企业实际需求出发，介绍了目前我国煤炭采样方式主要有人工采样和机械采样方式，机械采样根据应用场合又分为汽车煤采样、火车煤采样、溜管输煤采样和输送带输煤采样；综述了目前我国煤炭采样技术采用的采样标准，综述了输送带输煤采样技术在国内外的应用现状及发展历程；归纳了输送带输煤采样装置按采样位置不同分为输送带端部采样装置和输送带中部采样装置，分析了输送带端部采样装置和输送带中部采样装置的几种常见类型，并系统介绍了采样装置不同类型的结构、工作原理以及存在的主要问题；通过对目前输送带输煤采样技术及装备的现状分析，总结了目前我国输送带输煤采样技术存在的4个主要问题：①〖BP(〗=1\*GB3〖BP)〗大多数采样作业未严格按照采样标准进行；②〖BP(〗=2\*GB3〖BP)〗采样技术的基础研究还不够深入，采样设备的关键结构还存在一定缺陷；③〖BP(〗=3\*GB3〖BP)〗采样设备智能化、自动化程度低；④〖BP(〗=4\*GB3〖BP)〗采样设备管理人员专业素质不高。因考虑将智能化控制及检测技术与采样技术深度融合，不断完善采样标准、提高采样设备自动化、智能化程度以及提高输送带输煤采样机械适应能力，是未来我国输送带输送采样技术的发展方向。

As the first link of coal quality testing, coal sampling technology plays an important role in the actual production and application. Based on the upgrading of China’s coal industry and the in-depth development of sampling technology, starting from the actual needs of coal-using enterprises in different fields, it is introduced that the current coal sampling methods in China mainly include manual sampling and mechanical sampling. According to the application situation, mechanical sampling is divided into automobile coal sampling, train coal sampling, chute coal sampling and conveyor belt coal sampling. The sampling standards of coal sampling technology in China are summarized, and the application status and development of coal sampling technology with conveyor belt at home and abroad are summarized. The coal sampling devices of conveyor belt are divided into conveyor belt end sampling devices and conveyor belt middle sampling devices according to different sampling positions. Several common types of conveyor belt end sampling devices and conveyor belt middle sampling devices are analyzed, and and the different types of sampling devices are systematically introduced. Through the analysis of the current situation of coal sampling technology and equipment of conveyor belt, four main problems existing in coal sampling technology of conveyor belt in China are summarized : ① Most of the sampling operations are not carried out in strict accordance with the sampling standards ; ② the basic research of sampling technology is not deep enough, and the key structure of sampling equipment still has certain defects ; ③ the sampling equipment is intelligent and the degree of automation is low; ④ the professional quality of the sampling equipment management personnel is not high. Considering the deep integration of intelligent control and detection technology and sampling technology, continuously improving sampling standards, improving the automation and intelligence of sampling equipment, and improving the adaptability of conveyor belt coal conveying sampling machinery are the future development direction of conveyor belt conveying sampling technology in China.
