Abstract
The invention discloses a method for collecting and discharging clear liquor in a dry-type piled tailing dam, which is to construct a horizontal collecting layer on the bottom surface of the dry-typepiled tailing dam. The horizontal collecting and discharging layer comprises a sand gravel layer and a bottom collecting pipe parallel to a longitudinal axes of the dry-type piled dam; a vertical drain well is arranged along the axes direction of the bottom collecting pipe with a horizontal interval of 30-50m; the bottom of the vertical drain well is communicated with the horizontal collecting layer; the vertical drain well is heightened with the heightening of the tailing dam; the horizontal collecting and discharging layer is in hydraulic connection with the vertical drain well for combinedaction to fully collect clean liquor gathered in the dry-type piled tailing dam, and the clean liquor is finally discharged outside the dam through a communicating pipe embedded at the bottom of the primary dam. The invention has the advantages of fully collecting and discharging the clean liquor in the dry-type piled tailing dam, accelerating dehydration and concretion of tailings, greatly reducing the phreatic line of the tailing dam and remarkably improving the safety and the stability of the dry-type piled tailing dam.
Description
Technical field
The invention belongs to the mine safety technical field, relate to a kind of dry type and store up the clarified solution of tailing dam and collect the outer method of outbound side by side.
Background technology
China is a mining powers, and mine year discharging mine tailing reaches 600,000,000 tons.Mine tailing conventional exhaust technology generally adopts wet method, is the ore pulp shape and enters the storage of mine tailing storehouse.The method of new development in recent years is to adopt mine tailing press filtration dry type to store up to build a dam.Main technique is: mine tailing is starched filter-press dehydration, become the tailings cake of dry plate shape, concentration reaches about 80%, and water content only has about 20%, transports to belt conveyor or automotive then and adopts heavy rolling apparatus that tailings cake layered rolling is closely knit in the tailing dry stockyard.Dry type is stored up tailing dam and is compared with conventional wet, though reduced the water content in the mine tailing of putting in storage to greatest extent, make that the moisture content in the most of mine tailing slurry can recycling water utilization, a large amount of industrial waters have not only been saved, also save a large amount of reagent consumptions, help reclaiming institute's containing metal in the mine tailing wastewater simultaneously, environmental benefit is comparatively outstanding, but dry type is stored up tailing dam and still will be faced the collection of mine tailing clarified solution in the mining tailing wasteland and discharge problem outside the storehouse.Mine tailing clarified solution source is mainly: infiltrate rainwater to the dam body; Mine tailing rolls the infiltration of self discharging in the consolidation process of building a dam.The mine tailing clarified solution accumulates in the storehouse, if effectively do not collect and in time discharge outside the storehouse, it is fixed to have a strong impact on mine tailing, jeopardizes the security and stability of tailing dam.
The existing dry type of China is stored up tailing dam and is all lacked mine tailing clarified solution collection row facility, be the minority mines such as the Pai Shanlou of only Liaoning Province gold mine of storing up because of present successful implementation mine tailing dry type, these places, mine tailing storehouse are the northern area that annual precipitation is less, evaporation capacity is bigger (being the arid area).After the mine tailing press filtration becomes the tailings cake, because evaporation capacity is bigger, just can rolls through airing slightly and build a dam, rainwater is considerably less in addition, and is so that these dry types are stored up the mine tailing clarified solution generation of tailing dam is very little, little to the harm of the fixed formation of mine tailing.But the southern area (being non-arid area) big in annual precipitation, that evaporation capacity is little makes up dry type stores up tailing dam, the clarified solution water yield of mine tailing dam body inner accumulated is bigger, just must pay attention to the active set row problem of mine tailing clarified solution, can this is related to tailing dam safe and stable operation.
Summary of the invention
The object of the present invention is to provide a kind of clear liquor in dry-type piled tailing dam collection method, this method can effectively be collected dry type and be stored up the interior clarified solution of tailing dam, and the acceleration tailings dewatering is fixed, thereby improves the security and stability of tailing dam.
Technical scheme of the present invention is: a kind of method for collecting and discharging clear liquor in dry-type piled tailing dam, dry type is stored up the dried heap dam body that tailings cake that tailing dam comprises initial dam and upstream side is pressed into, the concrete steps of this method: a communicating pipe is set at the bottom of the dam in the early stage, communicating pipe end stretch out outside the initial dam; Do the bottom surface of heap dam body and lay level set row layer; Level set row layer is made of gravel layer and a bottom of the reservior collecting pipe that is parallel to dried heap dam body longitudinal axis; Be provided with one along bottom of the reservior collecting pipe tube axis direction, the every 30-50m of level interval and vertically lead seepage well, and the bottom that will vertically lead seepage well is connected with level set row layer; The bottom of the reservior collecting pipe is terminal to be connected with communicating pipe; By said method, make to do clarified solution in the heap dam body respectively by level set row layer with vertically lead seepage well and compiled, finally be discharged into outside the storehouse by communicating pipe.The bottom of the reservior collecting pipe is the perforate floral tube.Vertically lead seepage well and be woven into cage by reinforcing bar, fill the ovum gravel in the cage, the well center is inserted one and is vertically led the floral tube that oozes.
The invention has the advantages that: collection is oozed powerful vertically the leading seepage well device and water seepage drainage effect good level set row layer carries out combined seeping water discharging mutually of ability, can get rid of the clarified solution of doing in the heap dam body rapidly, the acceleration mine tailing is fixed, significantly improve the security and stability of tailing dam, store up tailing dam and discharge because of clarified solution and freely do not influence the stable sufferer of tailing dam thereby eliminate dry type.The present invention have cost low, save unique advantages such as the energy (the mine tailing clarified solution that is collected can Artesian Drainage outbound outside), management maintenance is easy under action of gravity, have and promote the use value preferably.
