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。 | | 5. | Abstract : because the kinds , structure , storage and stratification of coal are different , it is difficult to analyze the effect factor on coal cutting power . based on a lot tests , the change rule of cutting parameter with cutting power is discussed , it is an important basis for designing , researching and selecting mining equipment , prcessing and technical reform
