Deep well rescue method in mining

Yantai Aopu Mining Machine answers the rescue measures for mining deep wells for you. The specific operation is as follows:

(1) site reconnaissance

After the rescuers arrive at the scene, the first task is to conduct on-site reconnaissance. The specific reconnaissance contents are as follows:

(1) Ask about the time, reason, number, age, gender and other natural conditions of the people who fell into the well, and call out to the underground in time to see if anyone responds.

(2) Determine the wellhead size, well depth, whether the borehole wall is in danger of collapse, whether there is water and toxic and harmful gases underground through external observation and internal personnel inquiry.

(3) For more complicated deep wells, the position and state of underground personnel can be judged by "snake eye" life detector and other equipment. For complex municipal deep-well pipelines or engineering wells in factory mining areas, municipal management and design departments and units should be required to provide the design network diagram of deep-well pipelines in time to understand the layout, trend and structure of deep-well pipelines.

(2) Rescue preparation

(1) First, fresh air or oxygen should be provided underground. Blow air into the well through a blower or a range hood, or hang several open-air respirator bottles underground, and use a mobile air supply source to make people trapped underground breathe air to prevent people from choking.

(2) Put a rope into the well as much as possible to fix the person who falls into the well to prevent him from falling further. If the person who falls into the well is young, you can hook the person who falls into the well with a fire hook or one end of a steel bar, so that he can save his strength and wait for rescue.

(3) According to the specific situation of the site, the warning zone shall be defined in time and the warning line shall be set up. Rescue workers should be grouped, grouped and set up a reserve team. At the same time, too many wellhead personnel should be avoided, which will cause the borehole wall to collapse and cause secondary injuries to those who fall into the well.

(4) If there is water in the well, you can pump it out with a water pump to lower the water level in the well and prevent people who fall into the well from drowning below the water surface. If there are toxic and harmful gases underground, smoke exhaust equipment should be fully used to reduce the concentration of harmful gases.

(5) The safety officer should check the respirator pressure, safety rope, safety belt and other equipment, determine the fixed point of safety rope, and make records.

(3) Saving lives and eliminating risks

(1) If the person who falls into the well is not injured or awake, he should quickly use ropes or other lifting equipment to carry out rescue and directly lift.

(2) When it is found that the person falling into the well is injured or in a coma, the correct rescue method should be chosen to rescue him from the well after confirming that there is no possibility of collapse or danger of secondary injury.

(3) When the wellhead is too small, people can't get down or have collapsed, we should quickly mobilize social linkage forces, and use excavators or pile drivers to dig tunnels or drill wells from the side to save lives.

(4) On-site first aid and clean-up handover

After the rescue is completed, the survivors should be given medical assistance as soon as possible and sent to the hospital for treatment in time; If the rescued person is confirmed dead by the on-site medical staff, he shall be handed over to the public security organ for handling.

Safety protection measures for underground rescue

Underground rescue is an extremely dangerous rescue operation. Only by doing a good job in the safety protection of rescuers and rescued people can we truly achieve "scientific rescue and foolproof".

(1) Before carrying out underground rescue, it is necessary to find out the actual underground situation and confirm whether the deep well will collapse. Rescuers must wear breathing apparatus and safety ropes.

(2) During rescue, it is necessary to prevent the respirator mask from falling off or the gas supply pipeline from being damaged, threatening the safety of rescuers. The personnel around the wellhead should be few and skilled, so as to avoid stepping on the wellhead or dropping articles, which may cause danger. If a triangular rescue bracket is used, it must be checked whether the fixation is firm.

(3) When excavating, there must be safety observers to observe the rescue situation at any time. On the one hand, it is necessary to prevent the excavator from damaging the shaft wall and threatening the people who fall into the well. On the other hand, after digging to a certain depth, it is necessary to avoid landslides and reinforce steep slopes in time.

For all kinds of underground rescue sites, due to the different actual conditions, fire rescue personnel should take the attitude of concrete analysis of specific problems, fully integrate existing equipment and equipment, and complete the rescue task under the condition of ensuring safety. When an accident occurs, the conditions for rapid evacuation must be met.
