Abstract Coal quality management is an effective way to improve product quality and enhance economic benefits of coal preparation plant. Based on the actual situation of Nalinhe Coal Preparation Plant, this paper adopts scientific management measures to strengthen coal quality management. The results showed that the ash content, moisture content and sulfur content of clean coal and blended coal decreased by 0.26 %, 0.28 %, 0.17 % and 6.14 %, 0.31 %, 0.05 %, respectively, and the calorific value of the product increased by 24 Kcal / kg and 612 Kcal / kg, respectively, indicating that the coal quality management measures adopted effectively improve the product quality and provide some reference for relevant coal preparation plants.
