Abstract: In view of the existing problems and process characteristics of perforated completion pipe used in gas drainage boreholes at present, the paper analyzed the coal particle size and determined the slot width of screen pipe. The different models of different slotted pipes are built; the confined compressive strength and insertion strength is analyzed by Ansys Workbench. The study shows that the flow area rate is increased from 4% to 12% by reducing the slot spacing when the slot width is 6 mm; the confined compressive strength and insertion strength of circular hole screen pipe have a little change; although the insertion strength of axis slotted pipe is larger, but its confined compressive strength is the least; the confined compressive strength of circumferential slotted pipe is 1.5 times as the circular hole screen pipe, its insertion strength is up to 1 050 N, which fully meets the needs of 700 N thrust for running 200 m slotted pipe.
