The usage of contour blasting methods to achieve the intended shape of the slope

WithMarta Hetmańska

The aim of the article is to present contour blasting methods that will allow to excavate the remaining rock and obtain a targeted shape of the slope. Research on reducing the impact of blasting works on the adjacent rock formations has been conducted for many years. These methods are mainly related to hard rocks, i.e., granite, basalt and sandstone. The article analyzes and describes the possibilities of using contour blasting methods in the limestone mine, so in rocks of medium and low mechanical properties. It is very important to make trial blasting, but also to use good support software as O-Pitblast, which helps in the design of specialized blasting works.
