Misfire detection method and misfire detection system for explosives

Abstract

The embodiment of the invention discloses an misfire detection method and an misfire detection system for explosives. The misfire detection method comprises the following steps: establishing a blasting network, dividing n equal prediction intervals according to a blasting section, collecting related parameters, and respectively calculating a predicted value V<pre-n>, namely n predicted values V<pre-n>, of the maximum blasting vibration velocity in each prediction interval according to a blasting vibration velocity formula; and in the blasting process, collecting the actual blasting vibration velocity V<actual>, correlating the prediction interval according to the collection time, using the predicted value V<pre-n> to check the effectiveness of the actual blasting vibration velocity V<actual>, and if the effective actual blasting vibration velocity V<actual> does not exist in the prediction interval, judging the interval to be an abnormal interval. The misfire detection method and the misfire detection system for the explosives have the advantages of being accurate in misfire prediction, high in precision, simple in data acquisition and high in automation degree.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of blasting quality detection, and in particular to a blind shot detection method and a blind shot detection system for explosives. Background technique [0002] Blind shot (misfire, unexploded charge) The phenomenon that the detonator, explosive or other explosives cannot be detonated due to various reasons caused by the explosive charge of the charge package, which is called unexploded charge. The naked blind gun can be identified from the outside, but the deep hole blind gun cannot be manually identified, and it is extremely dangerous. Therefore, it is necessary to focus on the blind gun identification technology. [0003] When detonators and explosives explode, ground sounds (various waves propagating in underground rocks) will be produced. Although the ground sounds can be detected according to the current blasting process, there is a lot of noise in them, and the identificatio...
