Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mine protection, specifically is a safety device for mining. BACKGROUND

[0002] The safety device for mining refers to various technical measures and equipment taken to protect the life safety and health of workers during mining, and the safety of mining operations can be effectively improved and the risk of accidents can be reduced by comprehensively using these safety devices.

[0003] The Chinese patent with publication number CN216841740U discloses a gold mine mining safety protection device, which is provided with a combined top protection assembly installed in the top frame. The top protection assembly is composed of two mounting frames, a connecting shaft, two protection nets, and four connecting rods. The two mounting frames are symmetrically connected to the outer side of the connecting shaft. Under the cooperation of the four connecting rods and the two connecting grooves on the inner side wall of the top frame, the two mounting frames can form a V-shaped storage space when they move closer to each other. The rubble blocked by the protection net will fall into the storage space. The operator can take out the rubble through the gap between the two mounting frames and the top frame. The operator can conveniently adjust the position of the mounting frame, so that the operator can quickly and flexibly take out the rubble. The operator can conveniently clean the rubble on the protection net regularly. The device is convenient to operate and has high work efficiency, which can ensure normal use of the device for a long time. The protection net is fixed in the mounting frame by screws, which facilitates the operator to replace the protection net. The rubble falling from the top wall of the mine will be blocked by the protection net. However, it is difficult to buffer the protection net when it receives the rubble. The impact force will directly act on the net body, causing instantaneous high stress concentration and increasing the risk of damage to the protection net. The impact force of the falling object cannot be effectively absorbed and dispersed. Moreover, the protection net has no buffering function. The protection net directly faces the impact, which can easily cause tearing or breaking of the net, and thus the falling object or the personnel directly contacts the ground, increasing the possibility of secondary injury, and even causing serious accidents.
