• 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。
