Preventive measures for deep well rescue
First, we should have a comprehensive understanding of the site conditions, fully grasp the nature of deep well use, and use detection instruments to detect the gas composition inside the deep well; carefully observe the surrounding soil conditions to prevent the collapse of the shaft wall in the rescue process; in the implementation of the rescue process, we should arrange a special person to be responsible for safety monitoring, and timely grasp the change information of the site conditions.
Second, we should do a good job in personal safety protection of officers and soldiers participating in the war. Due to the poor air circulation inside the deep well, there may be a large number of combustible and toxic gases in the abandoned deep well. Rescue officers and soldiers should add a lot of fresh air to the well before entering the deep well for rescue. They can take measures to replace the gas in the well, such as putting in the air respirator opening the cylinder valve or using the tunnel air supply. They must wear air breathing apparatus when going deep into the well for rescue Protective equipment such as respirator, long tube respirator, etc.
Third, rope protection measures should be taken on the ground. In the process of getting in and out of the deep well, the rescuers rely entirely on the rope traction, and even have to work in the air. Therefore, the ground personnel must take protective measures. For deep wells, the rescue tripod should be given priority, which can not only make the battle fast, but also facilitate the cooperation between the personnel on the well and the personnel in the well, so as to better control the downward and upward speed. At the same time, when the rope is used for protection, attention should be paid to wear to prevent the rope from breaking.
Fourth, we should adopt scientific rescue methods. In addition to the common use of ropes to fix the trapped persons and pull them out of the ground, if conditions permit, rescue stretchers can be used to fix and pull the trapped persons out to prevent secondary injury.
