Cave Exploration Notes

1. 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 rock, volcanic rock, limestone, etc., whether there are earthquakes and other activities, and see if the geological institution is in danger of roof fall, Be aware of it.
(2) Is there a resting spring in the cave? If there is a sudden flood in the cave, I think it is not just a joke. 3. Is there any dangerous gas in the cave? Generally, deep non-permeable caves may contain dangerous gases such as methane and gas due to the long-term air circulation. Therefore, it is absolutely necessary to bring a mine gas detector.
(3) Whether there are dangerous animals in the cave, such as poisonous snakes, spiders, or other insects, it is indispensable to bring some necessary medicines.

2. Prevent getting lost

Getting lost in the cave can be fatal. Therefore, it is absolutely helpful to develop the ability to distinguish directions, mark along the way, and the habit of drawing a map of the cave yourself. The specific method of drawing a map can also use a compass.
The method is: take the hole as the starting point and make a starting point on white paper, mark the advanced direction and the north line, and then use the footsteps to roughly record the distance. Of course, you can also make a footstep recorder that changes in the terrain (such as crossroads). , Turn, etc.) Then mark it on the paper according to a certain proportion and record the current point and the direct line of the next direction and the north line. Do this in turn, and you can have an adventure map.

3. About the mark

You can mark the place where the route of the hole changes according to your habit on the way forward. In addition to marking your coming and going direction, it is best to mark the cave in order. It is best to use a straight tube. 20 liters PVC heat-pressing waterproof bag; equipment bag, rope bag should use PVC straight bag with drainage net. , So that you can find a way out more easily when you come back.

4. About the lighting used in cave exploration

Generally speaking, there is no light in the cave, so we must be fully prepared. If there is no light in the cave, it will be hard to move. Fear and helplessness will quickly destroy your team. You can no longer make correct judgments and actions, so I suggest that you have sufficient lighting equipment. Explosion-proof headlamp for helmets are a good choice. Bring as many spare batteries and light bulbs as possible. Each team member should bring them. When using it in turns, don’t turn on all the lights to save power. In addition, the Blight (B: I don't know how to type on the keyboard) is also a very good tool. For determining the position of the players in the hole, checking the time when camping, the map is a very good tool.

Equipment required for cave exploration

1. Clothing:

Consider the local climate, temperature, and water temperature in the cave, and take lightness and simplicity as the principle. There is no need to consider the waterproof of the clothing too much, because the humidity in the cave is close to saturation, and the waterproof fabric will hinder the rapid discharge of sweat and heat. You can use a TC coverall that is both wear-resistant and perspirable. The bright colors of the clothes are conducive to the identification.

2. Shoes:

solid and high-quality high-tube plastic work boots, which are rarely seen in ordinary domestic stores. Foreign trade work boots and fire-fighting boots can be considered; in case of wading, diving socks can be added to keep warm. Hiking shoes cannot fully adapt to the complex geological conditions in the cave.

3. Helmet:

a professional adventure helmet should be used.

4. Backpack:

Carrying personal belongings and tools should choose a backpack with a sealed and waterproof roll-up mouth. The material is preferably PVC.

5. Lamp:

Headlamp is the first choice, and the continuous working time of a single power supply should be more than 8 hours. The power of the LED light should be greater than 1 watt, and the illuminance of other light sources should be above 300 lumens, the brighter the better. At the same time, you should carry a backup battery and 2 sets of backup lighting every time you enter the hole.

6. Rope:

lead the way or the main rope according to the situation. Flat holes generally require more than 30 meters of rope for roads and shafts. Depending on the situation, the rope should be doubled to the estimated depth. 7SRT: A general term for technical equipment that uses a single rope to move safely on any terrain, including ascenders and descenders, seat belts, oxtails, and feet,The pedals and several locks require training and constant practice to master them.

7. Food and water:

Vacuum packaged food is the first choice. You should bring: food that is longer than the planned time, so try to choose high-energy compressed food! Reduce the load. Water should be carried 15 times the planned amount. Water sources can often be found in the caves, and you can drink them in emergencies. If the quality is bad, you can bring a water purifier. If it is a cave in an arid area, you should bring 2 times or more water.

8. Others:

life jackets and floating rafts, small waterproof bags, compasses, notebooks, and pens should be considered for water caves.

Common sense of precautions for wild expedition

1.Don't camp near the swamp.

2.Be sure to use mosquito nets.

3.Take fewer clothes off.

4.The raised bed is at least 1 meter above the ground.

5.A lighted cigarette can loosen the mouth of many insects that bite the flesh.

6.Put a tourniquet first after a poisonous snake bite, and then detoxify. If the hand and foot are bitten and cause swelling, the upper limb person punctures the Baxi acupoint, which is between the four fingers. The lower limbs punctured the Bafeng acupoint, that is, between the four toes. To speed up detoxification and swelling. Puncture method: Use a thick needle with a blunt needle to puncture straight into 2 cm.
