摘　　要：因液压技术单位质量输出功率大,现在许多薄煤层采煤机都采用液压牵引系统,如何提高液压牵引系统的工作可靠性,减少井下维护次数,显得十分必要,从3个方面提出改进措施。At present, the hydraulic haulage system are employed by most thin miners because output of hydraulic technology unit mass is powerful, it appears very necessary that how to improve hydraulic traction system reliability,reduce maintenance times in a coal mine. Three improving measures are given in the thesis.
