| description | The invention relates to the technical field of mine gas disaster control, in particular to a gas extraction drilling and spraying hole self-adaption multi-stage buffering hole spraying prevention device which comprises a hole opening blowout prevention device and a gas-slag separation device which are communicated through an arranged buffering connecting pipe. The orifice blowout preventer is provided with a sleeve used for being inserted into a coal seam. A slag discharging opening is formed in the bottom of one side face of the gas-slag separation device, and a baffle is rotationally connected to the slag discharging opening in the outer side face of the gas-slag separation device; a storage box is arranged on the other side face of the gas-slag separation device, a movable baffle which is rotationally connected is arranged at the end, away from the gas-slag separation device, of the storage box, a telescopic bag is arranged in the storage box, and the telescopic bag communicates with the gas-slag separati |
