摘要
以煤炭截割强变、脆性、破碎性几个特性指标为对象，探索了煤炭截割阻力影响因素，对煤的脆性程度、截割时破碎性进行了评价，为采煤机械的设计计算、选型应用、发挥机器最大效益，提供了理论依据。
The paper which is dominated by mining operation features, such ascoal-cutting strength, brittleness and breakage highlights the analysis of thefactors involving coal operation resistance. The evaluation is made of the brittleness andbreakage. The paper features the theoretical basis for the design and calculation, modelselection and application and the fullest scope of the efficiency of mining machines.
