Metal mines in the country, or the upper vein deposits buried deposits above the ground level, to develop multi adit. When the ground is a hilly area or the terrain is relatively flat, the deposits buried below the ground are often selected for development. In the early days of the founding of the People's Republic of China, due to the low degree of mechanization and technical level, the technical equipment and construction technical requirements for tunneling inclined wells were lower than those of vertical shafts. Therefore, some small and medium-sized mines used inclined wells to develop. With the mechanization degree and the level of construction technology, and the shaft has better lifting capacity than the inclined shaft and good safety, the new mines often use shaft development. However, with the emergence of long METIC rope belt conveyor, some domestic coal mine inclined shaft, which is incorporated in the transport of coal, successful experience. After the metal mine was crushed underground, it also began to transport the ore in a diagonal well using a copper wire rope conveyor. Some large and medium-sized mines in foreign countries have installed high-strength long-distance wire rope belt conveyors in inclined shafts or ramps to transport ore through the ground exit to select plants, from intermittent transportation to continuous transportation, and the production capacity has been significantly improved. Some small and medium-sized Laoshans in foreign countries have installed new types of buckets in inclined wells. The fractional section upgrades the ore from various stages, and the equipment is simple, flexible and efficient. It can be seen that the use of inclined wells has a certain development prospect. At present, mines at home and abroad use a single ramp as the main roadway, and there are very few mines. Most of them use slopes as auxiliary roads to develop roadways and cooperate with other major roadways for development.

Mines mainly develop the choice of roadway type
The main types of roadway development are mainly selected according to the topography of the mine, geological conditions and the occurrence conditions of the ore body.
