摘　　要：以滚筒采煤机截割头为研究对象,建立截割头常见故障树,采用FTA对其展开深入分析,得到了造成截割头失效底事件。将这些底事件进行分类汇总,收入煤机制造企业FMEA管理体系中,通过FMEA程序,对这些底事件逐个予以改进或根除。生成FMEA工作表,送达企业相应部门执行,提高采煤机的可靠性。The cutting head of drum shearer is used as the research object,creating the fault tree of cutting bead＇s common faults,exploring the bottom events of those failures.Then classifying these events, putting them into the coal machine manufacturing enterprise＇s FMEA management system, improving or eradicating them by the FMEA program.Generated FMEA worksheets, delivered to the relevant departments to executing,improving the reliability of drum shearer.
