after the support frame is installed, the anti-collapse net (26) is connected with the support plate (12) through the hook (25), the outer side of the anti-collapse net (26) is connected and fixed with the mine wall through the expansion bolt (27), then fixing the connector (28) on the mine in the middle of the anti-collapse net (26), finally connecting the connecting rod (29) with the connector (28) through screw threads, lifting the middle of the anti-collapse net (26) upwards, when the mine is about to collapse, the collapsed gravels fall on the anti-collapse net (26) to make the anti-collapse net (26) sink and pull the anti-collapse block (31), when the gravity on the anti-collapse net (26) is increased, the anti-collapse net (26) breaks the safety rod (30) made of the metal material with fragile mass, so that the anti-collapse block (31) falls off, thereby make warning area (33) drop under the effect of weight piece to make warning area (33) flagging, remind the staff to inspect the mine.
