Selection and Analysis of Process Parameters for Deep Coal Seam Fully Mechanized Mining Height
In the process of fully mechanized mining with high mining height in deep coal seams,high mining height is beneficial for efficient mining of coal seams,while excessive mining height has an impact on the stability of surrounding rocks.To determine a reasonable high mining height value,simulation was used to analyze the deformation of coal walls and advance tunnels at four different mining heights,in order to select a reasonable mining height and ensure efficient and safe mining of the coal mine.
