Abstract： gas drainage is the mostly measure for gas disaster prevention and cure radically , and pipeline resistance calculation is the precondition for gas drainage design and parameters optimization , however some errors are obviously between theory calcula-tion andlocal testing at present.In order to analyze the friction resistance characteristics of drainage pipeline and optimize calcula -tion method, the essence connotation and main affecting factors were discussed according to hydrodynamics Darcy 's law and di-mensional theory, and the deficiency of actual Calculation Method was pointed out , and optimization method was set up.Basing on above-mentioned analysis, optimization method was applied to scene practice contrasting primary .The results showed that optimized method was accordant with the testing with comparative error 0.6%merely.
