摘要
在实验室对采煤机截割煤岩过程进行了模拟实验,并对截割过程进行了散斑测试,发现截齿截割中存在局部化变形的规律,这一实验结果对认识煤岩截割机理具有重要意义。
By simulation test of coal/rock cutting process in laboratory, the speckle measurement of cutting process was done. It is found that there is localization law during pick cutting. The experimental result is very useful for understanding the mechanism of coal/ rock cutting.
