The utility model relates to an automatic-control high-emulation practical training device for a multilevel main drainage system for a mine, which belongs to the technical fields of mine technical training equipment. The adopted technical scheme is that the practical training device comprises a main framework (1), a control panel (2) on the main framework (1), an electrical control part (4), a 600 drainage system, a 600 horizontal simulation water tank (3), a 400 drainage system, a 400 horizontal simulation water tank (10) and a lower water tank (8), wherein the 600 horizontal simulation water tank (3) is communicated with the 600 drainage system; and the 400 horizontal simulation water tank (10) is communicated with the 400 drainage system. The practical training device has the benefits that a miniature design is adopted, and the system structure, working principle, control function and the like can be visually and really demonstrated; and in addition, the operation, control, fault emergency, innovation and other functions of the multilevel main drainage system can be performed on the automatic-control high-emulation practical training device.
