Abstract:
Recent years,the steep inclined coal seam has been depicted in some China's mining areas,especially in western part of China,which has a wide promising prospect in the future.In this paper,the development of coal mining methods and the present status of fully mechanized coal mining about steep inclined coal seam in China is summarized,analyzed and evaluated.The result points out that,in order to achieve high production and efficiency in steep inclined coal seams,the key technical points lie in:1)mastering the principles of strata pressure behavior systematically;2)pursuing further innovation in the mining methods;and 3)improving the stability of coal mining equipment in working face.To solve the technical problems,the research should be conducted with the principles of strata pressure behavior.What's more,the coal mining methods and equipment should be further developed,which provide reliable integrated solutions for the steep inclined coal mining.
