| 中文摘要:通过分析压入硬度和破岩比功的关系，得出比功更能综合反映岩石的破碎难易程度的结论。为简化比功的测定方法，提出根据压入硬度、塑性系数及破碎坑体积扩大率来估算比功的方法，推导出比功的计算公式，并对比功的计算值和实测值进行了对比，具有一定应用价值。 |

| Abstract:Based on the analysis of the relationship between the indentation hardness and the rock destruction specific energy, it is concluded that the specific energy gives a more comprehensive indicator of rock destruction difficulty To simplify the measurement of the specific energy,a specific energy estimation method based on the indentation hardness, plastic co efficient and volumeric expansion rate of the indented crater is put forward with the calculation formulae of the specific energy derived, and a comparison is made between the calculation values and the actual measurements, which indicates some practicality |
