The invention discloses a safe effective driving method and device for a high gas or outburst coal seam shield, and belongs to the field of safety and mining. The device comprises an outburst prevention shield shell body, a digging and cutting system, a gas drainage coal discharge device, a support protection system, a gas drainage system, and a foam dust control and explosion prevention system. The outburst prevention shield shell body plays a role in supporting various systems, is in close contact with a surrounding rock of a roadway to prevent deformation and outburst of the surrounding rock, a cutterhead of the digging and cutting system digs and cuts a coal seam or a rock layer in front of a working face, the coal and the rock is outputted by the gas drainage coal discharge device toa reversed loader or a belt, the support protection system plays a role in laying a net, supporting, drilling, and anchoring the surrounding rock, a propelling system is in charge of moving the shellbody and other various systems forwards and rotating the shell body and the cutterhead, and the gas in the double-layer shell body and the spiral coal discharge device is drained. The device has the advantages that the driving speed is high, the coal and the gas are prevented from bursting out and the gas is prevented from spraying to the roadway space, the safe driving is guaranteed, and the like. The safe effective driving device is particularly suitable for directly driving the roadway for the high gas or outburst coal seam.
