Abstract
The invention discloses a high-deep chute shaft blockage blasting cartridge and a fixed-point cartridge delivery method. A construction roadway excavated in a ventilation roadway of a chute is 2-3m higher than a work face and is communicated with a chute shaft through a duct; the duct is 90-100mm in diameter and not smaller than 3m in length. A horizontal check roadway is blocked to serve as a relief tunnel, and ores in the chute are drawn to the height of the horizontal check roadway to serve as the work face. Cylindrical cartridges are delivered to the work face along the duct. Each cartridge comprises a cylindrical main cartridge, a tapered connecting part and a cartridge thin opening; the cartridge thin opening is longer than the cylindrical main cartridge. The high-deep chute shaft blockage blasting cartridge and the fixed-point cartridge delivery method have the advantages that the construction roadway is newly excavated to prevent the original check roadway from construction damage, the dust is used to prevent blasting from further damaging the wall of the chute and causing unevenness of the wall, cartridges outside the closed chute space can be placed in the closed chute shaft conveniently; the cartridges can be centrally placed in the closed chute shaft just by providing the middle of the work face with a middle concave tapered surface.
Description
Technical field
The present invention relates to mine dredging explosion field, relate in particular to a kind of advanced pass obstruction explosion cartridge bag and fixed point and send bag method.
Background technology
In mining, because mine is mostly very high, ore transports frequently, and in order to improve, to transport efficiency cost-saving, can get through in some mines the pipeline of a similar well from top to bottom, directly topples over ore from top to bottom, transports vehicle and waits in down-hole, directly transports.Drop shaft can improve and transport efficiency on the one hand, on the other hand, because being directly vertically topples over, utilizes height, can play certain powder ore effect.But because driving in process of drop shaft can be left over some boss or ore volume when larger at the borehole wall, drop shaft meeting blockage phenomenon, how processing drop shaft obstruction is the technical barrier often running into, especially the obstruction that exceedes hundred meters of above advanced drop shafts is very large on the impact of whole operation, processes the bad safety that also can have a strong impact on underground labour.
Processing at present both at home and abroad method that drop shaft stops up mainly contains shake facture, drop shaft water flood, hydrogen balloon of big gun and hangs cartridge bag blasting procedure, perforated blasting method, mine rocket projectile facture etc., before determining which kind of method of use, generally have the explosion of one-time detection chocking-up degree, in detecting explosion and needing the processing method of cartridge bag explosion, all need the cartridge bag to deliver in the drop shaft of obstruction and working face is set and operate, working face too greatly easily causes security incident, the too little cartridge bag of working face can not normally be sent in drop shaft, sends into after drop shaft and is difficult for concentrating.
Summary of the invention
The object of the invention is to invent the on-the-spot processing of a kind of advanced pass obstruction explosion cartridge bag fixed point send bag method to solve the problem that explosion treatment cartridge bag scene can not process; Solve the problem of explosive being put into airtight pass; Solve the concentrated problem of explosive in airtight pass.
For reaching above-mentioned technique effect, the present invention adopts following technical scheme, and advanced pass stops up explosion cartridge bag fixed point and send bag method:
1) in drop shaft ventilation lane, dig construction lane, hole link, higher than the scope of operation 2～3 m, is passed through with drop shaft hoistway in construction lane, channel diameter 90～100mm, and length is not less than 3m.
2) stop up horizon check lane as pressure release passage, using ore ore drawing in drop shaft to horizon check lane height as the scope of operation.
3) use the cylindrical cartridge bag rolling to deliver to the scope of operation along duct.
Preferably, the described scope of operation is umbilicate taper surface.
Preferably, in described construction lane, be provided with apart from the safety pillar of drop shaft hoistway 4～5m.
Preferably, described cylindrical cartridge bag comprises cylindrical principal cartridge, taper connection portion and the thin oral area of cartridge bag, the large principal cartridge of the thin oral area length of cartridge bag.
Beneficial effect of the present invention:
The present invention has used a kind of cartridge bag of special shape that explosive is put together, and can specifically process according to site operation situation, and while preventing from making in advance, Cartridge shape can not be suitable for or the problem of cartridge bag dose deficiency; Utilization is newly opened construction lane and is prevented the breakage in installation to original inspection lane, utilizes duct to prevent that explosion from causing borehole wall out-of-flatness to the further damage of the drop shaft borehole wall, can also very easily the explosive outside airtight drop shaft space be put into airtight pass; Concentrate if need to carry out explosive in airtight pass, in the middle of working face, be set to umbilicate taper surface.
Brief description of the drawings
Fig. 1 is that advanced pass obstruction explosion cartridge bag fixed point of the present invention is sent bag figure;
Fig. 2 is charge structure schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, there is obstruction in the mine drop shaft in certain mine, and blocking position is approximately 208 meters after testing, and preparation is used blasting impact broken arch scheme, establishes explosive after working face in drop shaft, relies on pit shaft to transmit explosion wave suspended arch is destroyed.
For ensureing implementation personnel's safety, in the ventilation lane of drop shaft, dig construction lane 1, construction 1 top, lane apart from 3 meters of drop shaft hoistways as partition wall, the duct 2 that is drilled with diameter 90mm on partition wall is communicated with drop shaft hoistway, construction is stopped up horizon check lane 3 as pressure release passage, using ore ore drawing in drop shaft to horizon check lane height as the scope of operation 4, calculates and needs can on-the-spotly process cartridge bag after dose, cartridge bag is positioned in duct, delivers to working face along duct.
Further, construction lane height is higher than working face 3m, duct downward-sloping connection drop shaft hoistway length is greater than 3m, and cartridge bag uses cylindrical cartridge bag, delivers more convenient, the invention provides a kind of guidance quality better, can better reach the effect of fixed point, cartridge bag comprises the thin oral area 7 of cylindrical principal cartridge 5, taper connection portion 6 and cartridge bag, and thin oral area 7 length of cartridge bag are greater than principal cartridge 5, when use, first thin cartridge bag oral area is sent into duct, send into successively taper connection portion and cylindrical principal cartridge.
Construction lane in the present embodiment is 2～3 m higher than the height preferable range of working face, channel diameter needs according to explosion and tries one's best and reduce the principle that drop shaft hoistway is destroyed, when punching, aperture is 90～100mm, need very accurately explosive to be concentrated with cartridge bag and concentrated and the scope of operation can be processed as to umbilicate taper surface, can realize by little, miniature blasting.Further, for ensureing personal security in construction lane, in construction lane, establish to the safety pillar apart from drop shaft hoistway 4～5m.
Above-described is only preferred embodiment of the present invention.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the present invention, as the common practise of this area, can also make other equivalent modifications and improvement, also should be considered as protection scope of the present invention.
