Based on disadvantages of speed regulation of coal belt hydraulic coupler in coal mine main belt including high current, synchronization control difficulty and higher equipment wear rate, working principles and advantages of frequency conversion technology were discribed. The advantages and disadvantages of hydraulic coupler and variable frequency speed regulation in control of speed regulation of coal mine belt transportation system were compared, the result showed that variable frequency speed control technology had good adaptability. Taking the mine belt transport system of a mine in Shanxi as an example,practical application of frequency conversion speed control technology was analyzed.
