Description
Technical field
The utility model relates to down-hole gangue pump packing system, is particularly useful for the backfill of mining face under mine goaf, colliery and railways and water-bodies.
Background technology
Mineral resources are treasures of human society, be the human society indispensable material base of depending on for existence and development, but the excessive exploitation of mineral resources can cause the original ecological environment in mine to change inevitably: as vegetation deterioration, barren rock Cheng Shan, underground water descend, take good farmland, river course change move, surface subsidence, water pollution, effluent discharge and a large amount of mine tailing stackings etc.And a large amount of spoils that coal production is discharged are piled into hillock, have taken a large amount of farmlands and greenery patches, form the face of land and pollute.Therefore, make the mine solid waste discharging and goaf have not been key subjects anxious to be researched and solved by filling effectively earthward as far as possible.
Closely during the last ten years, the country of some mining industry prosperities all is devoted to research and develop efficient filling technique, uses mining with stowing technology and then reaches the purpose that improves resource efficiency, protection distant view resource and conservation of nature environment to satisfy to widely popularize.
Four developing stage have all been experienced in the development of filling in mine technology both at home and abroad, but domestic development is than external hysteresis 10~20 years, at after-stage, owing to drawn foreign experience, thereby its gap is progressively dwindled.
Phase I: before the forties in 20th century, be purpose abroad,, mine waste sent into the dead zone, down-hole not understanding fully under the situation of attal character and result of use to handle discarded object.Domestic before the fifties in last century, all be to be the barren rock dry stowing technology of purpose to handle discarded object, barren rock dry stowing mining codes once became one of main mining methods of China at the initial stage fifties.But after 1956, along with the development of actual mining technology, the barren rock dry stowing is low because of its efficient, production capacity is little and labour intensity is big, does not satisfy the needs of actual mining technology development.
Second stage: 40~fifties of 20th century, some mine developments of states such as Australia and Canada have also been used the hydraulic filling technology.From then on really begin to include filling in mine in the mining plan, become an ingredient of mining system, and research has been carried out in casting resin and filling process thereof.This stage mainly is that mine tailing is charged into underground goaf by waterpower, and the transportation concentration of its casting resin is lower, need dewater in a large number at stope.Hydraulic filling technology is just adopted in domestic mine since the sixties.
Phase III: 60~seventies, begin to use and research and development mine tailing consolidated fill technology.Because non-cemented fill does not have self-reliance, is difficult to satisfy the needs of the high rate of extraction of mining technology and the low rate of dilution, thereby after hydraulic filling technology is developed and applies, just begin development and adopt the consolidated fill technology.The consolidated fill at domestic initial stage is traditional concrete filling, promptly fully by the requirement of building concrete and technology preparation with carry cemented filling material.
Quadravalence section: 80~nineties of 20th century; development along with mining industry; former filling process can not satisfy the requirement of process for stoping and further reduce the needs of mining cost or environmental protection, thereby has developed new technologies such as high concentration filling technique, paste body filling, piece stone sand plasm glue jointed filling and full mine tailing consolidated fill.After the high concentration filling is meant that casting resin arrives stope, a kind of filling method that though there is excessive moisture to ooze out, the rate of infiltration of its excessive moisture is very low, change in concentration is slower.This filling process has seriously restricted and has applied because efficient is low, cost is high, labour intensity is big.
In addition, in coal mining, spoil transported to ground from the down-hole and charges from the surface transportation to the down-hole, need to drop into a large amount of funds.Therefore, implement downhole gangue filling can not only minimizing downhole gangue transportation lifting capacity, alleviate mining assistant conveyance pressure, and can reduce ground spoil floor space, the favourable conservation of nature environment that benefits.
At present, many collieries downhole gangue filling systems of being made up of equipment such as turning over cash machine, transporter, throwing cash machine that adopt with the direct goaf after underground filling is discarded tunnel or coal face hydraulic support of gangue more.But because the spoil conveyer moves constantly outward in the waste filling process in this system requirements filling lane, frame is constantly removed, belt constantly shortens, tail unloads cash point and waste filling portion overlaps, and has influenced production efficiency, has strengthened working strength of workers; In addition, belt is carried spoil, need tunnel a tunnel again on next door, main tunnel, its cost height, and also filling area filling floor is low, dust is big.
The utility model content
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, and filling effect is good, and cost is low, does not need to increase digging laneway, promptly realizes carrying at a distance the down-hole gangue pump packing system of spoil.
Down-hole gangue pump packing system of the present utility model, comprise that to the cash machine belt conveyor is provided with a secondary rod-toothed crusher between to cash machine and belt conveyor, give the cash machine tilting below waste bin, in the secondary rod-toothed crusher, send the direction of advance of cash to be provided with tramp iron separator for the cash machine; The place ahead of belt conveyor is provided with a powerful liquid mixer, and belt conveyor is tilting between secondary rod-toothed crusher and powerful liquid mixer; Powerful liquid mixer is other to be provided with delivery pump, is connected with the carrier pipe of the thick material spoil that flows on the delivery pump.
Described secondary rod-toothed crusher comprises two groups of gear reduction transmission mechanisms of thickness and two groups of broken discaling rolls up and down.
Down-hole gangue pump packing system of the present utility model is best suited for the backfill in mining face under mine goaf, colliery.Because fine-graded spoil slurry has rheological behavior, but can constitute the mobile thick material of similar concrete pump plasticity.Adopt down-hole gangue pump packing system, directly downhole gangue is carried out sending into after in small, broken bits and add water in the mixer and stir, the fine-graded spoil of difference is made the thick material that flows, pump into waste and old tunnel by pipeline and carry out filling, next door, main tunnel does not need to increase digging laneway, can realize that the down-hole carries at a distance.Can increase intensity after charges solidify if in broken spoil, participate in certain proportion cement, can be used for the method for mining by the way of filling, carry out railways and water-bodies, improve coal recovery rate.The native system compact conformation, method is simple, and filling effect is good, and spoil need not well, directly in down-hole treatment and utilization, has reduced the pollution of ground hillock to environment, and cost is low, and is economical and practical, has practicality widely.
