Food and light sticks.
"There are gaps in the wellbore obstacles. Our operators must bring some food when they go down the well, and put some down, including peanuts, small breads, and biscuits." Sun Yingxiang said that he has not received feedback from the underground for the time being.
Rescue work insists on "two legs" in parallel, on the one hand, speeding up the clearing of obstacles in the return air shaft, and on the other hand, speeding up the opening of life-saving holes.

The reporter learned from the rescue headquarters that as of 12:00 on the 16th, the depth of the wellbore was 350 meters.
Due to the accumulation of more obstacles in the return air shaft, the cleaning process is relatively slow.
At the same time, a total of 6 drill holes were arranged at the rescue site for rescue. Among them, No. 1 drill hole (diameter 311mm) completed 570 meters, which was closer to the trapped people.
At the rescue site, there were 357 sets of various machinery and equipment, and the number of rescuers increased to 439.

At present, the on-site rescue insists on "two legs" in parallel, on the one hand, speeding up the clearing of obstacles in the return air shaft, on the other hand, speeding up the opening of the rescue hole.
At the rescue site, there were 357 sets of various machinery and equipment, and the number of rescuers increased to 439.
On that day, the lowest temperature in Qixia City was ten degrees below zero. The reporter's hands and feet were frozen due to the cold during the interview. It is hard to imagine the rescuers.
The reporter also learned from the rescue headquarters that the current rescue is facing multiple difficulties.
One is that the mineralized zone of the gold mine is located in the fault, and the broken stratum is easy to "stick" and affect the drilling progress.
Second, the joints and fissures of the rock formation are relatively developed, which makes the boreholes easy to deviate.
The third is that there is a lot of water in the drilling, and the introduction of water into the tunnel will cause danger to the trapped personnel.
Fourth, the surrounding rock near the ore body is mostly granite, with very high hardness, which causes slow progress.
"Do everything possible, race against time, and do everything possible to rescue the trapped miners." The accident has been established by the Mine Rescue Center of the Emergency Management Department, Beijing Mining and Metallurgy Group, China Coal Fifth Construction Co., Ltd., Shandong Gold Group, Shandong Energy, Shengli Oilfield, etc. An expert team composed of more than 30 people in the unit conducted on-site research and judgment to guide rescue plans, and mobilized professional rescue teams such as the Longkou Mining Group Co., Ltd. Mine Rescue Team, Zibo Mining Group Co., Ltd. Mine Rescue Team, and Yanzhou Coal Co., Ltd. Military Mine Rescue Team. The team and Yantai City Fire Detachment stationed at the scene to carry out rescue work.
The emergency rescue headquarters also mobilized the most advanced international drilling rigs from Yulin, Shaanxi, Huainan, Anhui and other places, opened green channels, and rushed to the site day and night to carry out drilling operations.
At 14:00 on January 10, an explosion occurred in the Hushan Gold Mine of Shandong Wucailong Investment Co., Ltd., Qixia City, Yantai City, Shandong Province, causing 22 underground workers to be trapped and lost contact.
The explosion occurred in the "first middle section" (240 meters from the wellhead) of the gold mine, and 22 miners were located in the "six middle section" (698 meters from the wellhead) and the "fifth middle section" (648 meters from the wellhead).
