I already did a post on the drilling rig SBSH-250 MNA-32. Now I want to show you how well the video looks and what depth and cool sounds.
Characteristics of a well for explosives ....
Diameter of the borehole 250mm
Depth of drilling 47m
That's such a cool and interesting video)))) Why did I shoot a video at night to hear the sounds.
Thank you for watching. Who likes writing comments. I still have a lot of this video with it.
My video is at DLive
