一、岩石的特点、物理力学性质及分级由第一、二讲已知,研究了不同的破岩方法,其目的都是为了破碎岩石的;凿岩是破碎岩石的一种特殊形式;不同方式的钻岩法适用于不同性质的岩石破碎;等等。因此大概地了解凿岩机械的工作对象——岩石的特点、有关物理机械性质以及与凿岩有关的岩石分级,对我们研究探讨以及选用凿岩机等方面可能都是有利的,因此下面作简要介绍。
First, the characteristics of rock, physical and mechanical properties and grading From the first, second, known, studied a different rock breaking method, the purpose is to crush the rock; rock drilling rock is a special form; different ways The rock drilling method is suitable for different types of rock crushing; and so on. Therefore, a general understanding of the working object of rock drilling machinery - rock characteristics, the physical and mechanical properties and rock related rock classification, for our research and selection of rock drill and so may be beneficial, so the following briefly introduces.
