Mining is divided into open-pit mining and underground mining. The mining of township and township enterprises in China is the largest in the mining of barite ore. It is mainly open-pit mining, mainly mining residual slope deposits, and outcrops and shallow parts of ore bodies. For example, the Tanzishan barite mine in Hengnan County, Hunan Province is a state-owned old enterprise that was put into operation in 1958. It has four mining areas, one exposed mining, three underground mining (inclined wells, flat rafts), and an underground mine in the 1980s. Closed pit, another underground mine closed due to flooding in the vicinity of the people. Open-pit mines are also unable to keep up with the stripping, mining and slope instability, which affects normal production. Underground mining, filling method, stage caving method, etc. have been adopted. The main mining equipment in underground mining is hand-pushing rubber wheel, 300kW hoist for inclined shaft, local fan for ventilation, wood support and concrete support for underground support. The open pit mining is mainly equipped with loaders and 4t dump trucks.
