Background technology
The identification of both at home and abroad open-air rock blasting process cartridge bag being miss-fired mainly adopts after direct observation and the explosion of blasting process the experience of quick-fried heap form relatively to differentiate.But in multilayer, arrange and multiple row chamber blasting and other on a large scale down or in the underwater demolition more; Because blasting process can't directly be observed initiation process; Whether also can't compare to determine through quick-fried heap form after the explosion has cartridge bag to miss-fire; And the location of the cartridge bag that also can't miss-fire is appearring under the situation that cartridge bag miss-fires.Cartridge bag miss-fires to follow-up slagging tap or bursting work, stays great potential safety hazard.Because of follow-up slag tap or the blast working operation process in ignite possibly before the separate explosion cartridge bag that miss-fires and stay, cause serious casualties and equipment, property loss.At present both at home and abroad the miss-fire identification of phenomenon does not still have quantitative approach to underground or underwater demolition process cartridge bag.
Summary of the invention
The object of the invention is exactly that situation to prior art provides a kind of identification of miss-firing applicable to cartridge bag in underground and under water the explosion and the localization method of the cartridge bag that miss-fires thereof.
Technical scheme of the present invention is: the seismic wave that brings out with explosion is a foundation, by before the explosion preset and prediction, explosion in actual measurement, explosion after the identification and locate three big steps and constitute of miss-firing, and:
1, presetting and being predicted as before the explosion:
1), in the surrounding rock body of quick-fried source or the face of land monitoring point of attenuation of seismic waves is set and corresponding vibration monitoring instrument is installed;
2), do not predict its corresponding functioning delay (promptly bringing out the firing time of attenuation of seismic waves segmentation waveform) according to the layout of blasting Design borehole blasting segmentation cartridge bag and the section of corresponding detonating capsule;
3), according to blasting Design borehole blasting segmentation explosive quantity in a sound and cartridge bag center thereof to the air line distance of seismic wave monitoring point and relevant blasting Design parameter, the predicted segmentation cartridge bag detonates and brings out the amplitude of seismic wave vibration;
2, the actual measurement in the explosion is: in blasting process, and through the vibration monitoring instrument that install the monitoring point, the range-azimuth when measuring explosion between each segmentation cartridge bag and seismic wave monitoring point, the vibration time-history curves of seismic wave is brought out in the record explosion;
3, miss-firing after the explosion discerned and orientated as:
1), confirms the temporal aspect and the amplitude-frequency characteristic of actual measurement attenuation of seismic waves through the attenuation of seismic waves Monitoring Data of record;
2) temporal aspect that actual measurement is obtained and the prediction data before amplitude-frequency characteristic and the explosion compare, and whether differentiate in the explosion has cartridge bag to miss-fire;
3) according to miss-fire the prediction functioning delay of cartridge bag and the physical layout drawings of cartridge bag, the position of the cartridge bag of confirming to miss-fire.
The present invention combines on a large scale down or the safety monitoring of underwater demolition dither effect, through temporal aspect and the amplitude-frequency characteristic analysis of bringing out attenuation of seismic waves, and realization the miss-fire identification and the location of cartridge bag.The present invention can carry out the test and the data analysis of attenuation of seismic waves according to existing blasting vibration test procedure, and method is simple, the identifying quantification, and identification is reliable with positioning result.
