Abstract
The invention provides a method for conveying coal and refilling ash and slag in goafs of a slapithead power plant and solves technical problems that: no ideal mode is available to solve ash and slagfloor occupation and environmental pollution problems of coal fired power plants; goafs are formed in a coal mine after the coal mining, and the phenomenon, still common today, causes serious geological and ecological damages such as surface subsidence; and passive refilling of the goafs increases cost and consumes finite resources of clay, sand stone and the like. The key points of the method include: an upper branch of a tubular belt conveyer conveys coal at a well head or a coal storage yard of a mine to a coal bin of the slapithead power plant; and meanwhile, a lower branch of the tubularbelt conveyer reversely conveys ash and slag generated from coal-fired power generation back to a grout injection station at the well head of the mine to refill the ash and slag in the underground goafs from a grout injection system of the mine. The method has the advantage of solving the problems of surface subsidence, ash and slag floor occupation, environmental and atmosphere pollution and thelike at one time.
Description
Technical field
The present invention relates to the Coal Transport between near coal-mine power plant and the mine and utilize its backhaul cinder of electric power plant loopback grouting pipeline to be filled the activities of underground goaf.
Background technology
For a long time, in the production of state, inside and outside secondary energy sources, consumption structure, coal-burning power plant's proportion is very big, and the annual coal that consumes has tens tons.The extraction of on the one hand a large amount of coals will unavoidably form huge goaf, cause the face of land or underground ecological disruption; On the other hand, the lime-ash that stays behind the coal burning in the power generation process also brings pollution to environment and air quality except that will taking a large amount of soils.
The lime-ash of coal-burning power plant takes up an area of and environmental pollution problem fails to find more satisfactory good processing mode always, the alternative limestone of a small amount of lime-ash is produced cement, instead of clay is manufactured building brick though utilize, but be subjected to the restriction of various objective condition, can't fundamentally realize the comprehensive regulation; And the goaf that mine forms behind coal mining also can be found everywhere at present, causes serious geology ecological disruptions such as surface subsidence for a long time, as passive backfill, increases cost on the one hand, and the person also will consume resources such as limited clay or sandstone in addition.This has arrived instant stage.
Summary of the invention
The object of the present invention is to provide the method for coal conveying of a kind of near coal-mine power plant and lime-ash backfilling goaf, it utilizes the backhaul of transporting coal, cinder of electric power plant loopback grouting pipeline is filled underground goaf, fundamentally solve the problem of man made geologic hazards such as lime-ash occupation of land, contaminated environment and surface subsidence.
The object of the present invention is achieved like this: the top set of pipe conveyer is transported near coal-mine power plant coal bunker with the coal of mine well head or coal yard, the function of its top set is for carrying coal, simultaneously, utilize the condition of inferior division idle running, the lime-ash that produces behind the coal fired power generation is oppositely backhauled to mine well head slip casting station, and the grouting pipeline system of process mine is backfilling into underground goaf.Utilize pipe conveyer adhesive tape under operation condition to have round tubular feature of one's own, coal and lime-ash are in transportation under the closed state all the time, avoiding the coal dust environmental pollution.
The present invention compared with prior art, its advantage is: it is disposable to have solved surface subsidence, lime-ash takes up an area of and environment and air quality are brought problems such as pollution.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Accompanying drawing is a system drawing of the present invention.
The specific embodiment
Ribbon conveyer 101 is given pipe conveyer 102 with the Coal Transport and the reprinting of mine or well head coal yard, utilize pipe conveyer adhesive tape under operation condition to have round tubular feature of one's own, coal is in transportation under the state of sealing all the time, under the prerequisite of avoiding the coal dust environmental pollution, coal is transported to power plant's coal store 3 with growing distance and stores and generating.Meanwhile, ribbon conveyer 103 and 104 is transported to ribbon conveyer 105 with the lime-ash the like waste material that stores in power plant ash storehouse 2 and the slag storehouse 1 respectively, and by the inferior division of its reprinting to pipe conveyer 102, utilize the backhaul of pipe conveyer to transport lime-ash to mine lime-ash transfer post 5, be transported to the lime-ash filling through common belt conveyor 106 again and prepare storehouse 4, lime-ash mixes with water after water seal drag conveyor 107 enters mine slip casting station 6, is filled in the underground goaf 7 by grouting pipeline again.
Claims (1)
1, the method for coal conveying of a kind of near coal-mine power plant and lime-ash backfilling goaf, it is characterized in that: the top set of pipe conveyer is transported near coal-mine power plant coal bunker with the coal of mine well head or coal yard, simultaneously, the lime-ash that inferior division produces after with coal fired power generation oppositely backhauls to mine well head slip casting station, is backfilling into underground goaf through the grouting pipeline system of mine.
