摘要
在实验室条件下所做的截割试验，得出了在不同截割对象、不同工作参数下，刀形截齿的截割阻力及其变化规律。这对于研究刀型截齿的截割性能和正确地选择与合理地使用刀形截齿具有重要意义。
By cutting experiments in a laboratory,the cutting resistance and their varying regularities of flat pick on different coal and rock specimens, under different working parameters are found, which has important bearing on further studying cutting performance, correctly selecting and reasonably using the pick.
