device for tunnelling tunnel, especially the tunnel safety in underground mines

摘要

the invention relates to apparatus for tunnelling tunnel, in particular the rescue tunnel underground mines, through the drilling and cutting by hydraulic, with total eliminating operation causing temperature increase or spark during urabiania calizny.device for tunnelling tunnel has rotary pole (1) to (5), a drilling panting to which the channel (2) is given a liquid under pressure. the pivot pole (1) (c) has an embedding nieprzesuwnie bunghole adapter (6) by a specified angle obracanu0105. on the cylindrical lateral cap (6) is positioned cutting nozzle (8). the adapter (6) has a channel (9), which combines the channels (3, 4) of the pole (1).
