A kind of mining filling system processing goaf
This utility model relates to a kind of filling system, is specifically related to a kind of mining filling system processing goaf, belongs to filling technique field, mine worked-out section.
Mine worked-out section is the underground vacant areas stayed after mining, if not carrying out filling, can cause surface collapse, bringing danger.Meanwhile, the tailings produced in mining process is piled up and is easily caused environmental pollution, and Tailings Dam there is also certain potential safety hazard.
Therefore, for solving above-mentioned technical problem, the mining filling system processing goaf of a kind of innovation of necessary offer, to overcome described defect of the prior art.
Utility model content
For solving the problems referred to above, the purpose of this utility model is in that to provide a kind of simple in construction, goaf can be filled with and can effectively solve the problem that the mining filling system processing goaf of tailings problem.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of mining filling system processing goaf, and it includes hopper, cement bin, agitator tank, funnel, filling slip extruder, drill pipe and sediment transport pipe；Wherein, described hopper, cement bin are respectively connecting to agitator tank；Described funnel it is provided with bottom described agitator tank；Described funnel, filling slip extruder, drill pipe and sediment transport pipe are sequentially connected with.
The mining filling system in process goaf of the present utility model is further arranged to: the bottom of described cement bin is provided with metering screw batcher.
The mining filling system in process goaf of the present utility model is also configured to: described sediment transport pipe adopts superhigh molecular weight polyethylene pipe.
Compared with prior art, this utility model has the advantages that
1. by goaf filling, solving the potential safety hazard that the large area goaf of exploitation accumulation over the years exists, control dead zone Ground pressure activity, it is prevented that surface subsidence；
2., by goaf filling, reclaiming and remain in the Ore top-bottom pillar in goaf, the some post between mineral building and earth's surface oxidized ore, to improve resource utilization, increase economic benefit.
3. tailing-filled by adopting, alleviate Tailings Dam storage capacity pressure and tailings discharging environmental protection pressure, reduce Safety of Tailings Dam risk；
4. by filling in mine, existing mining methods are carried out filling mining method transformation, improve resource recovery rate, reduce the exploitation rate of dilution, strengthen mining production security；
5. by filling in mine, mining filling and goaf filling combine, it is achieved the target of mine tailing " zero-emission ", save mine tailing construction and maintenance cost, promote mine comprehensive benefit；
6. reducing investment outlay, technique is simple and is prone to workman's grasp, is beneficial to and popularizes at Medium and smaller mines and implement.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the mining filling system in process goaf of the present utility model.
Detailed description of the invention
Referring to shown in Figure of description 1, this utility model is a kind of mining filling system processing goaf, and it is made up of several parts such as hopper 1, cement bin 2, agitator tank 3, funnel 4, filling slip extruder 8, drill pipe 5 and sediment transport pipes 6.
Wherein, described hopper 1, cement bin 2 are respectively connecting to agitator tank 3.The bottom of described cement bin 3 is provided with metering screw batcher 7 such that it is able to the cement amount that accurately metering adds.
Described funnel 4 it is provided with bottom described agitator tank 3.Described funnel 4, filling slip extruder 8, drill pipe 5 and sediment transport pipe 6 are sequentially connected with.Described sediment transport pipe 6 adopts superhigh molecular weight polyethylene pipe.Filling slip is carried by drill pipe 5 and sediment transport pipe 6 and is injected goaf by described filling slip extruder 8.
The operation principle of the mining filling system in process goaf of the present utility model is as follows: selects factory's tailings dump truck to be transported to Filling Station stockyard, is then loaded hopper 1 by wheel loader again.Cement transports to Filling Station by bulk cement tanker, with calming the anger in feeding cement bin 2.Tailings is reprinted inclination angle belt conveyor by hopper 1 bottom electric vibrating feeder, subsequently into agitator tank 3.Being provided with metering screw batcher 7 bottom cement bin 2, metering screw batcher 7 adopts VFC, and cement is quantitatively delivered to agitator tank 3 by cement-sand ratio.Filling slurry is added water after stirring and enters funnel 4 by agitator tank 3, puts to filling borehole again through filling slip extruder 8, drill pipe 5 and sediment transport pipe 6.
Above detailed description of the invention is only the preferred embodiment of this creation, not in order to limit this creation, and any amendment of making within all spirit in this creation and principle, equivalent replacement, improvement etc., should be included within the protection domain of this creation.
