The invention discloses a full-automatic gas ultralimit preventing device, which comprises a high-pressure capsule hole fixing apparatus, an automatic reset hole sealing apparatus and a buffer box which are sequentially connected. The high-pressure capsule hole fixing apparatus utilizes capsules to replace cement to serve as a hole fixing medium, so that hole fixing time is greatly reduced, and reuse is further achieved; the automatic reset hole sealing apparatus achieves a normally-closed function through force provided by a nitrogen spring, can clamp a drill rod under the situation without an external power source and achieves the purpose of plugging burst gas. In general, the gas ultralimit preventing device improves work efficiency, achieves an automatic plugging function in gas emission moment, also can achieve the plugging function when losing the power source and effectively ensures construction safety.
