China News Service, Urumqi, April 11th. The reporter learned from relevant departments in Xinjiang on the 11th that since the afternoon of the 10th, the Fengyuan Coal Mine in Queergou Town, Hutubi County, Hutubi County, has been undergoing technological transformation since the afternoon of the 10th. After the sudden flooding accident, a total of 8 professional teams went to the scene for rescue and rescue.
At present, three pumps have been established underground to pump down water pipelines.
At 18:10 on April 10th, during the technological transformation of Fengyuan Coal Mine, Queergou Town, Hutubi County, Changji Prefecture, a sudden flooding accident caused underground power outages and communication interruptions.
According to preliminary information, 29 people were on duty when the accident occurred, and 8 people have been safely upgraded.
At present, 8 workers who have been safely promoted to the well are in good physical condition.
It is reported that the current positions of the 21 trapped persons have been basically determined. 21 people are distributed in 3 locations, of which 12 are on one of the working platforms, the other 8 are on the same working platform, and another one enters the escape route. , But there is water in the avoidance channel, so there is no more detailed information for the time being.
The working platform with 12 people is 1200 meters from the ground, and the underground terrain is complex, making rescue difficult.
After receiving the report from the Changji State Emergency Management Bureau, the 106 coal mine rescue team, 30 kilometers away from the rescue site, first arrived at the rescue site. According to the unified command of the on-site headquarters, they quickly assembled pumps and laid pipelines. The distance from the trapped personnel was 1,200. Mi's auxiliary well head quickly launched rescue.
"The water level is about 140 meters away from the auxiliary wellhead. We send the water pump from the auxiliary wellhead to pump water. As the water level drops, we move the pump forward." said Bao Yongsheng, deputy governor of Changji Prefecture. At present, three units have been installed in the well. The pump can discharge 440 cubic meters of water per hour.
One is being perfected and the auxiliary well head can drain 840 cubic meters of water per hour after it is put into use.
Bao Yongsheng said that from the auxiliary wellhead to the location of the trapped personnel, there is a lowest point about 400 meters away from the trapped personnel.
The trapped ground has a height difference of 19 meters from the lowest point.
The roadway is 3.3 meters long, and the roof is capped after the water passes.
After capping, the air is closed, forming an air column.
When the air column pressure reaches a certain level, the water level will no longer rise. "We believe that the trapped people have the possibility of survival."
As of press time, 1,484 rescuers and 854 professional personnel were directly involved on the scene.
Among them, there are 33 from Xinjiang Mine Rescue Corps, 21 from Changji Emergency Mine Rescue Team, 36 from National Energy Rescue Team, 17 from National Emergency Rescue Xinjiang Bayi Steel Team, 21 from 106 Coal Mine Rescue Team, and 6 coal mines in Hutubi County. There are 54 emergency rescue teams, 260 armed police forces, 50 fire rescue teams, and 400 public security officers.
In addition, 25 ambulances were mobilized, and more than 60 ambulance personnel rushed to the scene to carry out medical rescue and on-site medical security work.
The Xinjiang Health Commission led 43 medical personnel of the National Emergency Medical Rescue Team to the scene, which can carry out medical treatment for 30 personnel at the same time.
"Next, we will set up a 400 cubic meter/hour water pump with all our strength to put it into use as soon as possible." Bao Yongsheng said. At the same time, the rescue team will open the return air inclined well south of the auxiliary wellhead and put in the fourth pump. .
"The water on the return air inclined shaft has been closed, and the harmful gas in it has exceeded the limit. We will install a local fan, after the harmful gas is discharged, the pipeline will be quickly laid, and the water pump will pump water." (End)
