前言 Teale[1]提出的比能(S、E)概念,可作为估计岩石可钻性的一种快速方法。Teale把比能定义为:破碎单位体积岩石所需的能量。可是在文献[2]中又提出了依据新表面积产生的另一比能定义。
Preface The concept of specific energy (S, E) proposed by Teale [1] can be used as a quick method to estimate the drillability of rocks. Teale defines specific energy as: the energy required to crush rocks per unit volume. However, another specific energy definition based on the new surface area has been proposed in [2].
