Blasting vibration zoning and grading control method suitable for high and steep slope

The invention discloses a zoning and grading control method suitable for blasting vibration of a high and steep slope, and relates to the field of rock mass safety protection in slope engineering. When the method is adopted to carry out zoning and grading on the open slope stope of the mine, the rock mass quality evaluation is carried out by fully considering the mechanical characteristics of the rock mass of each part and combining the joint fissure investigation, and meanwhile, the blasting vibration velocity prediction model is established by considering the influence of various factors such as the elevation and the gradient on the blasting vibration velocity propagation; and refined management of blasting vibration control of each part of area of open-cast mining is realized. Different blasting parameters are adopted according to geological conditions and structural characteristics of different areas through zoning and grading, so that the influence of vibration on the surrounding environment and faciliti
