New System of Ice Wall Strength Increase

Abstract:

The weakening of the rock massive has been determined during boring of freezing tubes. It has been proved that the freezing column is disjoint from the massive by mud solution with strength 0,7-0,8 MPa, which fills out the drill hole Ø250mm. Were established lows of forming of the shear stress regions on the freezing pipe`s circuit. Were suggested adjunctive technological measures such as exhaust solution injection in the annular space, which reducing intensity of blasting loads on freezing pipe.
