采[截]煤。
Examples
- Drill bit for coal cutting
电煤钻头 - An improved mode of coal cutting is recommended aiming at the specifical status of surface collapse of coal field in yanzhou city , and several control policies on restoration and reclamation of collapsing land are also put forward
针对兖州矿区的具体塌陷状况提出了改进采煤方式、对塌陷土地进行恢复和复垦等几点防治措施。 - 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
由于煤炭的种类、结构、赋存和层理的不同，给分析影响煤炭切削力因素带来了困难，在大量实验的基础上，讨论了切削力随切削参数的变化规律，为设计、研究、选择采掘设备、开采工艺、技术改造提供了重要依据。 - 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。 - 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
