| description | The invention discloses a blast hole plugging device, a blast hole plugging method and a detection method of a presplitting blasting roof-cutting effect, belongs to the technical field of coal mine drilling blasting and coal pillar-free mining, and solves the problem that the presplitting blasting roof-cutting effect cannot be detected when stemming is adopted for plugging a blasthole in the priorart. The blast hole plugging device comprises a blast hole inner damping device and a blast hole outer damping device. The blast hole inner damping device is detachably installed in a blast hole andcomprises a water sandbag, a damper and an energy gathering pipe. The blast hole outer damping device is detachably installed outside the blast hole and used for preventing the blast hole inner damping device and explosion energy from rushing out of the blast hole. The blast hole plugging device is simple in structure, convenient to operate and capable of detecting the presplitting blasting roof-cutting effect.
