The invention relates to the technical field of surrounding
rock blasting vibration reduction, and discloses a vibration reduction method and
system for surrounding
rock blasting under complex geological conditions, which are used for solving the problems of surrounding rock
instability, structure damage and the like caused by
blasting vibration in complex geological environments. The method comprises the following steps: 1)
geological investigation and risk grading: acquiring parameters by using geological
radar, drilling
sound wave test and the like, and dividing risk areas; (2) blasting parameters are optimized, and the explosive loading amount,
delay time and the like are adjusted according to different risk areas; (3) a vibration reduction scheme is formulated, and measures such as damping grooves, rubber pads and grouting reinforcement are adopted; and 4) monitoring feedback, collecting vibration data in real time and correcting the scheme. The
system is composed of a control center, a
geological survey module, a
parameter design module, a vibration reduction arrangement module and a monitoring feedback module, and vibration reduction control is achieved. Through geological accurate pre-judgment, parameter dynamic optimization and multi-dimensional vibration reduction, the
blasting vibration influence is reduced, the safety of surrounding rock and surrounding structures is guaranteed, and the method is suitable for
engineering scenes such as tunnel excavation and mining.
