The object of research is the rock development in the railways reconstruction in a limited space. The difficulty is that the work must be carried out in close proximity to existing railways. Therefore, at the time of work, train traffic is impossible on the considered area. In addition, blasting operations pose a certain danger to surrounding infrastructure safety, namely: for existing paths; signaling, centralization and blocking devices; contact network, etc. The technology of rocks explosive loosening is proposed, combining the use of horizontal blast holes and special covering made of damping elements, reducing rock mass spread. The use of proposed railway tracks reconstruction technology completely eliminates the time spent on blasted rock displacement from the existing railway track to the dump. Due to horizontal borehole charges use, the blast wave seismic effect on the surrounding objects is minimized. The use of mechanization means such as railway crane and horizontal drilling machine provides productivity increase in comparison with existing technologies.
