Disadvantages of connecting straight wells to dig caves

1, high security risk. Connecting the shaft to dig the cave needs to be carried out underground, which has potential safety hazards such as collapse, water seepage and toxic gas accumulation, and is easy to cause accidents.

2. Poor air circulation. Connecting vertical wells to dig caves will affect the air circulation in caves and easily lead to insufficient oxygen, thus affecting the health and safety of workers.

3. Impact on the environment. Connecting vertical wells to dig caves needs to be carried out underground, which will have an impact on groundwater, soil and other environments and have a certain negative impact on environmental protection.
