The wellbore for lifting ore and the flat and sloped roads for transporting ore are called main development lanes. In the non-coal mining, the auxiliary roadway, such as auxiliary shaft, wind shaft, filling well, bottom hole yard, Shimen and stage transportation lane, is called auxiliary auxiliary roadway.
The mineral deposit development method refers to the type of main development roadway that develops mineral deposits, which can be divided into two categories: single development method and joint development method. The single development method is to use a main development lane. The road is developed by the joint development method . The joint development method is to use two kinds of main development roadways to develop mineral deposits. Usually, the shallow part of the deposit is developed with a main development roadway, and the other part is developed with another main development roadway.
