What is Study on Time Effect of Acidified Pulverized Coal Micro Components and Discussion on Mathematical Correlation of Influencing Factors about?
In this paper, 3 % HCl + 3 % CH3COOH + 3 % HF + 2 % KCl complex acid is used to dissolve pulverized coal, and the industrial analysis method, XRD and SEM experiments were used for testing. The results show that the relative contents of M, Fc, and V in coal samples increase with the dissolution time, the A decreases, the content of elements C and O increases, and the content of elements H, N, and S decreases. The effect of composite acid on the surface morphology of coal is significant. It can effectively remove the particles on the coal surface. According to the theory of factor analysis, the industrial component and element is reasonably analyzed, and the weight coefficient of industrial parts is greater than the element factor. This study provides theoretical support for the time effect of coal mine gas drainage and coal seam water injection.
