Abstract: First,discusses in detail the blasting vibration and the principles and rules of surface displacement monitoring. Then，taking Nanfen open pit mine as a engineering case，and combining with the double systems of blasting vibration and displacement monitoring，the high steep slope of the mine is continuously monitored. Finally，based on the evolution process of slope，the mining decision-making is adjusted effectively，which promotes the slope stability in mining engineering，and provides the technical guarantee for the continuous mining in safety.

Key words: Blasting vibration, Displacement monitoring, Disaster synthetical control
