摘要： 以掘进机伸缩结构设计为对象，聚焦悬臂式掘进机，在对其进行综合论述的基础上，对悬臂式掘进机伸缩臂
结构及其不足进行综合分析，继而开展悬臂式掘进机伸缩臂结构优化探究，希望能够为其他矿井掘进机伸缩臂改良优化
提供帮助和借鉴。

Abstract: Taking the design of the telescopic structure of the roadheader as the object, focusing on the cantilever roadheader,
based on a comprehensive discussion of it, this paper carried out a comprehensive analysis of the structure and shortcomings of
the telescopic boom of cantilever roadheader, and then researched on the structural optimization of telescopic boom of the cantilever
roadheader, hoping to provide help and reference for the improvement and optimization of the telescopic boom of other mine
roadheaders.

Key words: mine; roadway driving; cantilever roadheader; telescopic boom
