Abstract: The hoist is an important guarantee for the effective development of mine production, and its operating efficiency has a
direct impact on the comprehensive benefits of the mine. Taking this as a starting point, the design of the dual PLC speed regulation
system of the underground hoist was discussed. Combined with the actual project, on the basis of analyzing the control principle
of the dual PLC speed regulation system, this paper elaborated the hardware design, anti-interference design and software
design of the system, hoping to provide reference for the construction of similar systems in other mines.

Key words: mine; hoist; frequency conversion speed regulation; dual PLC; system design
