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。
Due to the difference of coal types, structure, occurrence and bedding, it is difficult to analyze the factors influencing coal cutting force. On the basis of a large number of experiments, the variation of cutting force with cutting parameters is discussed, Select mining equipment, mining technology, technological transformation provides an important basis.
