Abstract
The paper considers the problem of hard rock blasting in confined space of railway reconstruction with widening of side-hill cuts or shelves. To ensure reliable blasting without fly rock to construct the secondary railway tracks, it is proposed to use a combination of borehole cushioned charge construction in overdrilling, large delays in explosive initiation, as well as installation of permeable convertible shelters from elastic elements.
