Experimental Analysis and Application of Coal Mining Fully Mechanized Mining Process with Coal Release Step Spacing
Coal,as an important form of energy in China,can improve the production and quality of coal through the improvement of coal mining technology in the process of comprehensive coal mining.As an important process parameter in the coal mining process,the coal mining step spacing must be selected reasonably for different coal seams.Using experimental analysis,a simulation experiment was conducted on the coal release step spacing of thick coal seams.Different colored stones were used to simulate the flow effects of top coal and direct top coal.Through experiments,the top coal produced by three different coal release step spacings,namely one mining and one release,two mining and one release,and three mining and one release,was analyzed to provide application references for coal mining.
