  1. 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：截齒截割煤體過程中，煤體出現穩定的變形局部化帶，且最終發展為宏觀裂紋；煤體變形局部化帶為一個傾斜帶：刀齒截割時，變形局部化發展較慢，但產生變形局部化后，局部化帶寬且帶內應變值較高；而鎬齒截割時，變形局部化發展較快，但產生局部化后，局部化帶窄且帶內應變值不如刀齒高。
  2. Based on the cutting experiments used by cutter tooth and point - attack pick on the press and cutting simulation test table, the deformation and failure process of coal body are studied by the method of white light digital speckle correlation

    摘要採用白光數字散斑相關測定方法，在壓力機上，在截割模擬實驗臺上分別對煤試件進行刀齒、鎬齒的截割實驗，研究被截割煤體的變形破壞過程。
