| | 4. | The results indicate that a stable deformation localization band occurs in the coal cutting course and develops to macroscopic crack ; the deformation localization band is slantwise ; while the cutter tooth is used , the deformation localization develops slowly , and the localization becomes wider and the strain value in the band area higher afterwards ; when the point - attack pick used the localization develops quickly and the localization band becomes narrow and the strain value in the band lower
研究表明：截齿截割煤体过程中，煤体出现稳定的变形局部化带，且最终发展为宏观裂纹；煤体变形局部化带为一个倾斜带：刀齿截割时，变形局部化发展较慢，但产生变形局部化后，局部化带宽且带内应变值较高；而镐齿截割时，变形局部化发展较快，但产生局部化后，局部化带窄且带内应变值不如刀齿高。

冻煤破坏是拉应力破坏,在此基础上建立了冻煤的切削模型,根据最小能量原理得到截割力,进给力和截齿间距的计算公式,分析得到截割力与切削厚度成正比,随着前角的增大而减小;截齿最优截距与截齿尺寸有关且与切屑厚度成正比;进给力随着截齿前角增大而增大的规律。
