Abstract
The invention discloses filling slurry for a filling mining method and a preparation method for the filling slurry. The filling slurry is prepared from the following materials: tailings, ultrafine powder, cement and debris, wherein the tailings are mill tailings at the concentration of about 20 percent, and are thickened into high-concentration tailings at the concentration of over 65 percent; the ultrafine powder is obtained by finely grinding phosphorous slag which is discharged as waste residue after yellow phosphorus is prepared by a hot method or phosphate ores are calcined by other methods until the fineness is equivalent to that of the cement, and the cement and the ultrafine powder are jointly taken as a cementitous material; and the debris is crushed into particles with the particle size of less than 2cm, and the tailings at the concentration of over 65 percent are conveyed to a filling slurry preparation station through a pipeline and are prepared into filling slurry at the concentration of equal to or more than 70 percent by using stirring equipment. The invention is characterized in that: the filling slurry has a remarkable social benefit; a series of problems about mining filling are solved; and more importantly, the national environmental protection requirements are met, and the secondary harm is avoided. The filling slurry is applicable to the filling mining method and is particularly applicable to middle and low grade phosphorus mines.
Description
Technical field
The present invention relates to filling method, further, relate to casting resin oar of a kind of filling method and preparation method thereof.
Background technology
" mining handbook { No. the 147805th, Chinese depository library CIP data core word (2007) in metallurgical industry press in the 7th printing April in 2010; In the 20 chapter of ISBN978-7-5024-0374-4} Volume Four compaction material of filling method and Application Areas and use or the like has been detailed; Its content does not relate to particularly phosphorus ore mountain of non-metal mine; Main is how compaction material not to be reached national environmental standard about the part of carrying out filling with mine tailing in its content, and realization environmental protection filling is narrated.
It is to serve as the material of filling slip with phosphogypsum, flyash or scud and cement that Chinese patent ZL200710077624.3 " phosphogypsum cementing and post-filling mining method and pulping process thereof " discloses pulping process; After adding water, process filling slurry through complete whipping device; Filling slurry is adopted accurate level through the input of filling borehole or pumping plant, and layering gallery outside filling pipeline inclined shaft gets into the higher slice arteries and veins of filling stope again charges into stope by the higher slice mineral building connecting taxiway of filling stope.This invention can guarantee arrival at mine full capacity and stable yields, improves ore recovery ratio, and phosphate rock resource is recycled fully, remarkable in economical benefits; Can also protect mine environment effectively; The mining of solution open-stope method forms geologic hazard, the mine produces dangerous; Bring the problem of threat for face of land industrial plants, highway and house; But shortcoming that it is maximum or weak point are directly to use to the huge industrial residue phosphogypsum of environmental hazard as main compaction material filling in underground, and its harm to underground Environmental Water system will be huge.Secondly, it adopts full consolidated fill must be directed at the increase of filling cost, and this is extremely disadvantageous on cost of winning for the exploitation of the relatively poor mid low grade phosphate rock district ore of ore quality.
A large amount of rejects-mine tailings that mid low grade phosphate rock stone produces through ore-dressing technique, the tailings concentration that ore-dressing technique is come out is about 20%, and mine tailing is sent into the mine tailing storehouse.And the accumulation of mine tailing and management belong to China's Management of Major Risk scope.
Summary of the invention
The objective of the invention is in order to overcome the defective of prior art, an a kind of casting resin oar and preparation method thereof of filling method is provided.In order to realize this purpose, the casting resin oar of a kind of filling method of the present invention,
It is by being to be processed by following material:
Mine tailing, super-fine powder, cement and debris;
Each material prescription by weight: cement: super-fine powder=0.8～0.3:0.2～0.7; Aggregate-to-cement ratio is 4～12;
Debris is the particle less than 2cm, and debris is unfixing with the ratio of mine tailing; Casting resin oar concentration is equal to or greater than 70%.
The casting resin oar preparation method of filling method of the present invention, it is to be processed by following material:
Mine tailing, super-fine powder, cement and debris;
Said mine tailing is that the concentration that ore-dressing technique is come out is about 20% milltailings, and concentration is about 20% mine tailing through press filtration or bore dense mode deeply and be the high density mine tailing of concentration more than 65% with the mine tailing of 20% concentration is dense, and isolating water is back to beneficiation flowsheet;
Said super-fine powder is that the production process of hot legal system yellow phosphorus or other phosphorus chemical product is being with cement fineness suitable powdery solid as the phosphorus slag that waste residue effluxes through fine grinding through Rock Phosphate (72Min BPL) being calcined the back; It has certain cementation, can be used as the surrogate of certain consumption of cement, but can not be alternative fully, and it is compared with cement has very big cost advantage; Cement and super-fine powder are jointly as consolidating material;
Said debris is that the debris that mining produces mainly is the scud waste residue that the construction mine tunnel engineering effluxes; Milltailings can not satisfy the demands, and replenishes with debris, and debris is broken into the granulated aggregate less than 2cm; The add-on of debris is unfixing, depends on the needs;
The high density mine tailing of above-mentioned concentration more than 65% through pipe-line transportation to the filling of mine cave mouth preparation station, at casting resin oar preparation station through whipping device by prescription in weight part: cement: super-fine powder=0.8～0.3:0.2～0.7; Aggregate-to-cement ratio is 4～12; Debris is the particle less than 2cm, and debris is unfixing with the ratio of mine tailing; Mine tailing, cement, super-fine powder and debris are prepared into concentration are equal to or greater than 70% casting resin oar.
Mine tailing and debris can be realized overall material balance basically.Like this, eliminate this major hazard source of mine tailing storehouse fully, realized the exploration without waster in mine.
" aggregate-to-cement ratio " in present patent application is: the ratio of (mine tailing+debris aggregate) and (cement+super-fine powder).Standard is a weight ratio, also can be scaled volume ratio.
Cement and super-fine powder have cementation help again exceeding standard in the tailings water harmless treatment of element; The harmful element that in mine tailing, exceeds standard is cemented in and does not exosmose influence in the obturator and destroy underground ground surface environment; For further improving the harmless treatment effect, also can in the high density mine tailing of concentration more than 65%, add lime powder; Also can use part flyash to make gelling material for further reducing cost.
Debris adds after being broken into the granulated aggregate less than 2cm: the one, and the intensity after the increase obturator is fixed; The 2nd, reduce the effluxing expropriation of land and the safety and environmental protection problem of stacking and bringing of debris.
The maximum characteristics of the present invention are its obvious social benefit, have not only solved a series of problems of mining filling,
Mainly be to reach national requirements for environmental protection, do not produce secondary harm.The present invention is applicable to filling method mining, low-grade phosphorus ore mountain in being particularly useful for.
