Rescue treatment of mine water inrush accident

In the event of a water inrush accident in the mine, the personnel at the accident site shall report to the dispatching room in time according to the provisions of the Mine Disaster Prevention and Treatment Plan, and notify and organize the personnel affected by the disaster to evacuate the disaster area according to the disaster avoidance route. After receiving the accident call, the mine dispatching room should report to the mine leader and inform the rescue team and relevant departments. The disaster relief headquarters was established and organized to handle disasters in a step-by-step manner. After the establishment of the disaster relief headquarters, it is necessary to quickly determine the nature of the flood, understand the water inrush point, the scope of the impact, find out the distribution of personnel before the accident, statistically evacuate the wells, and analyze the location of the trapped personnel; according to the amount of water inrush and the drainage capacity of the mine, actively take Technical measures for discharging, blocking and intercepting water. If it is old kiln water, the amount of water is limited by the space of the old kiln, and the drainage method can be used to treat the water. If the surface water penetrates into the well, there is always sufficient water supply. First, measures should be taken to intercept the ground supply channel. Then strengthen the discharge of water in the underground. Of course, the situation of water inrush in the underground is complicated, and some or several measures can be taken at the same time according to the specific situation. At the same time, the conditions permit, the ventilation of the disaster area must be restored as soon as possible to prevent gas and other harmful gas from accumulating and causing smoke accidents. After the drainage, when conducting reconnaissance and rescue, it is necessary to prevent the occurrence of roof collapse, bottom loss and secondary water inrush accidents.

After a water-permeability accident, people are often trapped underground. Commanders should still follow the principle of "saving people is the first task", fight for time and take effective measures to get them out of danger as soon as possible. After the permeable incident occurs, the location where the person in distress may be evaded should be correctly judged, scientifically analyzed whether the location has the conditions for the survival of the person, and then the organization is actively organized for rescue. When the evasion location is higher than the external water level, the people in distress may survive. For those in these locations, fresh air, beverages and food should be delivered to them by all possible means (drilling or digging a section of the roadway) to extend the waiting time. When the refuge site is lower than the external water level, there are two cases:

(1) When the water bursts, the flood can directly flow into the roadway (such as the flat road and the mountain) located at the lower part of the water inrush point, and drown them. Under normal circumstances, there will be no air in these places, and there will be no human survival. condition. However, there have been many cases in which people have been hiding in these lanes and being rescued.

(2) When the whole section of the lower roadway of the water inrush point is flooded, the upper single roadway such as the one-headed uphill that communicates with the roadway will not be completely submerged even if it is lower than the external maximum water level. There is air present. The people who evade these places have the conditions for survival. If the evacuation method is correct (the mood is calm, the right amount of water, lying down to be saved) is able to survive. On May 20, 1998, the groundwater rainfall in the Zhuozishan mining area in Wuhai, Inner Mongolia Mu coal mine production, the 13 people were trapped underground, including a human Escaping survived 34 days in the downhole well. Many examples like this show that after a water inrush accident, some locations have people's living conditions, and even if they dodge for a long time, they will not survive. For those places of refuge that are lower than the external water level, drilling is strictly prohibited to prevent the leakage of the single head air, the water level rises, and the people in distress are overwhelmed. The best way is to speed up the drainage, that is, rescue them as soon as possible.

As a rescuer of water permeable accidents, it is also necessary to grasp the living conditions of the trapped people in the underground and the precautions for ambulance:

1. Air conditions for the survival of underground asylum seekers:

According to scientific analysis and a large number of cases, under the following conditions, the risk-aid personnel have the possibility of survival: 02 ≥ 10%, C02 ≤ 10%, CO ≤ 0.04%, H2S ≤ 0.02%. NO: <0.01%, S02

2. Food conditions for the survival of underground asylum seekers:

In addition to the air, people need food. After the water inrush, the people in distress are lack of food. They rely on drinking water, squatting wood, cotton coats, coal blocks, wires... to maintain their lives. In fact, these things have no nutritional value. Can not be absorbed by the body, but can not be digested at all, can only support the stomach to eat, reduce the pain of hunger. Water is an important part of the human body, and 78% of the human body is made up of water. Although water has no nutritional value, when people are fasting, drinking water can promote metabolism and consume sugar and protein stored in the body to maintain the body's energy supply. A trapped person must have water and air to survive for a period of time. According to reports, the longest time in the world to survive by drinking only water is 58 days.

3. Precautions when salvaging long-term trapped underground personnel: Practice has proved that when people who have been trapped for a long time are rescued, if they do not take corresponding measures, the survivors will also die. When salvaging people who have been trapped for a long time, it is forbidden to illuminate their eyes with light (to make the light beam avoid their eyes, or to cover the light with a red cloth, a piece of clothing to make the light weaken; or to cover their eyes with a cloth) ), maintain body temperature, perform physical examination and give necessary treatment (dressing, infusion, etc.); can not immediately lift out the wellhead, should be transported to a safe place in stages, let it gradually adapt to the environment; can not eat hard food and excessive food, so as not to damage digestion System; don't let your relatives and friends visit in the short term, so as to avoid excessive blood flow and rupture of blood vessels.
