【 摘 要 】

The authors propose and comprehensively substantiate a mining system by cut and fill for Internatsionalnaya pipe. It is found that application of cut and fill at deep level is limited due to low strength of kimberlite and enclosing rock contact and low safety of mining owing to insufficient area of the pipe beneath the level of -950 m.
