Broken requirement blocks blasthole 6, and when blocking will ensure not coupling pack and will not be destroyed in blasthole 6, meets not coupling
Attach together the design parameter and quality requirement of medicine.
Process, which can be seen that, from the process above does not couple after pack design and fabrication finishes, and the blasthole in an area Ge Bao can
With according to not coupling, cartridging process, pack adaptively adjust process and multiple-row blasting carries out continuous productive process tissue, it is ensured that apply
Work tissue without any confusion, construction quality standard it is reliable.
Embodiment 2:
During large surface mine is exploited, large-scale side slope molding control bursting work is needed, including presplitting is quick-fried
Broken and photoface exploision, to ensure the safe and stable and beautiful of open mine side slope.
Side slope molding control explosion needs the explosive payload of strict control presplitting blasthole or smooth surface blasthole, often uses and does not couple
Charge constitution, i.e., the charge diameter of powder charge section is less than blasthole diameter in blasthole, controls the linear meter(lin.m.) explosive payload in blasthole.Usual situation
Under, presplit blasting and Smooth Blasting Construction are carried out using finished product small-diameter explosive roll, explosive cartridge is arranged successively and is bound in bamboo
On the framework materials such as piece, by primacord series connection and each explosive cartridge that detonates, the processing of explosive and powder charge process labour are strong
Big, low efficiency is spent, the requirement of the large-scale side slope molding control blast working of large surface mine is often unable to satisfy；Therefore,
A kind of open mine side slope shaping blasting method is present embodiments provided, as shown in figure 4, method includes the following steps:
Step 1: being required according to the linear charging density of presplit blasting or photoface exploision, a certain diameter of selected or customized processing
Loading hose, the diameter of loading hose is calculated according to the following formula:
Q=1/4 π d2ρ0
Wherein, d is the diameter of loading hose, and q is the linear charging density of presplit blasting or photoface exploision, ρ0It is on-site mixed
The upper limit value of emulsified detonator loading density, takes 1.3g/cm3。
In this step, the determination of loading hose diameter takes according to the linear charging density of conventional presplit blasting or photoface exploision
Value bigger than normal is counter to be pushed away, and linear charging density is reduced by way of improving foaming degree makes it coincide with design lines powder charge intensity, after being
It is continuous that according to practical demolition effect progress powder charge intensity fine tuning, there are sufficient spaces.
Step 2: it is soft to intercept 0.5 meter of powder charge longer than loaded length according to the loaded length of presplit blasting or photoface exploision
Pipe.
The powder charge of the loading hose handled by step 1 and step 2, as presplit blasting or photoface exploision is soft
Pipe.
Step 3: the detonator wire of detonating capsule is packed into simultaneously from one end of loading hose with the polyvinyl chloride pipe of minor diameter
It is sent to the other end of loading hose, is connect with detonating material (such as detonation tool, igniting primer), makes one end conduct where fire point
The bottom of loading hose, top of the one end far from fire point as loading hose, is bound by binding piece (such as rope) and is filled
The bottom of medicine hose, making the bottom of loading hose, there are taps.
Step 4: loading hose is sent into inclined presplitting or smooth surface blasthole by the polyvinyl chloride pipe of minor diameter by scene
In, in blasthole, loading hose exposes 0.5m at blasthole aperture for the lashing location of loading hose.
Step 5: the explosive loader of on-site mixed emulsion is protruded into loading hose, control reasonable powder charge speed and
Propellant charge pressure inputs emulsion matrix to loading hose quantification, and for emulsion matrix to bottom squeeze at the top of loading hose, powder charge is soft
The tap discharge air of bottom of the tube is conducive to emulsion matrix and conveys and flow in loading hose, to not coupled medicine
Packet.
In this step, the emulsion matrix of input is the emulsion matrix of unexpanded sensitization, and the density of the emulsion matrix is greater than quick-fried
The degree of packing of broken conceptual design, the loaded length of the emulsion matrix are less than the loaded length of blasting scheme design, rationally really
Determine explosive loader and go deep into the length of loading hose to make lower part powder close to the bottom binding piece of loading hose.
Step 6: will not couple pack is sent to blasthole bottom, the polyvinyl chloride pipe of minor diameter is drawn back to reuse.
Step 7: not coupling pack self-control effect, emulsion matrix is sensitized and foams in blasthole, density reduction, body
Product expansion, gradually becomes the suitable emulsion of sensitivity to initiation, with the volume expansion of emulsion matrix, emulsion explosive is soft from powder charge
The bottom of pipe is extruded, and is filled between loading hose and blasthole, and blasthole base charge, while emulsion top medicine are strengthened
Face is gone up, and filling loading hose does not have all or part of emulsion matrix section.
Step 8: after blasthole internal emulsification explosive sensibilization and foamed time are met the requirements, according to conventional presplit blasting or light
The requirement of face explosion blocks blasthole, and when blocking will ensure not coupling pack and will not be destroyed in blasthole, meets not
The design parameter and quality requirement of coupling charging.
Step 9: according to explosion design blasting circuit require network, then carry out blast warning, detonation and it is quick-fried after
It checks, completes this bursting work.
Step 10: statistical analysis demolition effect, finds out and needs the blasting parameter that optimizes, as in blasthole linear charging density,
Loaded length etc. in blasthole, optimizes blasting parameter, re-starts bursting work next time, until demolition effect meets
It is required that.
In this step, blasting parameter is optimized, is specifically included:
A, the blasting parameter if desired optimized is the linear charging density in blasthole, then adjusts the hundred of foaming agent and emulsion matrix
Divide ratio, concentration of foaming agent etc., to optimize linear charging density, in the case where loading hose diameter determines, foams more, then it is newborn
The density for changing explosive is smaller, and the linear charging density in blasthole is smaller.
B, the blasting parameter if desired optimized is the loaded length in blasthole, then adjusts the input quantity of emulsion matrix, with control
Loaded length in blasthole processed.
In this step, demolition effect meets the requirements the line for referring to that the linear charging density in final blasthole designs for blasting scheme
Degree of packing, the loaded length that the loaded length in final blasthole designs for blasting scheme, at this time it is believed that demolition effect is excellent.
In conclusion the present invention is constrained by the diameter of loading hose in blasthole, presplit blasting or photoface exploision big gun are realized
The requirement of hole decoupling charge structure and linear charging density control, while passing through the foaming degree of on-site mixed emulsion, cream
The input control of gel matrix realizes the adjusting of the linear charging density in blasthole, the loaded length in blasthole, to meet subsequent apply
The demand of data of explosive filled fine tuning is carried out in work according to practical demolition effect, and improves the mechanization degree of powder charge, is reached
Simple and fast production does not couple the purpose of pack and charge explosion construction, and construction auxiliary consumptive material is few, and construction cost substantially reduces.
The above, only the invention patent preferred embodiment, but the scope of protection of the patent of the present invention is not limited to
This, anyone skilled in the art is in the range disclosed in the invention patent, according to the present invention the skill of patent
Art scheme and its design are subject to equivalent replacement or change, belong to the scope of protection of the patent of the present invention.
