Chinanews.com, Yantai, January 15th, title: Wushan, Qixia, Shandong mine disaster: the difficulty of rescue and safety of miners affect people's hearts
China News Service reporter Yang Bing and Wang Jiaoni
As of 14:00 on January 15, 120 hours have passed since the Qixia mine disaster in Shandong Province. For the lives of 22 trapped miners, rescue is still underway against the clock.
Five days ago, there was an explosion in this gold mine, and the underground workers have lost contact.
The reporter came to the site of the incident again on the 15th. The dirt road after the snow melted was very muddy. In the past few days, rescuers, various mechanical equipment, as well as emergency, fire, public security and other vehicles have rushed for rescue through this four to five meters wide dirt road. First line.
At present, a total of 6 drill holes are being rescued at the same time.

Approaching the rescue site, a number of drilling rigs stood high, with drill bits continuously drilling underground.
Drilling down from the ground is to open up another life channel for the trapped persons for ventilation and delivery and feeding.
As the depth increases, the difficulty of drilling increases.

The explosion occurred in the "One Middle Section" (240 meters from the wellhead) of the Hushan 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).
At present, a total of 6 drill holes are being rescued at the same time.
As of 12:00 on the 15th, one of the drill holes had been completed with a footage of 526 meters, and there were more than 100 meters left from the location of the trapped persons.

However, as the depth increases, the difficulty of drilling construction increases. Due to the complex geological conditions, the cracks in the rock formations can easily cause the drilling to "stuck", resulting in slow or even stagnation of individual drilling rigs.
At the same time, after the borehole and the roadway are connected, if the water inflow is large, it is easy to cause the water level in the well to rise, posing a threat to the safety of the trapped personnel.
The rescue headquarters is adjusting the construction plan in time through real-time detection of water inflow from the borehole.
Following the route where the rescuers ran, they came to the center of the rescue—the head of the air return shaft.
In the past few days, rescuers have tried to open a passage from here, but there are many difficulties.
The explosion caused the destruction of the facilities in the shaft. A large number of obstacles were piled up. The air supply, water supply and drainage pipelines, power supply and communication cables, and facilities between the ladders fell off and stirred up each other. There were also mining carts blocked in the shaft. The thickness of the blockage was initially detected Up to 7 meters, it is very difficult to clear obstacles.
Up to now, the removal of obstacles in the return air shaft still stays more than 340 meters above the ground.

Up to now, the removal of obstacles in the return air shaft still stays more than 340 meters above the ground.
The reporter learned at the scene that in order to ensure personal safety during obstacle clearance, in accordance with the principle that people and objects cannot be mixed and lifted, operators need to evacuate when lifting obstacles, which also leads to a long obstacle lifting cycle.
At the same time, in order to prevent the generation of harmful gases, hydraulic cutting machines can only be used to cut cables and wire ropes, and gas cutting can be used to cut metal obstacles, which is inefficient.
At present, there are 11 professional rescue teams and 1 fire rescue team, with 431 rescuers and 265 sets of various machinery and equipment.

"At all costs and by all means, under the existing technical conditions, we will continue to use multiple methods to solve rescue difficulties in a targeted manner and try our best to rescue the trapped people." The rescue headquarters is constantly adjusting its plans to ensure that the rescue is accelerated. Advance.
Five days have passed since the accident. The responsible person of the accident responsible unit has been under control due to the late reporting of the mining accident. What is waiting for him will be serious investigation and accountability. The cause of the accident has also been investigated simultaneously, and the safety of the miners is still unknown. Affect people's hearts.
On the same day, Qixia, Shandong, snow fell again, and a new round of cooling is coming, but the rescue is non-stop, and the rescue team and equipment continue to increase. At present, there are 11 professional rescue teams and 1 fire rescue team, with 431 rescuers. 265 sets of similar machinery and equipment were put into rescue.
The helmets of different colors on the rescuers' heads represent different responsibilities, but there is only one goal-for the lives of 22 miners.
