Abstract: LIMS is an information management system specially designed for laboratories. The introduction of the system by mining enterprises can help realize the digital management of testing business. However,the general-purpose LIMS software on the market generally has defects such as incomplete integration with CNAS system,imrigorous process management and weak industry applicability,which cannot meet the special needs of mining industry laboratories. Therefore,combined with the requirements of CNAS quality management system and the characteristics of mine laboratory testing business,a LIMS system that meets the characteristics of metal mining industry has been developed,and the traditional laboratory testing business management mode has been comprehensively reformed and improved. The content covers business management,testing process,result summary,report management,report traceability and CNAS system operational guidance. The system introduced the concepts of sample type,equipment type,laboratory post,reproducibility limit setting and report authority setting,and established the correlation relationship. It can batch commission test tasks and flexibly set the user report approval authority. According to the correlation relationship,the system can automatically assign the detection task to a specific detection team and laboratory post,automatically calculate the reproducibility limit of the detection item,determine whether the parallel detection result is out of tolerance,and clarify the retest method and the calculation method of the average result. In addition,the system uses the LTIoT data acquisition platform to achieve automatic data acquisition of analytical instruments,balances,hyhumidity meters,twodimensional codes,etc. ,to ensure data accuracy,completeness and traceability. It effectively avoids the errors and uncertainties caused by the traditional manual entry. The application results show that the development and application of the system provides an efficient,rigorous and standardized laboratory information management system for the metal mining industry,helps to improve the digital management level of the detection business,and provides strong support for the digital transformation of the industry. The application effect shows that the development and application of the system can provide an efficient, rigorous and standardized laboratory information management system for the metal mining industry. It is helpful to improve the digital management level of testing business and provide strong support for the digital transformation of the industry.
