采用截割实验系统对采煤机截齿截割煤岩进行了模拟实验，得出了刀形、镐形两种截齿截割过程中有关参数的变化情况，为采煤机截齿的设计及使用提供了实验依据。
The cutting experiment system is used to simulate the cutting of coal and rock in shearer’s pick, and the change of relevant parameters in the cutting process of pick and pick are obtained, which is the design of shearer’s pick And provide experimental basis for use.
