The wall-cutting method is mainly used to mine extremely thin ore bodies that are steeply inclined, and is also used to mine gently inclined ore bodies in individual mines. When mining steeply inclined veins, they can be divided into two schemes: manual mining and mechanical transportation according to the different methods of ore transportation in the stope. Most mines currently using such mining methods in China still use manual mining schemes, and only small electric rafts and small scrapers are used to transport ore in individual mines. The typical scheme is shown in Figure 1.

When mining gently inclined veins, according to the different working face forms, the following schemes can be divided into: the inclined working face cutting wall filling method and the walking wall wall cutting filling method.
The typical scheme of the gently inclined wall filling method is shown in Figure 2.
