Detailed explanation of matters needing attention in cave exploration

Outdoor exploration is a sport to test our survival ability in the wild, and cave exploration is a challenging outdoor activity. We must recognize the precautions of cave exploration in order to better complete the cave exploration activities. The following is a detailed introduction of the matters needing attention in cave exploration that I have compiled for you, hoping to help you.

Precautions for cave exploration

I. Security issues

1. Before specific actions, you should have a certain understanding of the geological structure of the cave or the area where the cave is located, such as sedimentary rocks, volcanic rocks, limestone, etc. Whether there are earthquakes and other activities depends on whether the geological institutions are in danger of roof caving, so as to know fairly well.

Is there a geyser in the cave? If the tunnel suddenly floods, I think it will be more than a joke. 3. Is there any dangerous gas in the hole? In general, due to the long-term circulation of air, there may be dangerous gases such as methane and gas in deep impermeable holes. Therefore, it is absolutely necessary to bring a mine gas detector.

Whether there are dangerous animals in the cave, such as poisonous snakes, spiders or other insects, it is essential to bring some necessary medicines.

Second, prevent getting lost.

Getting lost in a cave can be fatal, so it is absolutely helpful to develop the ability to identify the direction and the habit of marking along the way and drawing a map of the cave yourself. The specific method of drawing a map can also use a compass.

The method is: start from the mouth of the cave, make a starting point on white paper, mark the direction of progress and the northern line, and then roughly record the distance with your footsteps. Of course, you can also make a footstep recorder, and record the current point, the direction line and the north line in the next direction on paper according to a certain proportion, and do this in turn, and you can have an adventure map.

As for marking, you can mark the place where the route of the hole changes according to your own habits on the way forward. In addition to marking the direction where you came and the direction where you went, it is best to mark them in order, so that it is easier to find a way out when you come back.

Three. Lighting used in cave exploration

Generally speaking, there is no light in the cave, so we should be fully prepared. If there is no light in the cave, you will be unable to move, fear and helplessness will soon destroy your team, and you will no longer be able to make correct judgments and actions.

Therefore, I suggest that there should be sufficient lighting equipment, miner's lamp is a good choice, spare batteries and light bulbs should be brought as much as possible, and each team member should take turns to bring them when using them, which will save electricity.

In addition, b light (b:? White him? I don't know how to type on the keyboard) is also a good tool. Maps are a good tool to locate players in caves and check the time when camping.

Fourth, the equipment needed for cave exploration.

1. clothing: considering the local climate, air temperature and water temperature in the cave, it is light and simple, and it is not necessary to think too much about the waterproof property of the clothing, because the humidity in the cave is close to saturation, and the waterproof fabric will hinder the rapid discharge of sweat and heat. Wear-resistant and breathable one-piece clothing made of TC can be used. Bright colors help to identify clothes.

2. Shoes: Strong and high-quality plastic work boots are rare in ordinary shops in China at present. Foreign trade work boots and fire boots can be considered; In case of wading, you can wear diving socks to keep warm. Hiking shoes can't fully adapt to the complex geological conditions in caves.

3. Helmet: You should choose a professional adventure helmet.

4. Backpack: It is advisable to choose a backpack with a sealed waterproof roll for carrying personal belongings and tools, made of PVC mesh. The straight 20-liter PVC hot-pressed waterproof bag should be used to explore the hole; Equipment bags and rope bags shall be PVC straight bags with drainage net.

5. Lighting: headlights are preferred, and the continuous working time of single power supply should be more than 8 hours. The power of LED lamps should be greater than 1W, and the illumination of other light sources should be above 300 lumens. The brighter the better. At the same time, you should carry spare batteries and two sets of spare lighting every time you enter the hole.

6. Rope: approach rope or main rope according to the situation. Generally, a tunnel with a rope of 30 meters flat enough; According to the specific situation, the shaft needs more ropes, and the depth is twice as deep as expected.

7.SRT refers to the technical equipment that can move safely in any terrain with one rope, including lifting device, safety belt, oxtail, pedal and several locks. Mastering it requires training and constant practice.

8. Food and water: vacuum-packed food is the first choice, and the time you carry food is twice as long as planned, so try to choose high-energy compressed food to reduce the load. Water should carry 1.5 times the planned amount. Water can often be found in caves and can be drunk in an emergency. If the water quality is not good, you can carry a water purifier. If it is a cave in an arid area, you should bring more than 2 times of water.

9. Others: life jackets, floating rafts, waterproof bags, compasses, notebooks and pens should be considered in the water tunnel.

Common sense of matters needing attention in field exploration

1. Don't camp near the swamp.

2. Be sure to use mosquito nets.

3. Take off your clothes less.

4. Set up a bed at least 1 m above the ground.

The lighted cigarette will make many insects bite off the meat.

6. After being bitten by a poisonous snake, put a tourniquet first and then detoxify. If the hands and feet are bitten and swollen, the upper limbs will stab the Eight Evil Points, that is, between the fingers of four fingers. The lower limbs puncture Feng Ba point, that is, between the four toes. In order to speed up detoxification and reduce swelling. Puncture method: Puncture 2 cm with blunt needle and thick needle.

Case: The backpacker in Lop Nur was killed.

The early winter in Rob's wasteland is quiet and monotonous. Even in the marginal town of Milan, few people are willing or dare to go deep into the desert for a few miles. However, in June 65438+February 65438+June last year, a little boy who was grazing reported an amazing news to the Milan police station: he found a body on the Gobi desert near the ruins of Milan!

After receiving the news, the police of Milan police station came to the scene of the accident and saw a man die in a tent. His body is in a natural state with vomit in his mouth, no obvious scars and no signs of struggle. The police didn't find any clues to prove his identity in the tent, and there were no valuables such as cameras. There were only two tickets for 165438+ 10.

Without the intervention of outsiders, this backpacker, like many unknown explorers killed in the mysterious Lop Nur, stayed away from his relatives and fixed his life on this wasteland forever.
