Abstract

Embodiments of the invention disclose a blasting security analysis method and analysis system based on continuous digital vibration measurement. The method comprises steps of generating a current blasting vibration strength formula by using a method a or a method b; entering blasting process parameters, calculating an estimated blasting strength threshold corresponding to each blasting time delayinterval, establishing a time-vibration strength corresponding array, and obtaining a standard blasting vibration model; after blasting is started, continuously collecting actual vibration speed of asite D<real>, obtaining actual vibration speed at a blasting time point, comparing the actual vibration speed with an estimated vibration speed threshold of same blasting time interval, if the actualvibration speed is less than the estimated vibration speed threshold by 20%, alarming, and labeling a time point of abnormal blasting. The method can obtain accurate change parameters of a current environment without mass calculation and environment and soil quality detections, can calculate the blasting strength threshold and compare and determine whether actual blasting strength after blasting is qualified, so that the system can accurately infer whether unexploded charge exists.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of civil explosion vibration measurement, in particular to a blasting safety analysis method and analysis system based on continuous digital vibration measurement. Background technique [0002] The dosage of engineering blasting is relatively large at one time. In order to achieve good blasting effect and reduce blasting vibration, the blasting is generally carried out in stages, and the blasting is initiated with a differential delay. During the blasting process, due to some uncertain factors, blind shots may occur during the blasting process. Blind shots produced by blasting can easily lead to accidents, and the traditional blind shot identification method is mainly based on the experience of the staff. There are many loopholes in this method, and the results are often difficult to accurately reflect the actual situation. Therefore, it is of great practical significance to study ...
