Sergeev V.V., Maximov R.N., Vyskrebenets A.S., Gegelashvili M.V., Gurieva E.V.

The research results of the drilling instrument interaction of the previously broken mountain massif during the holes drilling are presented .It was stated that the rotation speed and axis tension increase lead to the hole cutting speed increase and the hole depth increase falls .The hole drilling using the polyethylene pipes coverage in the broken massif increases the cutting speed 1,2 – 1,35 times.
