Analysis of the Destructive Effect of Mining Height on Top Coal in Thick Coal Seam Caving Mining
In the top coal caving mining of thick coal seams,the mining height,as an important process parameter,has a significant impact on the destructive nature of the top coal,thereby affecting the extraction rate and quality of the coal seam.Numerical analysis was used to simulate the destructive effect of different mining heights on top coal,in order to obtain reasonable mining height parameters,improve the destructive effect of top coal,and improve the mining efficiency and quality of coal mines.
