| Abstract: | According to the coal bed gas radial flow theory model and actual situation,some factors influencing gas extraction of borehole are analyzed,and whose importance ranking can be made by using improved analytic hierarchy process(AHP). In addition,on the basis of the data of gas extraction by surface borehole No. 1 and No. 4 drilling the coal seam of its pressure released by mining for the factors of gas drainage in the surface borehole. |
