Abstract:

In shoushan mine, many problems that exist in the use of hydraulic winch mine effect coal mine normal production,but along with the use of frequency conversion winch, the failure rate of winch sudden drop and the apply obtains good results.furthermore these application of frequency-converting technique in some equipments such as compressor、partial fan has bring about the goal of high-yield、high-efficient、low-energy、low-cost in coal mine.

Key words: frequency conversion winch, the inclined-tunnel's lifting, apply
