Emergency reinforcing and supporting device for mining

Abstract

The invention discloses an emergency reinforcing and supporting device for mining, and belongs to the technical field of mining. The emergency reinforcing and supporting device comprises a supportingair supply mechanism. A first damping assembly is fixed to the top of the supporting air supply mechanism. A reinforcing mechanism is fixed to the top of the first damping assembly. A height adjustingmechanism is fixed to the top of the reinforcing mechanism. A second damping assembly is fixed to the top of the height adjusting mechanism. A lifting protection mechanism is fixed to the top of thesecond damping assembly. According to the emergency reinforcing and supporting device for mining, the interior of the height adjusting mechanism is rapidly inflated through compressed air in an air tank in the supporting air supply mechanism, so that the air pressure in the height adjusting mechanism is increased, a fixing plate can be rapidly pushed to move upwards and is limited and fixed underthe action of a set of clamping plates, therefore, the lifting protection mechanism above the height adjusting mechanism is matched to quickly reinforce and support the top of a tunnel, the use efficiency of the device is greatly improved, the use steps of the device are reduced, and the survival probability of workers is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of mining, and in particular relates to an emergency reinforcement support device for mining. Background technique [0002] Mine refers to an independent production and operation unit that extracts ore with a certain mining scope. Mine mainly includes one or more mining workshops (or pitheads, mine shafts, open pits, etc.) and some auxiliary workshops, and most mines also include beneficiation plants. Mines include coal mines, metal mines, non-metal mines, building materials mines and chemical mines, etc. Mine scale (also known as production capacity) is usually expressed by annual output or daily output. Annual output refers to the amount of ore produced by a mine every year. According to the size of output, it is divided into three types: large, medium and small. The size of the mine should be compatible with the economically reasonable service life of the mine. Only in this way can we save infrastruct...

Problems solved by technology

[0004] However, because there are many uncertain factors in the mining process, the tunnels will still partially collapse during the mining process. In order to increase the chances of workers' survival, it is necessary to quickly carry out necessary reinforcements on the tunnels to ensure The safety of the tunnel increases the survival probability of the trapped workers and wins more rescue time for the rescuers

However, the existing emergency reinforcement support device for mine development is relatively cumbersome in the use process, and because the device has a large self-weight, it is very time-consuming and labor-intensive in the process of assembly and use, which is not conducive to the rapid use of it by workers. It cannot meet the actual use requirements of rapid tunnel reinforcement; at the same time, the existing emergency reinforcement support devices used in mine development have poor shock absorption. The stability of the tunnel is low, which is not conducive to the protection of workers and reduces the probability of workers' survival; finally, the emergency reinforcement support device used in the existing mine development cannot be fixed and adjusted according to the terrain of the tunnel during the fixing process, which leads to its use The stability during the process is reduced, and the compressive performance is weakened, which will also directly affect the stability and safety of the reinforced tunnel.
