Description

Technical Field

[0001] The utility model relates to the technical field of coal mine tunnel sealing, in particular to an emergency backpack box for coal mine tunnel sealing. Background Art

[0002] In the process of blocking the coal mine tunnels, brick and stone stacking or concrete are usually used to block the tunnels. However, when blocking the tunnels in this way, brick and stone or concrete and other materials need to be transported to the vicinity of the coal mine tunnels. When the coal mine tunnels are blocked, the coal mine tunnel space is relatively small and the transport vehicles are relatively large in size, so it is difficult to enter the vicinity of the tunnels that need to be blocked. The transport vehicles are likely to stay at a position far away from the tunnels that need to be blocked, and then they are transported to the vicinity of the coal mine tunnels that need to be blocked by personnel. Since a large amount of brick and stone or concrete is required in the process of blocking the tunnels, the labor intensity of the personnel is increased and it takes a long time, and the blocking efficiency of the coal mine tunnels is poor.
