[0001] The utility model belongs to the field of metal ore mining, and specifically refers to a protective and emergency device for metal ore mining. Background Art

[0002] Metal ore mining refers to the process of processing minerals. Traditional metal ore mining technologies mainly include open-pit mining, underground mining, and ore washing. Among them, open-pit mining means directly excavating the mine to extract metal ore; underground mining is to enter the mine through shafts or tunnels to mine metal ore from underground; ore washing is to separate the metal-containing ore and extract the metal from it. During the process of metal ore tunnel mining, there are many potential safety hazards, such as falling rocks, dust collapses, and even emergencies such as earthquakes. In order to ensure the safety of mining workers, an emergency protection and emergency device needs to be set up.

[0003] The existing protective and emergency devices for metal ore mining mostly play a simple supporting and protecting role, and cannot play a good protective role when a large number of falling rocks roll in the mine tunnel.

[0021] As Figure 1 、 Figure 2 and Figure 3 As shown in

[0022] As Figure 2 and Figure 3 shown, a metal mine mining protection and emergency device proposed by the present utility model includes a protection passage 1, a blocking door 3, a spraying mechanism 4 and an auxiliary mechanism 5. The protection passage 1 is set as a square passage structure, the upper part of the protection passage 1 is set as an arched structure, control mechanisms 2 are arranged on both the front and rear sides of the protection passage 1. The control mechanism 2 includes a rotating rod 202. The rotating rod 202 is rotationally connected to the protection passage 1 and penetrates through the protection passage 1. Connecting blocks 203 are fixedly arranged at both ends of the rotating rod 202. The blocking door 3 is hinged to the connecting block 203. The spraying mechanism 4 and the auxiliary mechanism 5 are both arranged on the upper part inside the protection passage 1.

[0023] As Figure 1 and Figure 3As shown, the spraying mechanism 4 includes a water storage tank 401 and a connecting pipe 403. The water storage tank 401 is fixedly connected to the upper part inside the protection passage 1. Water pumps 402 are connected to both the front and rear sides of the water storage tank 401. Spraying pipes 404 are provided on both the front and rear sides of the protection passage 1. Spraying openings 405 are formed in the lower part of the spraying pipes 404. One end of the connecting pipe 403 is connected to the water pump 402, and the other end of the connecting pipe 403 penetrates through the protection passage 1 and is in through connection with the spraying pipe 404, which is used for spraying to reduce dust and prevent dust in the mine from entering the ventilation opening 301. A drain pipe 406 is provided in the lower part of the water storage tank 401, and a valve 407 is provided on the drain pipe 406, which is used to fill water into the water storage tank 401 and can also be used for the people taking shelter in the protection passage 1 to drink in case of emergency.

[0024] The auxiliary mechanism 5 includes a first telescopic rod 501 and a second telescopic rod 502. The first telescopic rod 501 and the second telescopic rod 502 are both arranged at the upper part inside the protection passage 1. The first telescopic rod 501 and the second telescopic rod 502 are arranged in opposite directions. There are two groups of the first telescopic rod 501 and the second telescopic rod 502 respectively, which are arranged on both sides of the upper part of the protection passage 1.
