Description
Technical field
The present invention relates to mining machinery and Ecological Restoration Works crossing domain, and in particular to a kind of coal gangue hill ecological vegetation
Material sorting sieves feeder with roller in construction.
Background technology
Gangue is a kind of black and gray rock harder than coal with coal seam association in coalification course.Adopt every year on average in China
Up to more than 4.5 hundred million tons of caused gangue during coal, its comprehensively utilize ratio less than 30%, wherein be not integrated into utilizing and
Quantity around colliery is deposited in more than 3.2 hundred million tons as discarded object, more than the 20% of national solid waste total amount is accounted for, in coal
All kinds of uncultivated coal gangue hills that ore deposit periphery forms substantial amounts of 50~700,000 tons or so of coal gangue hill formation are about 450~640,
Along with what is accumulated for many years does not administer quantity in the past, uncultivated coal gangue hill total amount reaches ten hundreds of.Because gangue comes from ground
Descend and contain carbon, mineral matter, its accumulation body such as sulphur lack biological introduces a collection and species viable conditions, therefore cause coal gangue hill long-term
It is uncultivated exposed, after insolation weathering, the seepage that drenches with rain and generation spontaneous combustion, cause serious dust pollution, pernicious gas pollution, water source
Pollution and visual pollution.
Coal gangue hill ecological recovery in China's rolls what plantation was combined using local deep hole slip casting with top layer earthing more at present
Conventional method.This method deep hole grouting technology is that extension of the Geotechnical Engineering slurry injection technique in spontaneous combustion of coal gangue hill fire extinguishing field should
With its flow rate of grouting is small, speed is too slow, the duration is oversize, and fire-retardant problem is not solved, and the soil rolled is unfavorable for planting
Thing takes root growth, and pollution control and afforestation effect are undesirable.
Patent of invention " a kind of self-igniting coal gangue rock glacier slope fire extinguishing, firm comprehensive processing method " (ZL201310252809.9)
Using Shallow hole grouting and top layer jet groutinl and method, the supply of control gangue hole oxygen, eliminate oxidation gain of heat spontaneous combustion
Purpose, planting is carried out using the compound alien earth sparging planting technology of mud, taken into account spontaneous combustion of coal gangue hill prevention and control and given birth to vegetation
State recovers two aspects.At present according to the patented technology principle, using greening side slope spray seeder, with a set of mechanized equipment, two class mud
Slurry formula, a variety of construction technology patterns, carry out fire extinguishing jet groutinl, down-the-hole slip casting and vegetation and plant construction of sowing grass seeds by duster.It is it was found that this
Jet groutinl is the coal gangue hill ecological vegetation building technology of core, is that the fire extinguishing of effective spontaneous combus tion of waste heap is rid calamities and vegetation
The integral construction method of ecological recovery, its security constructed and flame-retarding fire-extinguishing, vegetation plantation quality etc. are all controlled than tradition
Reason pattern has a more substantial increase.But set because the lack of materials screening of construction workshop section, configuration mixing and injection mixing etc. are special
Standby, the mechanization degree of construction is low, and the labor intensity of worker is big, and operating efficiency is low, largely constrains jet groutinl
The application of technology.
The content of the invention
