Description
Technical field
The present invention relates to mineral processing and field of environment protection, relate in particular to a kind of iron tailing solidifying method.
Background technology
The mine tailing that China accumulates at present has more than 80 hundred million tons approximately, and also continues to increase in the quantity with more than 300,000,000 tons every year, nearly more than 8500 in various mine tailings storehouse.Data shows, because of the mine tailing storehouse disaster extent of injury that collapses, seepage causes is only second to earthquake, flood, nuclear explosion, ranks the 18th.In recent years, China's mine tailing storehouse collapse accident takes place in rapid succession, has caused great casualties and environmental pollution, highlights China mine tailing storehouse and has been in the accident period happening with increasing frequency.Therefore, mine tailing storehouse safety is the major safety problems of restriction Sustainable Development of Enterprises.
The factor that influences mine tailing storehouse safety is a lot, geology and meteorological condition, builds a dam and the extreme variation of storing up mode, mine tailing composition and any one link such as form, security maintenance and Supervision Measures all may cause the dam break of mine tailing storehouse.Along with the raising of technique of preparing, the mine tailing particle is more and more thinner, and sinking speed is more and more slower, and mine tailing slurry quantity sharply increases, and has more increased the weight of the security risk in mine tailing storehouse.Therefore, take the technological means of technical feasibility, economical rationality to carry out dam strengthening and mine tailing curing, realize that it is the most real and effective at present safety measure that mine tailing safety is stored up.
In order to solve the problem of tailings impoundment and existence, the tailings discharging new way is tried to explore in domestic and international many mines, comprises that the mine tailing dry type is stored up, discharge the mine tailing down-hole and the filling etc. of digging up mine.

So-called " dry type is stored up " is meant a kind of high concentration lotion CHARACTERISTICS OF TAILINGS SAND of mine tailing through output after the processed, but dry type is stored up in the face of land.This method can be stored up under orographic conditions such as valley, low-lying, level land, gentle slope, and capital expenditure is few, maintenance is simple, integrated cost is low.Application is at home and abroad all arranged, though the mine tailing dry type is stored up mine tailing safety is stacked, mine tailing is disposed greatly and is simplified.But mine tailing does not fundamentally solve in the environmental hazard that storing surface exists, and especially carries through wind-force at the arid area mine tailing and causes the large tracts of land air pollution problems inherent; In rainfall season, still exist because of accidents such as subsiding of causing of mine tailing liquefaction, landslides.
(2) down-hole discharging
For adopting open-stope method and the mine that untreated dead zone, waste and old tunnel and chamber are arranged, utilizing dead zone, down-hole discharging mine tailing is a kind of effective way.Because around the dead zone, down-hole is natural rock mass, have characteristics such as crack, anisotropy, around the goaf or bottom has stope of producing or the well lane engineering that is attached thereto, the mine tailing that mining is selected is that the material under a kind of full water state is fills up to the goaf, country rock bears internal water pressure, infiltration water certainly will make the stability of country rock or underground structure body change the safety that can cause the goaf to collapse and emit even involve surface buildings.Therefore, the discharging of mine tailing down-hole must be handled goaf stability problem and the liquefaction problem of mine tailing in the dead zone, down-hole well.In addition, the discharging meeting of mine tailing produces mining area underground water and pollutes.
(3) underground goaf filling
In the mining process of down-hole, along with ore extraction constantly to the face of land, in inert aggregates such as barren rock, tailings, add cement class Binder Materials, bashing.The filling technique of China has experienced from the dry stowing to the slush, the evolution from classified tailings, full tailings, high water retaining consolidated fill to the ointment pumping consolidated fill, and filling technique has been obtained rapid progress, is the better approach that solves the tailings discharging problem.But the mine tailing filling need be used Binder Materials such as cement, and the influence factor of consolidation effect is many, the cost height.
Because China's mine tailing is of a great variety, character varies, and mining, geology and meteorological condition have nothing in common with each other, and therefore above-mentioned several tailings processing methods do not have versatility, it still is the main mode that China's mine tailing is carried and disposed that ore pulp pumping and building a dam is stored up, and can not change in the long duration.Iron tailings normally uses mine tailing, clay and sandstone as dam body materials in the process of storing up, filling mine tailing in the dam as a kind of solid waste of output maximum.Mine tailing can gluedly not solidify in the process of storing up, and takes place easily to liquefy and flow, and then forms mud-stone flow disaster.Practice shows: existing tailing dam is constructed with the tailings impoundment mode and is difficult to satisfy security needs under extreme nature and meteorological condition, fundamentally eliminate the mine tailing stock the potential risk that collapses, be necessary to start with from novel mine tailing curing technology.It is irreversible fixed that it is taken place, and improves stability and store up efficient, avoids mine tailing to cause secondary pollution, is the technical measures that fundamentally solve mine tailing storehouse safety.
