Description

A kind of is the method for the artificial volcanized rock building block of raw material production with the coal gangue
Technical field
The invention belongs to the waste utilization technical field, relate to the coal gangue recovery and reuse of waste, being specifically related to a kind of is the method for the artificial volcanized rock building block of raw material production with the coal gangue.
Background technology
1, coal gangue is as the solid, liquid, gas three disasters various " industrial waste ", and resource has not only been wasted in its long-term stacking, accounts for and has pressed a large amount of soils, and polluted water source, soil and ambient air.Ecotope and resident's security of the lives and property in mining area have been had a strong impact on.
2, coal gangue comes out then to pile near well head with exploitation or washing more, grows this for a long time, has just formed waste dump, and these waste dumps are close to the Residential areas mostly, account for to have pressed a large amount of life lands used and building site, and a large amount of forest lands and arable land.According to the statistics made by the departments concerned; The total burden of coal gangue that present China adds up to stack over the years is about 4,500,000,000 tons; 300,000,000 tons of year outputs, nearly 1600 of larger waste dumps, about 1.5 ten thousand mu of land occupation: and accumulating amount also increases with the speed of hundred million tons of annual 1.5-2.0.This has not only destroyed the ecotope in mining area; And the natural landscape that has influenced the mining area has caused a series of societies and from heat problem.
3, coal gangue is stacked polluted source:
Contain the long-term rain of harmful elements process such as Ni, Cu, Zn, Pb, S, F, Cl in the coal gangue, avenge dripping dissolving; Change part harmful element in the coal gangue in rivers, lake and the underground water over to face of land runoff; Cause harmful element content increase in the water, also produced mineral such as virgin sulfur, realgar, ammonium chloride, thiamines stone, thenardite, alunogen, hexahydrite in the coal gangue natural region, these mineral substance receive the rainwater leaching; Can make mining area water quality sclerosis, polluted source.
4, coal gangue is stacked contaminated soil:
Remove in the coal gangue and contain SO 2, A1 20 3, outside the major elements such as Pe, Mn, also have a small amount of toxic heavy metal such as Pb, Ga, Ti, Sn, V, Co etc., coal gangue turns usefulness into through wind, Exposure to Sunlight, the five equilibrium that drenches with rain, the part element is invaded in the soil, causes soil pollution.Simultaneously, the SO in the coal gangue 2And SO 3Sulfides is met water generation chemical reaction, makes slowly acidifying of soil, destroys soil fertility, and plant can not be grown.
5, coal gangue is stacked polluted air:
The air storage coal gangue accumulates over a long period, and the mining area suspended substance is increased greatly.Coal mine waste rock is discharged obnoxious flavour and flue dust such as a large amount of CO, SO, NOX, the Air quality in severe contamination mining area naturally.
6, the coal gangue hill unstability causes the gravity disaster:
The stability of coal gangue hill is restricted by the slip resistance characteristic of bastard coal clitter basis rock soil mass, own structure, the shape of clitter and the factors such as water pressure in basic rock soil mass space.The natural repose angle of the stacking of coal gangue is the 38-40 degree, surpasses this angular range or when artificial excavation and rainfall amount intensity surpass underrange, causes the gravity disaster easily, like rubble flow, coming down, cave in etc. causes casualties and property damage.Inner at coal gangue, the space is bigger, produces a large amount of heats with the air catalytic oxidation, especially under the sultry situation of summer high temperature, is blasted in coal gangue hill inside, and serious threat is to mining area resident's security of the lives and property.
The spoil slag of coal gangue is the solid waste of discharging in the production process, and it is that present discharge capacity is bigger, and physical environment harm comparatively seriously is difficult to one of major industry waste residue that utilizes again.
Utilize in the field when coal gangue directly is used to prepare material of construction or stupalith at coal gangue, finished product become common earthenware brick or ceramic tile because of firing temperature is different, and their volume to weight ratio exists: 2000Kg ~ 3000Kg/M 3
Natural volcanized rock (being commonly called as float stone or porous basalt) is a kind of functional type environment-friendly materials, is by the porous shape stone material that is of great rarity of volcanic glass, mineral and bubble formation after the volcanic explosion.The chemical ingredients of natural volcanized rock: SiO 2: 53.82%; CaO:8.36%; MgO:2.46%; Fe 2O 3, FeO:10.1 %; Al 2O 3: 16.89 %; K 2O:2.30 %; Na 2O:2.55%.
Natural volcanized rock has that hole is many, light weight, intensity height, insulation, heat insulation, sound-absorbing, fire prevention, acid and alkali-resistance, corrosion-resistant, and advantage such as pollution-free, "dead", and it is the building and ornament materials of ideal natural green, environmental protection and energy saving.Its unit weight is at 400 ~ 1000 Kg/m 3, most volcanized rock all is a blocky-shaped particle, has only the natural volcanized rock specification of few some areas can reach 800mm * 600mm * 400mm, also will cut once more according to request for utilization in actual use.
Natural volcanized rock can be widely used in indoor and outdoor metope and ground decoration and substitute traditional lithotome and artificial ceramic tile; Also can be used for municipal square, road and roadbed masonry in a large number; The entity building wall of building construction.
Summary of the invention
