In the process of measuring the binding index of bituminous coal,the influence of stirring process on the results varies with different coal types.In the detection,except for the mixing process,other experimental conditions remain the same,the mixing direction and Angle stipulated in the national standard GB/T5477-2014 were further verified according to different coal types.At the same time,the human stirring and automatic stirring instrument are compared.The results show that the mixing direction can be adjusted according to the habit,which has little effect on the results.The increase or decrease of stirring Angle has influence on the result,and the difference is great among different kinds of coal.At the same time,the verification results can be used to standardize the experimental operation,and find the cause of error when the results appear.The comparison result between personnel and equipment is similar,and the stability of equipment is better.
