Mining deep hole sealing device triggered by blasting

The invention provides a blasting-triggered mining deep hole sealing device, which belongs to the technical field of coal mining and comprises a hole sealing column body, an anti-slip assembly, an expansion assembly, an ejection assembly and a triggering assembly. A shock wave receiving disc of the triggering assembly moves upwards after being subjected to blasting impact, the upper end of a driving connecting rod mechanism is separated from the lower ends of two longitudinal connecting rods, a compression spring of the ejection assembly releases elastic force to jack a pushing cover upwards, and the pushing cover moves upwards; firstly, a plurality of anti-slip blocks in an anti-slip assembly are pushed to move outwards along an opening structure of a hole sealing column, the multiple anti-slip blocks abut against the inner wall of a drill hole at the same time, a pushing cover continues to move upwards to extrude an elastic liquid storage chamber, and liquid in the elastic liquid storage chamber is conveyed
