Although modern mining equipment is very advanced, people still need to go down to the mine. Although there will be safety measures in the mine, there are still risks. Although the wages of mine workers are not low, they are also making money with their lives. The biggest fear of mining is accidents. An accident occurred in Hushan Gold Mine in Qixia, Shandong Province, and more than 20 miners were trapped underground. A dozen miners were rescued afterwards, but ten people were still killed. Some people lost contact in the accident, and rescuers are also trying their best to search and rescue. Mine accident rescue is more difficult, because there are many obstacles underground, and the underground water rises, which will increase the difficulty. Moreover, there is no ventilation in the mine, and poisoning accidents may occur.

First, it is difficult to clean up the obstacles and accumulated water under the mine. The Qixia gold mine accident successfully rescued 1 1 person, but rescuers could not go down to the mine to rescue. Because the mine is not like the ground, you can see at a glance what is going on. The scale of the mine is not large, and there are many obstacles in it. Moreover, in the event of an accident in a mine, it is difficult to discharge groundwater. In this accident, the water gushing in the sixth middle section of the mine was close to the roof of the roadway, and rescuers could not search carefully at all.

Second, there is no ventilation under the mine, which is prone to poisoning incidents. It is still very difficult to ask for help under the mine. There is no ventilation in the mine. In the event of an accident, toxic and harmful gases may also leak, leading to poisoning of trapped people. Because there are many uncertain factors in the mine, rescuers can't easily enter, so as not to cause greater losses.

Third, it is easy to explode, causing secondary injuries. Ten miners were killed in the Qixia gold mine accident. The main reason is the secondary explosion in the mine. There is no ventilation in the mine, and some combustible gas leaks easily lead to explosion. Accidents and explosions increase the possibility of accidents for people trapped in mines. Therefore, in the event of an accident in the mine, you should ask for rescue at the first time. The longer the time, the greater the risk.
