冲击式采掘机械工作机构的研究

The study of pick mining machine operating mechanism

目前我国多数采掘机械的工作原理是使岩体产生的压、剪破坏,而冲击式采掘机械则是通过冲击波的传递,在岩体表面产生拉应力,从而使岩体发生拉伸破坏,这里给出了冲击式采掘机械截齿的安装角及冲程的设计方法及计算公式。

The Operating principle of the most M ining Machine used in China is shatte ring the rock mass by compression and shear stress,Pic k mining machine bracking the rock ma ss by the hemicontinuous of blast wave which can cause tensile stress o n the surface of the rock mass.Both of the design methodology and cal-culation formula for the setting angle and stroke were given in this artic le.
