【摘要】 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。更多还原

【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.更多还原
