Abstract
The invention relates to a manufacture method of a coal gangue culture substrate. The manufacture method of the coal gangue culture substrate provided by the invention comprises the following steps that a) coal gangue is crushed into particles with the particle size being 1 to 5cm; b) vinegar residues, coal gangue humic acid and macromolecular water absorption materials are added into the crushed coal gangue for forming a mixture, and the mass percentage of the coal gangue to the vinegar residues to the coal gangue humic acid to the macromolecular water absorption materials is respectively (80-85):(10-15):5:(0.01-0.1); c) the mixture prepared in the second step is paved onto soil, wherein the thickness of the mixture layer is 5 to 20cm, and the thickness of the soil layer is 5 to 10cm; and d) saline-alkali tolerant plants are planted on the substrate obtained in the third step for 2 to 3 years for finally obtaining the coal gangue culture substrate. When the method provided by the invention is used for preparing the coal gangue culture substrate, the cost for converting the coal gangue into soil capable of being used for planting crops is reduced, and the ecological environment is improved.
Description
Technical field
The present invention relates to a kind of method that rock gangue discarded in coal mining and process is used, particularly relate to a kind of preparation method of coal gangue.
background technology
Gangue is the solid waste discharged in coal mining process and coal washing process, is a kind of black gray expandable rock lower, harder than coal with a kind of phosphorus content of coal seam association in coalification course.Comprise choose from the spoil of extraction top board, base plate and interlayer and coal washing process in the digging gangue in tunnelling process, mining process wash spoil.Its main component is Al

3with micro-rare element (gallium, vanadium, titanium, cobalt).
From coal mining, China produces 100,000,000 tons of coals every year, discharge spoil about 1,400 ten thousand tons; From coal preparation, every washing 100,000,000 tons of coking coal discharge spoil amounts 2,000 ten thousand tons, often wash 100,000,000 tons of thermal coals, discharge spoil amount 15,000,000 tons.2005, domestic all kinds of coal production coal 1,045 hundred million tons, coal washing 38,500,000,000 tons, discharge spoil amount 19-20 hundred million tons.Thus, national state-owned coal mines existing hillock more than 1500 seat, accumulating amount more than 3,000,000,000 tons (accounting for more than 40% of Chinese industrial solid waste total emission volumn).A large amount of stackings of gangue, not only cover soil, influence ecological environment, spoil leaching water will pollute surrounding soil and underground water, and containing certain combustible in gangue, under appropriate conditions spontaneous combustion occurs, the pernicious gas pollutant atmospheres such as discharge sulphur dioxide, nitrogen oxide, oxycarbide and flue dust, affect the healthy of Residents in Mining Area.
Along with continuing to increase of national environmental protection law enforcement dynamics, people, to the raising of environmental quality requirement, solve coal gangue pollution environmental problem and seem more and more outstanding.And containing trace elements such as a large amount of organic, B, Zn, Cu, Mo, Mn needed for plant growth in gangue, be desirable soil matrix, how be used, turning waste into wealth is the heat subject of current research.
Carry out at present both at home and abroad about using gangue Reclamation by filling and improving the research of ecotope of coal gangue hill.
" flyash and the basic research of gangue Reclamation by filling " (" modern agriculture science and technology " the 20th phase in 2009, Li Xue, China Mining University's environment and Institute of Surveying and Mapping) discloses a kind of method using gangue Reclamation by filling.P in soil H after using the method to reclaim is very high, and heavy metal pollution is comparatively serious, is not suitable for most of plant growth.
Patent 201110001682.4 discloses a kind of preparation method of afforestation matrices for sandstone rock slopes.The method improve the physicochemical property of soil, promote revegetation, but use the method to improve soil to need to use the materials such as the glue peptone bacillus of exact magnitude, Chlamyclomoras sajao, chlorella, bacillus megaterium, stalk, feces of livestock and poultry, cake fertilizer, polyacrylamide, cement, nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, zinc fertilizer, iron fertilizer, boron fertilizer, manganese fertilizer, molydbenum fertilizer and copper is fertile, complicated process of preparation, cost is high.
Patent 200710063475.5 discloses a kind of greening method of self-ignition coal gangue hill.The method realizes the soil matrix needed for greening mainly through the soil horizon covering inert material and nearly half meter of thickness on coal gangue hill, gangue is not really utilized to contain a large amount of organic and micro-feature, also gangue is not improved, and be only a kind of trailing of coal gangue hill.
Vinegar industry, except Coal Industry National is leading, is made also very flourishing in Shanxi, and the waste residue vinegar grain making vinegar is difficult to be utilized very well always, and there is not been reported to use vinegar grain to carry out soil melioration.
Summary of the invention
For solving problems of the prior art, making full use of gangue and containing a large amount of organic and micro-feature, carrying out soil melioration by vinegar grain, turn waste into wealth, the invention provides a kind of preparation method of coal gangue.
The preparation method of coal gangue provided by the invention comprises the following steps: a) pulverize coal gangue as particle diameter is the particle of 1-5cm; B) add vinegar grain, gangue humic acid and macromolecule water absorbent material in gangue after being pulverized and form mixture, wherein the mass fraction of gangue, vinegar grain and gangue humic acid is respectively 80-85: 10-15: 5: 0.01-0.1; C) by step b) obtained mixture is layered on soil, and wherein the thickness of mixture layer is 5-20cm, and edaphic thickness is 5-10cm; In step c) matrix that obtains plants saline alkali tolerant plant 2-3 finally obtain coal gangue.
Described soil can select the cinnamon soil in the north, and in this cinnamon soil, the weight percentage of humus is 30%-50%.
Described humus with the fallen leaves of boreal forest for main component decompose form.
Described saline alkali tolerant plant can select clover, is sowed in described soil horizon by grass-seed during plantation.
Described saline alkali tolerant plant can select periploca spium, caragana microphylla or sea-buckthorn, during plantation by the growth bush transplanting of 2 years in matrix.
Described saline alkali tolerant plant can select shrubby flase indigo, Chinese pine or arbor-vitae, is transplanted in matrix by the growth higher plant of 2 years during plantation.
In the mixture of described gangue, vinegar grain, gangue humic acid and macromolecule water absorbent material composition, the mass fraction of each material is preferably respectively 83: 12: 5: 0.05.
