The invention discloses a gas pumping sleeve-penetrating occluder and a use method thereof. The occluder is mainly formed by jointing a bag A combination and at least one bag B combination; the bag A combination comprises a No.1 bag (14),a grouting pipe (1), a gas leaking handling pipe and a transition part; the grouting pipe and the gas leaking handling pipe respectively penetrate through the No.1 bag; a check valve is arranged on the grouting pipe in the No.1 bag; the bag B combination comprises a No.2 bag and a grouting pipe penetrating through the No.2 bag; a check valve is arranged at the grouting pipe in the No.2 bag; short grouting pipes between the bag A combination and the bag B combination are jointed by a straight joint; a pumping pipe penetrates through the No.1 bag and the No.2 bag. According to the gas pumping sleeve-penetrating occluder and the use method thereof, one bag A combination and multiple bag B combinations can be serially connected, more effective grouting hole sealing can be realized on drill holes of a hole sealing section, generation and expansion of coal wall seams around the drill holes at the hole sealing section can be more effectively avoided, and the occluder can also fill extremely small coal seams, so the hole sealing effect is optimal.
