Abstract

The embodiment of the present invention discloses a blasting safety analysis method and analysis system based on digital noise detection, including collecting at least two groups of blasting detection information, and establishing a relationship formula between the sound pressure of the current detection point and the blasting charge according to the blasting detection information; The relationship formula between the sound pressure of the detection point and the blasting charge is established to establish a standard blasting noise model; after the blasting is started, the actual noise at the measurement point is collected continuously, and the standard blasting noise model is used to verify the actual blasting noise at the blasting delay interval. Verify that the actual blasting noise exceeds the standard and give an alarm. The present invention can accurately obtain the changing parameters of the current environment through previous experiments without the need for a large number of calculations and detection of the environment and soil quality, so as to calculate the threshold value of blasting intensity, compare the actual intensity after blasting with the threshold value of blasting intensity, and give feedback according to the comparison result In the case of blind shots, the system accurately infers whether there is a blind shot, without manual mine clearance, high security, timely and efficient alarm.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of civil explosion detection, in particular to a method and analysis system for blasting safety analysis based on digital noise detection. 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 a practical, fast and rel...
