How were the signs of life found more than 500 meters underground in the Hushan gold mine accident in Shandong Province?

The incident started at 2 pm on 20211010. A gold mine explosion occurred in Qixia City, Yantai City, Shandong Province, causing 22 construction workers to be trapped under the gold mine.

Because of the explosion accident, all the escape routes of the workers were blown up and the communication system was lost. The fire caused by the explosion not only consumes a small amount of oxygen in the mine, but also produces deadly toxic gases. At that time, workers' lives were very pessimistic. If you want to rescue workers, you must first determine the location of the workers. It is understood that this gold mine is still in the capital construction period, so it can be judged from the explosion mouth and the current work progress of the workers. The difficulty to be overcome after determining the position of workers is the transportation of underground ventilation equipment and the removal of obstacles in Wainai. Therefore, the relevant rescue leaders of the accident rescue team put forward preliminary solutions: First, it is necessary to put ventilation pipes in the wells to swat off toxic gases; The second is to make a simple bucket and cooperate with tools to clean up the waste residue produced after the explosion; Third, if life is detected, first establish a supply channel and a communication channel!

After the plan is clear, some professional equipment of various professional rescue teams are also preparing for rescue non-stop. It is understood that Du Bingjian, who has led the national rescue team to rescue more than 300 miners, is the chief commander of this rescue. I learned from Du Bingjian that this rescue is very difficult, because the geographical structure under the mine is very special, and there are many volcanic rocks, and the highest hardness grade of volcanic rocks is 12! Moreover, in this geological construction position, all drilling holes will be inclined. The key is to correct the deviation, but it takes time to correct it. If you don't have time, the restrictions are fine, and there are miners waiting to be rescued in the key underground!

Finally, good news came from 17! The drill bit finally reached the position marked by Du Bingjian, that is, it crossed the driveway! So Du Bingjian directed the rescuers to hit the drill pipe with a sledgehammer, trying to get in touch with the underground miners, but ten minutes passed and no response was received. So the rescuers continued to knock, and after another five minutes, they finally met with a response! After receiving the response, everyone dared not delay and quickly threw the materials out with wire ropes. After the wire rope was pulled up, they brought back a piece of paper, which detailed the specific situation below the mine, as well as medicines and other needed items. Every word is heavy, and every word makes rescuers happy and worried. Later, rescuers set up a wired telephone to go underground, which can guarantee to get in touch with the miners and give them the belief to live!

The rescue work is still in full swing. I hope everything goes well!
