How was the cave exploration?

Cave exploration, also known as cave exploration, is an outdoor sport that combines science with sports and tourism to satisfy people's curiosity, and it is also an exciting activity. During the cave exploration, each member should concentrate on completing his part of the exploration task, and at the same time, he should independently put forward various emergency measures so that he and his companions can safely and smoothly save the day. The "independently" mentioned here not only contains rich knowledge, superb and comprehensive hole-exploring technology and perseverance!

From the point of view of getting in and out of caves safely, cave exploration can be divided into two types: water cave exploration and dry cave exploration.

exploration of water caves: water caves refer to karst caves with perennial underground water flow. There are two kinds of exploration in water caves.

one is that there is a free water surface in the underground corridor.

in one case, the tunnel has no roof and is completely filled with water or inverted with straws.

dry hole exploration. Dry cave is a fossil cave that is out of the free water surface. It develops in a higher place with a long history, and the cave is often decorated with various kinds of stalactites.
