The bottom hole yard is connected with underground transportation and wellbore lifting, and the ore, waste rock and decentralized materials and equipment are transported through here. Therefore, it is necessary to arrange storage lines, shunting lines, bypasses, etc. near the wellbore. In addition, the bottom hole yard also serves lifters, drainage and ventilation, so correspondingly some diverticulum should be adjusted near the wellbore, such as pump house and water tank, and underground substation. The bottom hole yard is the general term for these roadways and diverticulum.
According to different development methods, the bottom hole yard can be divided into two types: vertical shaft bottom yard and inclined shaft bottom bottom yard.
