Description
Technical field
The present invention relates to various mine worked-out sections are carried out a kind of material and the making method that consolidated fill is used particularly a kind of foam tailings cemented filling material and making method.
Background technology
China is Mineral resources big countries, also is Mineral resources production and consumption big country.Mining is the basis of exploitation of mineral resources and utilization, but mining is providing the raw-material while for the mankind, also inevitably can disturbance and destruction ground surface environment.Along with the develop rapidly of industrial society, the mineral products demand increases sharply, and environmental disruption and trash discharge that resources development and utilization causes have become quite severe problem.All kinds of barghs of China produce about 5,000,000,000 tons in ore per year at present, and mine accumulative total is accumulated 8,000,000,000 tons of mine tailings, and wherein metal mine is stored up 5,000,000,000 tons of mine tailings, and all kinds of mine tailings of average annual growth account for more than 85% of national using industrial solid waste quantity discharged more than 300,000,000 tons.Particularly the most of mines of China industrial scale is little, and Technology falls behind, and production blindness, passivity are big, cause the mine environment severe exacerbation, have brought very big negative impact for natural ecological environment and social and economic activities.
Filling in mine, especially mine cemented filling are effective back production Mineral resources, the important leverage that realizes the mining industry Sustainable development.Mine cemented filling not only can make the mine obtain better economic benefit when reclaiming high-quality Mineral resources, and can improve resource efficiency, effectively reclaim the difficulty mining bed resource, reduce environment damage and conservation of nature environment.
Compaction material and making method are one of core technologies of mine cemented filling.Existing compaction material mostly is classified tailings or face of land rod milling sand, and the mine tailing utilization ratio is low, and a large amount of mine tailings needs face of land discharging, has not only taken a large amount of soils, and has brought problems such as environmental pollution, geologic hazard.
Summary of the invention
The objective of the invention is to cause the defective that the mine tailing utilization ratio is low, face of land area occupied causes environmental pollution, geologic hazard greatly in order to overcome existing compaction material, inventing a kind of is the foam tailings cemented filling material and the making method of main aggregate with full tailings.
The objective of the invention is to reach by following measure:
Described foam tailings cemented filling material is made up of cement, tailings, flyash, water reducer and whipping agent, and the weight percent of each integral part is:
Cement: 15.0～50.0%;
Tailings: 40.0～85.0%;
Flyash: 0～30.0%;
Water reducer: 0～1.0%;
Whipping agent: 0～0.3%.
Described tailings is various mineral dressing wastes.
Described tailings comprises classified tailings and full tailings.
Described cement means that label is silicate or the slag cement of 325# or 425#, or with other cement of label; Tailings comprises classified tailings and full tailings; Flyash comprises classification and fraction coal ash not; Water reducer means various water reducers general on the market; Whipping agent is geotechnological special-purpose foaming agent.
The making method of described foam tailings cemented filling material is as follows:
At normal temperatures, cement, tailings, flyash, water reducer are pressed described mixed, add entry and stir into pulpous state, its water cement ratio is less than 1.5, again with the whipping agent of described ratio, be prepared into foam and join stirring once more in the compound that stirs, make foam uniform distribution in compound of adding, promptly constitute foam tailings cemented filling material.
The pore size of described bubble is at 30～300 μ m, and porous nickel distributes, and the unit weight of bubble is at 0.2～0.8kN/m
3, account for 0～50% of finished-product volume.
Positively effect of the present invention is as follows: the compaction material that the present invention adopts, aggregate wherein is full tailings, adopt the main force material of full tailings, increased the tailings utilization ratio greatly, effectively reduced the accumulation of face of land tailings as the consolidated fill in underground cavity, particularly worked-out section; Adopt densification that whipping agent produces and tiny bubble group's lubrication, improve the flowability of filling slurry, reduce the consumption of water, overflow water significantly reduces, material is not emanated, and realizes down-hole pipeline gravity flow conveying, and the dewatering process of the effective volume of obturator widespread use at present improves more than 25%, reduced the drainage underground expense, the operating environment that improved well.
