Description

A kind of mine tailing classification ore drawing device
Technical field
The present invention relates to a kind of mine tailing classification ore drawing device, belong to Ore Dressing Engineering field.
Background technology
China is a mining powers, and annual ore dressing produces mine tailing about 300,000,000 tons, and except fraction is as except filling in mine or comprehensive utilization, the overwhelming majority will be piled and is stored in tailing dam.Tailings Dam refers to the place in order to store up metal and nonmetal mill tailings of build a dam the interception mouth of a valley or exclosure formation, is the necessary facility that maintenance mine normally produces.China is mining powers, and there is tailings facilities in mine that is metallurgical, coloured, the industry such as chemical industry, nuclear industry, building materials and light industry.Can Tailings Dam safe and stable operation, play vital effect to mining production, dam body is once unstable failure, and the tailings in storehouse, mud and water will be gushed out with the form of mud-rock flow, serious threat is caused to the lives and properties of downstream resident, also will cause environmental disaster.
Current, the maximum feature of China's tailing dam is: China more than 85% tailing dam adopts the upstream type mode of building a dam to build, and upstream type tailing dam has, and dam structure is complicated, particulate interlayer, the defects such as poor permeability, saturation are high, the tailing dam dam-break accident occurred in recent years mostly also is the tailing dam that upstream type is built a dam.Meanwhile, the science research input of China in tailing dam is few, lagging of scientific research, and scientific and technological level is low.Cause the serious accidents such as tailing dam dam break occur again and again, as on September 8th, 2008, there is especially big tailing dam dam-break accident in Xin Ta mining industry Co., Ltd of Xiangfen in Shanxi, and 270 people are dead, and this time accident causes extremely severe social influence and environmental hazard.Be called " the tailing dam accident that the whole world is maximum up to now " by Administration of Work Safety Supervision, according to statistics, since calendar year 2001, having there is number in ascendant trend year by year in national tailing dam accident, only within 2007, just there occurs 14 tailing dam security incidents.
In tailing heap dam process, the distribution of whole dam body mine tailing granularity plays key effect to whether stablizing of tailing dam.The different form of export of mine tailing can form different dam body situations.Such as: dispersion discharge can make deposition dam body keep evenly along the axis of dam; Discharge after cyclone classification, before coarse granule mine tailing can being concentrated on dam, improve the deposition beach gradient.The difference of concentration during tailings discharging, the dam structure formed also has a great difference.So, by tailings particles classification reasonable in design, the good and dam body of good stability of granularmetric composition can be formed.At present, upper reaches method tailing heap dam, discharges mine tailing before dam exactly, namely mine tailing flow out from the discharge mouth of pipe after in dam dynamic, the deposition in domatic upper reaches, form dam body by the mine tailing deposited.In this flow process, owing to having close relationship by the situation of mine tailing flowing and deposition and the concentration of mine tailing, mine tailing in discharging the flow velocity of the mouth of pipe, flow, the length of grade on deposition beach and the gradient etc.When pulp density when tailings discharging is high, flow velocity is high, flow is large, now mine tailing is similar to the flowing of mud-rock flow in the flowing on domatic, i.e. a kind of moving movement of entirety, now mine tailing lithosomic body can not form obvious carse, medium and small particle subregion before dam, be essentially Total tailing grain composition to deposit on deposition beach, mine tailing no longer produces classification in deposition process, and this is unfavorable for the draining of tailings dam, thus increase the height of dam seepage line, greatly increase the risk on tailing dam landslide.The present invention devises a kind of novel mine tailing classification ore drawing device, and mine tailing first can be carried out grain size grading by this device, and then discharges the mine tailing of its carse, medium and small particle separately, thus greatly increases the stability of tailing dam body.The object of this novel mine tailing classification ore drawing device is: 1. can ensure that the mine tailing of building a dam is all coarse granule mine tailings, and namely coarse granule tailings discharging is outside tailing dam body, in building sub-dam location.Build sub-dam to heap like this and create good condition, guarantee quality of building a dam.2. fine grained mine tailing is then away from sub-dam, directly enters in storehouse far away, like this, is just difficult to form fluid-tight thin interburden layer near sub-dam, very beneficial to the stability on dam, plays good effect to the reduction of saturation.3. mine tailing is without the need to carrying out full tail discharge, but carse, medium and small particulate emission, reduce ore drawing washing away dam body like this, not being destroyed of protection atom dam, this can not only increase the stability of dam body, and can play the flood retention effect on sub-dam very soon.Therefore, the present invention, by carrying out gravity separation to mine tailing, then carries out ore drawing respectively to the mine tailing of carse, medium and small particle respectively and builds a dam, thus effectively reduces the height of tailing dam body saturation, thus greatly improve the stability of tailing dam body, reduce the probability that tailing dam has an accident.
