Description
Technical field
The invention belongs to the engineering explosion field, specifically the method for the blind big gun processing of a kind of chamber.
Background technology
Since the 1950's, China has been widely used in Chamber Blasting the fields such as mine, traffic, water conservancy and hydropower, farmland capital construction and architectural engineering, and successful implementation the repeatedly explosion of ton.Chamber blasting is a large amount of explosives to be packed into carry out explosion in the special chamber of digging or the tunnel.Chamber blasting side's amount is large, speed of application is fast, especially worker's point of concentrating at quantity of earth work, fill out that the capital construction of deep-cutting roadbed, surface mining is peeled off and large-scale quarry engineering etc. such as the height of airport, railway, highway, from lead cave, coyote hole excavates charge explosion, can finish the work in a short time, to accelerating engineering construction speed significant role be arranged.
In chamber blasting, blind big gun on a large scale often can appear, cause shade to Chamber Blasting.How processing the blind big gun of large-tonnage chamber is stern challenges to engineering explosion personnel.Because quick-fried heap after the explosion covers, former blasting network all destroys, and can not reconnect to detonate, namely enable line and detonate, because burden destroys, again detonate also very dangerous, existing method is to adopt the quick-fried method of mending, use again excavating shaft coyote hole of vertical shaft method near blind big gun in the scope of former earth's surface, the powder charge connection is detonated again, and this method need to be excavated a plurality of vertical shafts and coyote hole, its cost is high, long in time limit, and in a plurality of vertical shafts of excavation and coyote hole, run into former blind big gun, and cause that morning is quick-fried, also can be fool proof.
Summary of the invention
The invention provides a kind of is the method for processing the blind big gun of large-tonnage chamber, only needs 1 vertical shaft of excavation and former chamber to stop up section and is communicated with, and that finds out excavation leads cave and coyote hole, and powder charge connects and detonates again, and both economy is quick, and is safe and reliable again.
The method that the blind big gun of described a kind of chamber is processed comprises Pulley lift, it is characterized in that operating according to following steps successively:
(1) the position surrounding ground situation that is embedded with explosive after the chamber engineering explosion finishes, is observed in the position of the blind big gun of judgement, and ground is protuberance not, and does not have dregs on every side, and illustrating has blind big gun herein;
(2) determine the shaft excavation position, find out overhead nearest blind big gun according to the blind big gun of determining in the coordinate of former explosive burial place and the step (1) and prop up cave, the coordinate of burying underground according to each explosive on this cave is found out two overhead nearest adjacent blind big guns, determines that the obstruction section between this adjacent blind big gun is the excavation position of vertical shaft;
(3) dig vertical shaft, adopt nine shear excavation methods, the shaft excavation position of determining in step (2) marks the vertical shaft well head, and equidistantly along the well head edge dig nine eyelets, excavate straight down along eyelet, and establish Pulley lift at well head, by Pulley lift the dregs that digs out is transported, vertical shaft digs to the cave top that blind big gun is arranged, and the diameter of its vertical shaft is 1-1.5m;
(4) cleaning tamper and the blind big gun blasting charge, by the vertical shaft that step (3) is dug the tamper under the vertical shaft the cave is removed, and enter cave of blind big gun, observe this cave structure on every side, confirm its Stability Analysis of Structures, remove the tamper that props up in the cave along a cave, find intrinsic coyote hole in this cave, and enter main cave by this cave, find out the former design coyote hole that all blind big guns prop up cave, along a hole, tamper is removed in main hole, confirms the particular location of the blind roasting and boiling as two means of processing crude drugs bag in each hole, remove the detonating material of former cartridge bag, and the inspection explosive, the explosive of the caking that makes moist is the inefficacy explosive, and its removing is taken to ground;
(5) blasting charge again, planar dimension according to front separate explosion and excavation, remeasure its vertical and horizontal section, on the cross section, measure in proportion the cartridge bag center to the minimum perpendicular distance of facing the sky scope of freedom, for arranging the minimum burden of cartridge bag, the dose of the single coyote hole of accurate Calculation, adopt super dynamite again to process detonating material, and pack into new explosive and former explosive cored, reconnect networking and obstruction, again detonate, two-way line or multiple route are adopted in the networking that again connects.
Heavy fresh processed detonating material in the step (5) is led quick-fried detonator by two 15 sections plastics and is composed in parallel, establish a plurality of detonating materials in each coyote hole, each detonating material of each coyote hole is connected with the Nonel detonator that excites that is arranged on a cave mouth respectively on same cave, the Nonel detonator of each cave mouth is drawn respectively outside the cave and is connected with being arranged on the outer propagation of explosion Nonel detonator corresponding with it of main cave, is arranged on to be connected with the detonator excitation apparatus after each outer propagation of explosion Nonel detonator of main cave is connected.
The Nonel detonator that excites of each cave mouth is formed in parallel again by two one section Nonel detonators of two groups of parallel connections, being arranged on the outer propagation of explosion Nonel detonator of main cave is to be composed in parallel by two five sections Nonel detonators, each detonating material of each coyote hole is connected with four one section Nonel detonators of parallel connection respectively on same cave, four one section Nonel detonators are connected with outer two five sections Nonel detonators of parallel connection corresponding with it of main cave respectively, are connected with the detonator excitation apparatus after every group of two five sections Nonel detonators in parallel are connected respectively.
The time-delay of described 15 sections Nonel detonators is 880 milliseconds, and the time-delay of five sections Nonel detonators is 110 milliseconds.
The present invention digs a vertical shaft and enters blind big gun and prop up cave by prop up obstruction section between the two adjacent blind big guns on the cave from overhead nearest blind big gun, and prop up cave by this blind big gun and enter main cave and other blind big gun and prop up cave, find out the coyote hole of all blind big guns, former explosive is cleaned out, again the powder charge connection is detonated, its method is simple, and workload is little, not only economical, fast, but also fool proof; And the networking that reconnects detonating material is simple, safety, again occurs miso-fire when avoiding secondary initiation.
