摘要
依据煤体中冲击应力波的传播规律 ,对冲击式采煤机的冲劈厚度、刀齿密度、冲击频率、刀齿强度等参数之间的函数关系 ,以及同煤炭本身物理力学性质之间的关系进行了研究。为改进和推广现有的冲击式采煤机提供了必要的理论依据。
Based the mechanism of coal and rock breaking by impact,and the rock breaking study,study the authors the parameters of impact mining machine,the functional relationship of the split thickness of impact,the density of impact tools,the impact frequency and the relationship between these parameters and the coal mass property.These findings will provide the necessary theory dependence for optimizing design and popularizing use of theimpact mining machine.
