摘　　要：研究了冲锤直接撞击凿岩的动力学特性,并运用能量守恒原理分析了在这种撞击下的凿入效率。当冲锤具有足够大的截面面积时,即可获得接近于1的凿入效率。因此,这是一种新的基于这种撞击特征的岩石凿入系数的测量方法。The dynamics characteristics of the hammer＇s impacting directly rocks have been studies in this paper, and the efficiency under this impact has been analyzed with the principle of energy conservation. The drilling efficiency is near 1 when the hammer has a enough big sectional area. So this is a new measuring method for the drilling coefficient based on this impact property.
