Abstract: With the coal mining technology innovation, new hierarchical structure of gas extraction method and technological
innovation were optimized in coal mining enterprises, including extraction with long borehole in bedding intensive area, grid type
borehole extraction throughout coal seam and long borehole extraction in roof. This paper made detailed analysis of the above
extraction method in order to provide a reference basis. Key words: gas extraction; technological innovation; grid-type; hierarchical structure
