摘　　要：目前煤矿岩巷主要采用硬岩掘进机及炮掘工艺进行施工,硬岩掘进机对巷道断面尺寸及岩石硬度有一定要求。炮掘工艺又相对较为落后、具有危险性高,进尺慢等缺点,工人劳动强度大。为实现在小断面岩巷机械化施工,可以利用冲击破岩机理,设计开发一种液压冲击式凿岩机,实现岩巷小断面巷道的高效施工。The coal is currently the main rock roadheader use of hard rock and artillery to carry out the construction process of digging, hard rock tunnel boring machine on the section size and hardness of the rock has a set of requirements. Gun - de - sac and the relatively backward technology, there have a high risk of footage, and other shortcomings of the slow, labor - intensive workers, in order to achieve a small section in the rock mechanical construction, suggest nism, designed to develop a hydraulic shock - rock construction and efficient that the impact of the use of rock - breaking , rock the realization of a small section of mecha- roadway
