Abstract

The paper deals with the application of air and hydraulic hammer tools for the destruction of hard rock in the mode of continuous operation. The regularities of the effectiveness of demolition of rock, depending on the shape and angle of the executive body to the surface are deter-mined. There are recommendations for use the executive bodies of shock mining machines in the article.
