选煤厂重介质分选运行数据集

本数据集主要面向选煤工艺优化与智能化控制研究需求建设，基于陕西榆林青龙寺选煤厂分布式控制系统（DCS）及精煤灰分在线检测系统产生。数据集系统记录了重介质分选全流程的关键运行参数，包括原煤皮带瞬时量、合格介质密度值、精煤皮带瞬时量等自动采集变量，以及精煤产品灰分这一核心质量指标（人工间隔采样结合灰分仪检测），数据采样间隔60秒（自动值）与10分钟（灰分值），数据量2.04MB。该数据集完整反映了重介分选系统在特定生产周期内的运行状态与产品质量，为研究分选过程动态建模、产品质量软测量及工艺参数优化提供了真实、可靠的工业数据基础。This dataset was developed to meet the research requirements of coal preparation process optimization and intelligent control, and is generated based on the distributed control system (DCS) and clean coal ash content online detection system of Qinglongsi Coal Preparation Plant in Yulin, Shaanxi Province. It systematically records the key operating parameters of the entire dense-medium separation process, including automatically collected variables such as the instantaneous flow rate of the raw coal belt, the density of the qualified medium, and the instantaneous flow rate of the clean coal belt, as well as the core quality indicator of clean coal product ash content, which is detected via manual interval sampling combined with ash meter testing. The data sampling intervals are 60 seconds for automatic-collected variables and 10 minutes for ash content values, with a total data size of 2.04 MB. This dataset fully reflects the operating status and product quality of the dense-medium separation system during a specific production cycle, providing an authentic and reliable industrial data foundation for research on dynamic modeling of the separation process, soft sensing of product quality, and process parameter optimization.
