摘要
针对准能黑岱沟选煤厂入厂煤品种多、质量波动大而出现的洗选产品质量不稳定、装车配煤误差大、合格率低的实际情况,提出了实行全系统的质量管理理念并在全厂推行,以期改善装车配煤的效果。简述准能黑岱沟选煤厂的概况,结合其工艺流程分析了推行“按质配仓”理念前全厂在煤质管理方面存在的问题,从改造思路、推行内容、操作方式等方面阐述了推行理念的具体方案及其相应的煤质管控措施并分析其效果与经济效益。通过建立快捷的煤质预报体系、安装全生产线的在线灰分仪、制定严格的煤质指标考核、提升采制化系统的速度与精度、总结煤质管理中的问题等方面实行全面煤质管控,有效地提高了产品煤质量的稳定性。
Regarding to the actual circumstances of Heidaigou coal preparation plant such as unstable quality of washing products,large error of the loading and coal blending and low pass rate caused by too many types of incoming coal and large fluctuations of coal quality,the complete quality management methods were put forward and implemented in the coal preparation plant,therefore,the effect of loading and coal blending could be improved.This paper introduced general circumstance of Heidaigou coal preparation plant,combining with the process flow,the existing problems before implementing warehousing by quality were analyzed.From aspects such as transformation ideas,promotion content and operation method,the specific plan of idea promotion and corresponding coal quality management and control measurements were demonstrated,as well as the effect and profit.The stability of coal quality has been effectively improved by method as below:establishing a fast coal quality forecast system,installing online ash meter in the whole production line,formulating strict coal quality index assessment,improving the speed and precision of the sampling and sample preparation and testing system,summarizing the problems in coal quality management.
