In order to improve safe operation of mine hoist and according to low automation degree, poor reliability and safety, design scheme of mine hoist control system based on PLC variable frequency control was proposed, whose core was Sanling FX2N programmable controller. Precise control of mine hoist was realized by general purpose converter. As a result, hard maintenance, short service life and high energy consumption of elevator control systemwere improved, safe, stable and reliable operation of coal mine hoist was achieved. The result showed that this technology had high promotion value.
