Self rescue and mutual rescue of the hottest mine

Self rescue and mutual rescue of mine transportation accidents

bucket is a kind of accident that occurs more in mine hoisting and transportation. Its injury to passengers is a strong impact on the bottom of the cage, which can cause leg fractures and other injuries. The self-help and mutual rescue measures of passengers during tank cleaning are:

(1) people who often ride the cage know that when the cage drops to more than 30 meters from the parking position, they will slow down. If you don't slow down when you arrive here, passengers should be prepared mentally and take measures to prevent damage to themselves caused by canning

(2) when there are not many people in the cage, they should be scattered to both sides. The people taking the tank should hold the handrail in the tank with both hands, and lift the air to make their hands hard. If conditions permit, they can make their legs suspended in the air, so as to reduce or avoid the injury to human body, especially the legs, when pouring the tank

(3) when there are many people in the cage, it is impossible for everyone to hold the handrail in the cage. The person who does not hold the handrail should also stand on both sides, grasp the person holding the handrail, and bend his legs. In this way, the impact on the bottom of the tank due to the inertial operation of the human body can be reduced, so as to reduce the injury to the tank passengers

(4) after the can accident, the uninjured personnel should stand on the surface of the steel and use electroplating, hot plating and other methods to coat a layer of metal that is not easy to rust, that is, carry out emergency treatment such as hemostasis, bandaging and temporary fixation of fractures for the injured miners on site, and quickly transport them to the hospital for treatment

2. Self rescue and mutual rescue measures for passengers when the cage is broken

(1) when the passengers find that the cage operation is abnormal, if the upward operation suddenly changes to the downward operation with high strength and extra thickness as the main direction and slows down and stops, and the downward operation suddenly speeds up and slows down and stops, they can basically conclude that the cage has broken the rope accident

data line shielding treatment (2) in the process of the above changes in the cage operation, the can passengers should hold the handrail in the cage, and those who cannot hold the handrail should hold the person holding the handrail, so as to avoid falling and other injuries when the cage stops quickly

(3) after the cage slows down and stops stably due to the action of the safety device, the person riding the cage must be calm, and must not run back and forth, push and pull in the cage. Calling should be the main way to send a distress signal, so as to maintain the balance of the cage

(4) no matter whether the cage stop is close to the ladder room of the shaft or not, people in distress should not open the tank cap and risk entering the ladder room. Such disadvantages include: first, it destroys the balance of the cage, resulting in the occurrence of tank falling accidents; Second, there is a great danger in the process of entering the ladder room. If you are not careful, you will fall into the bottom of the shaft. Therefore, the tank passengers must wait patiently for rescue

(5) the method of rescuing the people in distress in the cage after the rope is broken is: if the cage is stopped on the side close to the ladder, after taking fixed insurance measures for the cage, put up a board to let the people in distress directly enter the ladder to escape; If the cage stops on the other side, the other cage can reach the stop, and then take safety measures to evacuate the people in distress to the rescue cage, and then lift out of the well

3. Bucket overturning self rescue measures after passengers are thrown out

some small buckets will overturn during operation and dump people out of the bucket due to the poor grasp of passengers' center of gravity. However, because the personnel tied the safety belt and hung the safety hook when riding the bucket, the personnel were hoisted around the steel wire rope after getting out of the bucket and would not fall to the bottom of the shaft. Generally, there would be no serious injury often used in large railways, highway bridges, roof trusses, crane beams, industrial and civil precast floors, pipe piles, prestressed concrete transmission pipelines, etc. The self rescue measures are:

(1) when the bucket is overturned and the passengers are dumped out of the bucket, the people in distress should not grasp the guide ropes on both sides of the bucket. Because the guide rope is fixed, and the winch driver does not know that the bucket and the poured out personnel are still running with the wire rope after the bucket is overturned. If you grasp the guiding rope, you will not only be unable to save yourself, but also have traumatic accidents

(2) after the passengers are dumped out of the bucket, the bucket will automatically return to its original position due to the effect of the center of gravity. The person in distress who is suspended around the steel wire rope should grasp the top edge of the bucket and close to the bucket if he cannot grasp it. When conditions are met, try to climb into the bucket

(3) when the passengers are suspended around the steel wire rope, don't be too nervous and afraid, and quickly recover their senses. After getting close to the bucket, call and knock the bucket to send a distress signal. When the bucket is about to fall off the hanging plate, the distress signal should be sudden and loud

(4) when the bucket is about to fall onto the hanging plate, the person in distress should pay attention to the position of his body. If his legs may enter the bucket seat and be pressed by the bucket, he should push the bucket with force (the bucket cannot be pushed), and the person can move outward under the reaction of the bucket, leave the bucket seat position, and avoid injury
