The system comprises a multi-stage belt conveyer, a toothed roll crusher, a strong vibration grading screen, a selective crushing type coal gangue separator, a spiral grading screen, a double roll crusher, a continuous strong stirrer, a bottom groove belt conveyer and a conveying pump, wherein the toothed roll crusher and the selective crushing type coal gangue separator are used for carrying out primary crushing and selective crushing, and the strong vibration grading screen and the spiral grading screen are used for screening in two stages; the screened coal is conveyed into a coal bunker through the bottom groove conveyer; and the screened gangue is finely crushed and then conveyed into the continuous strong stirrer to be stirred with water to form thick materials, and the thick materials are conveyed to the underground goaf to be filled through the conveying pump. The system can realize acquisition operation under the complex conditions of buildings, water bodies, railways and the like, improves the recovery rate of the coal, simultaneously reduces the cost of exploitation of the gangue, aboveground separation of the coal gangue and the like, reduces the floor space of the gangue, and reduces the geological disasters such as spontaneous combustion, acid rain and the like caused by stacking the gangue on the ground.
Description
Technical field
The present invention relates to downhole gangue sorting filling system and method, it is higher and need the gangue sorting backfill in mining face under mine goaf, colliery to be particularly useful for percentage of shale content such as alternate heading.
Technical background
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.In addition, 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 not only minimizing downhole gangue transportation lifting capacity, alleviate mining assistant conveyance pressure, and can reduce ground spoil occupation of land, the conservation of nature environment, social benefit has good prospects.
It is in the down-hole bastard coal compound under adopting to be carried out selective crushing that downhole gangue separates filling technique, utilize the nonhomogeneous hardness of bastard coal, identical impact force makes the lower coarse coal of hardness be broken into fritter, and the bulk spoil keeps original lumpiness substantially, by sieve broken coal and broken spoil are separated then, promoted by transportation system and gone up well, and spoil is broken for particle and the micro mist that thickness does not wait in the down-hole by certain grating, and fully mix, but constitute the mobile thick material of a kind of pump plasticity, be pumped to the goaf through pipeline and carry out filling.Participate in certain proportion cement or flyash and can increase intensity after charges solidify if dash, to can be used for the method for mining by the way of filling, to carry out three unders in coal mining, to improve coal recovery rate at broken spoil.
Summary of the invention
The objective of the invention is to overcome the weak point in the prior art, a kind of downhole gangue pumping separation filling system and method that realizes the bastard coal detached job in the down-hole simple in structure, easy to operate, low-cost, direct is provided.
Downhole gangue sorting filling system of the present invention, comprise belt conveyor, toothed roll crusher, powerful vibrations classifying screen, select crushing type gangue separator, spiral grading sieve, oppositely rolling roller crusher, continuous strong stirring machine, kerve band conveyer, delivery pump, described belt conveyor is the multi-stage, belt conveyer, described toothed roll crusher, powerful vibrations classifying screen, select crushing type gangue separator, spiral grading sieve, oppositely rolling roller crusher, continuous strong stirring machine is located at multi-stage, belt conveyer junction respectively successively, the below of spiral grading sieve is provided with conveyer belt oppositely through selecting the kerve band conveyer of crushing type gangue separator and powerful vibrations classifying screen below, and continuous strong stirring machine connects the delivery pump that links to each other with conveying pipeline down; Described multi-stage, belt conveyer is 5 grades.
Downhole gangue sorting placement method of the present invention: the bastard coal compound that underground mining comes out is through the multi-stage, belt conveyor delivery, carry out one-level fragmentation and selective crushing by toothed roll crusher and selection crushing type gangue separator earlier, and carry out the two-stage screening by brute force vibrations classifying screen and spiral grading sieve; The coal that sieves out through the kerve conveyor delivery to coal bunker; The spoil that sieves out carries out the careful fragmentation of secondary by oppositely rolling roller crusher again; Careful level spoil behind the two-stage crushing is sent to adds entry in the continuous strong stirring machine and stir, by delivery pump the spoil thick matter pump is gone out at last, deliver to the goaf for the treatment of filling through transfer pipeline.
Beneficial effect: adopt and vertically arrange the adaptation underworkings, do not need to increase other auxiliary digging laneways, in the down-hole bastard coal compound under adopting is carried out selective crushing, utilize the nonhomogeneous hardness of bastard coal, identical impact force makes the lower coarse coal of hardness be broken into fritter, and the bulk spoil keeps original lumpiness substantially, by sieve broken coal and broken spoil is separated then, and broken coal is promoted by transportation system goes up well; And spoil is broken for particle and the micro mist that thickness does not wait in the down-hole by certain grating, and fully mixes with water, but constitutes the mobile thick material of a kind of pump plasticity, is pumped to the goaf through pipeline and carries out filling.This system can be implemented under the building, under the water body, the collection operation under the inferior complex conditions of railway, improve the rate of recovery of coal, reduce spoil simultaneously and gone out expenses such as well, the aboveground separation of bastard coal, reduced geological disasters such as spoil ground floor space and spontaneous combustion that the spoil ground stacking caused, acid rain simultaneously.Directly carry out waste filling and not only reduce downhole gangue transportation lifting capacity, alleviate mining assistant conveyance pressure, and can reduce ground spoil occupation of land in the down-hole, the conservation of nature environment, social benefit has good prospects.This system compact, method are simple to operate, are convenient to safeguard, it is good that bastard coal separates filling effect, and running cost is low, has practicality widely.
