Selection of Multiple Coal Drawing Methods in Thick Coal Seam Working Face
Most of China's coal is buried deep underground in the form of thick coal seams,and fully mechanized top coal caving is the main mining process.In the process of fully mechanized mining,different coal drawing methods have a significant impact on the extraction of coal seams.Simulate and analyze the impact of different coal mining methods,can provide some reference for the selection of coal mining methods in thick coal seams.The results indicate that single wheel interval coal caving has a good mining effect,and is a more suitable coal caving method for thick coal seam mining.
