4) digital primer blast delays to be provided with: through step 2) time-delay of detonating between the big gun hole confirmed, according to the cloth hole pattern, preview through computer logarithmic code detonator blasting sequence, check the defer time data to be downloaded to the intelligence equipment that detonates after errorless;
5) digital primer filling: after the punching of explosion face finishes, by the staff according to the cloth hole pattern, with the detonator hand-hole of checking the number;
6) networking connects: dynamite charge finishes; Whether lack with the detonate correctness and the detonator at Equipment Inspection networking of intelligence, check errorless after, the detonator payment to a porter with parallel way access communications branch line; Simultaneously each regional branch communication line parallel connection is gathered the access communications bus, get into the flow process of detonating;
7) flow process of detonating: at first with opening the initiator charge switch, press two buttons that detonate then, charge and detonate after 5 seconds.
Application digital primer of the present invention is realized full section photoface exploision construction method; In step 2) in: try the blasting vibration waveform that quick-fried time-division division is given birth to,, find out the half cycle duration of master oscillator frequenc through gathering the blasting vibration waveform; Confirm the defer time of digital primer then according to this, realize the misphase vibration damping.
Application digital primer of the present invention is realized full section photoface exploision construction method; In step 7): at first check network once more before detonating with the intelligence equipment that detonates; In initiator, detonator is called the roll earlier; Add up detonator number in the whole blasting network; Check the detonator state, all detonators get into the ready state of detonating then.
Beneficial effect compared with prior art of the present invention is: application digital primer of the present invention realizes that the more common explosion of the blast fragmentation of full section photoface exploision construction method improves 40%; Smooth effect improves 30%; Can carry out full-face blast; And increased cyclic advance; Blasting vibration control effect is obvious; Though construction cost is higher slightly than drilling and blasting method, it is with the obvious advantage to compare other method, has remarkable social benefit and economic benefit.
