Because I don't know how big the mine is, when the support frame in the mine collapses, it is easy to collapse and fall into the mine in case of earthquake or rainy weather.
02: Because the mine is deep and has a long history, there may be toxic gas in the engine room. After years of accumulation, various chemical gases will be emitted from the mine, some of which may be deadly toxic gases; The engine room is sealed for a long time, and once the engine room door is opened, high concentration of toxic gas may be inhaled.
03: The cabin is in disrepair. Although the hut can be preserved for decades, it can't bear to be invaded by nature for many years. If the door of the engine room is opened, the overall structure will change and shift, and there is a risk of collapse and injury at any time.
04: It has long been occupied by animals. Some cabins are abandoned by local people instead of mines. Some animals will "occupy the magpie's nest" and directly regard it as their own residence. If so, they will be easily attacked by wild animals.
05: There are many traps around the wooden house, because there are wild animals in the forest. In order to prevent these animals from approaching residential areas, villagers will set many traps next to wooden houses.
06: Private Houses of Local People Except for the above five situations, wooden houses are the private property of local people, and some people don't want outsiders to disturb them. If you break into a private house, the local law allows the owner to do some acts of self-defense.
The above points are the reasons for traveling to Russia. Why can't you get close to the cabin in the forest at will? If you can go to the cabin outside the forest, you'd better ask in advance.
To sum up, no matter where you travel, especially in some strange countries and regions, you should do your homework in advance and obey the arrangement of the tour guide, so as not to cause unnecessary trouble and lose more than you gain.
