Method for tunneling, especially the rescue tunnel in underground mines

摘要

the subject of the invention is a hydraulic tunnelling the on the road, especially in caliu017anie underground mines rescue tunnel, in which the face of tunnel is wiercony system holes. the method is characterized by the fact that each of the across on the s (3) introduces a pole with panting side driven liquid under high pressure.through the liquid under high pressure scraping in openings (3), the longitudinal and transverse cracks. then caliznu0119 remaining between naciu0119tymi apertures in the aperture (3) is separated and removed from the hollow tunnel and gets another tunnel sections in the same way.
