Abstract Mine hoist is an important auxiliary transportation equipment in the current coal mining operation. The JKY-2.0/1.8 hoist of Xingyu Coal Mine adopts the traditional control mode, which is not intelligent and inefficient. In order to effectively improve the working efficiency and reliability of the mine hoist, it is decided to carry out technical transformation of its control system. Based on PLC and frequency conversion technology, the control system of JKY-2.0/1.8 hoist in Xingyu Coal Mine is improved, and the speed of hoist in actual operation is controlled by frequency conversion. The application effect of the reformed control system is good, the working efficiency of the hoist is obviously improved, the equipment runs smoothly, and the ideal economic benefits are obtained.
