Abstract
The method that the present invention relates to be used for the coating stemming of plugged perforation in the blasting engineering and improve blasting efficiency.The present invention adopts the fast hard material of rapid hardening to pack into and coats in the bag, and mechanization is produced series of products and used for explosion, and its intensity height can reach the 80-200 kilograms per centimeter 4-10 minute stemming intensity
2The plugged perforation packing is good, can make full use of explosive energy, simultaneously work out the explosion chart automatically and combine, make blast hole utilization factor reach 95-100%, if be example to tunnel 13 square metres tunnel with the HXTBT-IBM program, each myriametre tunnel compared with prior art, can save ten thousand yuan of engineering cost 50-60, if promote the use of in the whole nation, economic benefit is very considerable.
Description
The invention belongs to the blasting engineering field, be specially adapted to tunnel and tunnelling.
Prior art in this technical field generally adopts yellow mud or water stemming material as the plugged perforation material, and this material belongs to inert material, and its obstruction intensity is low or filling speed is slow, influences construction speed and efficient.In addition, the parameter that influences explosion is more, determine that for these years blasting parameter is mainly by experience, be the formula that has some to calculate blasting parameter, but all more scattered complexity is difficult to promote the use of, the blast hole utilization factor of blasting engineering is generally all about 85% at present, thereby waste explosive and detonator have increased construction costs, can not realize building the mine with getting twice the result with half the effort.
The objective of the invention is to improve the mud material and the structure of plugged perforation, and utilize program to work out the explosion chart automatically, to realize comprehensive guiding construction.
Technical scheme of the present invention is achieved like this: loose, have water-swellable material scleroma or rapid solidification and pack into and coat the coating stemming of making cylindrical or multi-edge column-shaped in the bag, utilize this coating stemming and in conjunction with the HXTBT-IBM computer program to the roadway blasting parameter automatically the explosion chart of establishment carry out explosion, it coats, and mud material comprises that yellow mud, resin, cement, sand, gypsum, calcium oxide, three second ammoniums, cyanogen coagulate, aluminium powder, T31 coagulating agent, accelerator; When make coating stemming, available homogenous material make mix with two kinds of materials at least or more than three kinds material be composited; Its mud material by weight, filler is 20-50%, cementing material is 25-50%, additive is 25-30%; The clad material that is used for the mud material external packing is plastic products, polyvinyl alcohol paper, bafta, a kind of sealing bag that all can be made in the chemical ﹠ blended fabric.Its method that improves blasting efficiency is to combine with the explosion chart of the automatic establishment that comprises a computer program with coating the stemming plugged perforation, lack one and all can not reach higher blasting efficiency, computer program is according to by the section size of explosion, section configuration, formation hardness, explosive kind, borehole depth waits and calculates each parameter of explosion, automatically work out the explosion chart according to the blasting parameter that calculates, the reliever proximate coefficients in its explosion chart is 1.15-2.65.
Blast hole utilization factor is generally about 85% in the prior art, explosive consumption is at 2.0-4.5 kilogram/cubic meter, detonator consumes at 5.0-7.3/cubic meter, and the main cause that causes explosive, detonator consumption to surpass national standard is that the of poor quality and explosion Graphic Design of the obstruction of borehole is not optimized.Show according to test, the explosion chart that adopts coating stemming of the present invention and work out automatically with the HXTBT-IBM program, blast hole utilization factor is all at 95-100% or about to 110%, its explosive consumption reduces about 30%, and 10-15% is saved in detonator consumption, is example with regard to one 13 square meters of horizontal tunnel, 100 meters long tunnels of every driving, can many drilling depths 10-15 rice, save about 1 ton in explosive, more than 1400 in detonator.If deduction stemming cost, per 100 meters tunnel saving investments are more than 5000 yuan, as if a mineral bureau annual advance ten thousand metres tunnel, ten thousand yuan of year saving investment 50-60 will be very considerable if popularize its economic benefit of use in an all-round way in national mining industry.
For realizing task of the present invention, existing the invention will be further described in conjunction with the embodiments:
Have water-swellable material scleroma or rapid solidification and fully mix or compound branch bag the sealing of φ 10-45mm that polyvinyl alcohol paper or other clad materials make and long 100-1000mm of packing into through mechanical agitation loose in the embodiment ratio, during on-the-spot the use, to coat stemming immerses in the clear water, fill in the borehole with wooden stick coating stemming again after waiting to coat stemming and being soaked into, coat stemming through hydration reaction and setting expansion this moment, the stemming intensity that stemming and borehole wall form one generation 80-200 kg/cm blocks borehole, gases at high pressure behind the explosive charge are difficult for leaking from the heel of a shot, the explosive charge energy can be fully used, thereby has improved the utilization rate of borehole.According to task of the present invention, its specific embodiment is as follows:
Embodiment 1: formation hardness Protodyakonov coefficient f=5-10(sandstone)
Special cement 80-90%
Sand 5-13%
Aluminium powder 5-7%

T31 coagulating agent 20-40%
Embodiment 3: formation hardness Protodyakonov coefficient f=6-7(limestone)
Cyanogen coagulates 65-80%
Three second ammonium 20-35%
Embodiment 4: formation hardness Protodyakonov coefficient f=4-6(argillaceous sandstone)
Ordinary cement 50-70%
Calcium oxide 5-10%
Gypsum 20-35%
Aluminium powder 1-2%
Accelerator 2-3%
