Abstract: This paper briefly introduced the present situation of exhausting and mining of coal seam extraction holes in Liyazhuang
Coal Mine, and analyzed the influence factors of the gas extraction effect by using borehole mining, pointed out that the most
important thing in the design process of drilling gas extraction parameters is to reasonablely determine hole sealing materials and
extraction pipe diameter, and proposed hole sealing materials and optimization method of extraction pipe diameter in coal seam
extraction holes. Field application effect showed that the method has extensive application value for guiding drilling drainage
parameters design.

Key words: gas extraction; pipe diameter; extraction effect
