前言在岩石上钻孔是人类最古老的操作活动之一。若要推断起源,可以追溯到石器时代。用锤子冲击钎杆破碎岩石的基本原理已应用几千年了,今天仍在应用。为了在现代钻岩桃上更好地应用这个古老的原理,已做了次量的工作。本文研究有关现代冲击式钻岩机(凿岩机)的设计和产品发展中的某些技术问题。一、钻岩机的类型现代采矿和建筑工业需要在性质极不相 Introduction Drilling holes in rocks is one of the oldest human activities. To infer the origin, dating back to the Stone Age. The basic principle of using a hammer to impact the rock broken rod has been used for thousands of years and is still in use today. In order to better apply this ancient principle to modern rock peaches, a small amount of work has been done. This article studies some of the technical issues involved in the design and product development of modern percussive rock drilling machines (rock drills). First, the type of rock drilling machine Modern mining and construction industry needs in very nature
