Abstract: Abstract：The research and application of intelligent dry separation system in coal mine is the practical action and important mean on accelerating the construction of intelligent mines in China. In order to explore the layout method of intelligent dry separation system, The basic principle, key technology and main advantages of intelligent dry separation technology are introduced in detail, Two layout methods of underground intelligent dry separation system were put forward and introduced in detail by the engineering design case, which include the layout method of transfer point at the end of the main roadway and the layout method of the middle part of the main roadway. On this basis, The upgrading method of ground washing system is put forward In view of the problems faced by many coal mines, such as high labor intensity and low work efficiency of manual separation, which further expand the applicability of the intelligent dry separation system. Through the systematic research on the layout method of intelligent dry separation system, the design system of intelligent dry separation system is improved, which lays a foundation for the popularization and application of intelligent dry separation technology and the construction of intelligent mine.
