When the coal miners move the escape room 2, the coal miners operate the control panel installed on the front side of the sealing door 4, so that the electric hydraulic telescopic cylinder 6 operates to drive the sealing door 4 to rotate and open toward the inside of the escape room 2, so that the coal miners can enter the escape room easily. 2. When the coal miners enter the escape room 2, they can observe through the observation window whether the position where the rear side of the escape room 2 is connected to the escape passage has collapsed. If no collapse occurs, they can escape and evacuate from the escape passage at the rear side of the escape room 2. In this case, if the escape passage also collapses, the personnel can wait for rescue in the escape room 2. The device has a simple structure and is easy to operate. The sealing door 4 is provided to facilitate sealing the front and rear sides of the escape room 2, so that the external debris will not enter the escape room 2 when the coal mine shaft collapses.
