Background technology
Construction material of the concrete as human maximum dosage, its theory have reached its maturity with technology.It is but a large amount of at present
Negative effect is brought to human settlement and the ecosystem while concrete is employed.The average life span of Chinese architecture is shorter only
For 35 years, far below the Europe service life of 70 years, Urban House Demolition and it is engineered also discarded substantial amounts of concrete, according to existing
There are data to calculate and draw the year two thousand twenty, China's discarded concrete amount is up to 6.28 hundred million tons, due to the discarded coagulation of current China
Soil 97% is all direct landfill and outdoor accumulation, can thus waste substantial amounts of land resource, and pollute environment.Therefore
How to handle discarded concrete both will not land occupation resource, the problem of pollution that can also be reduced to environment is urgent need to resolve.
Other China is maximum in the world coal production and country of consumption.The coal mining of long-term extensive high intensity produces
Plurality of abandoned mine and area huge goaf, extraction coal bed gas can be carried out to goaf after mined out；For useless
Barrow well can be divided into new abandoned mine and old abandoned mine, and new abandoned mine refers to stop producing, but in mine
Transporting equipment is not removed also；And old abandoned mine refers to that the transporting equipment that mine has stopped production in certain time and mine is complete
Remove, and mine is blocked, but this closure is only closure extraction well head at present, the goaf of underground is still empty
Lack, so that the ground in goaf such as easily settles, collapsed at the disaster scenarios it, therefore how the goaf of old abandoned mine is entered
Reduced after row filling and the problem of disaster scenarios it is urgent need to resolve such as settle, collapse.
Because the mistake of global carbon converges, i.e., mankind's activity it is for example fossil-fuel-fired discharge into the atmosphere with deforestation etc. two
Carbonoxide exceedes the increment of carbon dioxide and the phenomenon of ocean uptake amount in same period earth atmosphere, so may result in air
Carbon dioxide is more and more, and so as to cause the aggravation of global greenhouse effect, it is big to ultimately result in the global situation for extreme weather occur
Big increase, although some in known material have absorption, such as concrete to carbon dioxide, due to concrete
The construction of building is contributed to, therefore does not also have and seals required confined space up for safekeeping so as to which the envelope of carbon dioxide can not be carried out
