Description

A kind of structure method of seal in underground sequestration space

Technical field

It is specifically a kind of based on such as underground coal mine coal the present invention relates to a kind of structure method of seal in underground sequestration space Underground cavity that the artificial ground activity such as large area coal seam burned out area formed in goaf, Underground Coal Gasification Process generates or A series of structure in the underground sequestration space of the nature underground cavity such as cavities that the natural geological movement of person generates under earth's surface is sealed up for safekeeping Method belongs to underground engineering technical field.

Background technology

The underground space refers to belonging to earth's surface hereinafter, mainly for a noun for building aspect, its range is very wide, Such as the spaces such as underground commercial center, underground parking, subway, the tunnels Chuan Hai.The utilization of the underground space are urban developments To the product of certain phase, urbanization accelerated development makes Urban Underground Space Excavation utilizes to synchronize to accelerate development as inevitable.

The existing underground space development in China is mostly developed and utilized for underground shallow layer part, such as underground traffic The facilities such as facility, underground commerce facility, underground garage, Comprehensive Disaster Prevention for Cities facility, and with one line urban underground space of China Utilization, underground shallow layer part will utilize finish, underground space development will be gradually to Deep Development, Deep underground space The utilization of resource have become the major subjects of future city modernization construction.The exploitation of Deep underground space resource can also answer For the military engineerings and oil cellar etc. such as underground military commanding center, military materials deposit undergrounds storage engineering, it might even be possible to Especially it is to slow down greenhouse gas emission and the global gas of protection in recent years for sealing up for safekeeping such as nuke rubbish, heavy metal waste and other items Wait and propose " carbon dioxide is directly discharged into air to replace in a manner of capturing carbon and secure storage " carbon sequestration skill Art, the amount of storage of Deep underground space is big, stable quality, safeguards that the features such as being easy can provide for carbon sequestration and excellent seals field up for safekeeping Institute.

Underground cavity refers to the space that earth's surface or less is covered by rock stratum, generally refer to space it is larger, be located at earth's surface below The underground cavity pocket of deep layer.Artificial ground activity underground mining such as in coal mining accounts for the 60% of world's coal production, and underground The coal goaf that large area is often left after the completion of the exploitations such as underground coal or gangue is formed into underground sky in recovery process Hole；In addition, coal underground gasification technology can not only recycle the coal resources of mine abandonment, but also it can be also used for recovery well work It is difficult to exploit or exploit the poor girdle of economy, safety, deep fractures, " under three " press coal and high-sulfur, high ash, high methane Coal seam, although the lime-ash after underground coal gasification(UCG) burning stays in underground, the big face that can be also formed in Underground Coal Gasification Process Product coal seam burned out area underground cavity；In addition, natural geological movement also will produce a series of underground cavities under earth's surface.

Although underground cavity can be as the exploitation basis of Deep underground space, the exploitation of traditional Deep underground space Different from the exploitation of Subsurface, Deep underground space exploitation is equally first opened in earth's surface without the exploitation of image of Buddha Subsurface It digs foundation pit, construct in foundation pit again, the exploitation of traditional Deep underground space is normally based on BIM technology and deep excavation dress On the basis of standby and technology, typically first carry out excavating and after supporting using such as prefabricated reinforced concrete column foundation, prefabricated The PC such as exterior wall, precast floor slab components carry out lifting concatenation construction process, then carry out pressure grouting and cast-in-place node processing etc. subsequently Working procedure.On the one hand, the larger conveying of space hold is usually required in traditional Deep underground space exploitation work progress to set Standby, support apparatus and lifting equipment, it usually needs expend a large amount of manpower and materials, Deep underground space development cost is larger；It is another Aspect, Deep underground space virgin state of stress of Deep underground space after excavation is usually destroyed, to cause stress weight It is new to be distributed, in Deep underground space work progress under the action of the factors such as burden pressure and underground water, Deep underground space pole Such as wall caving, roof fall, gushing water, rock burst, the geological disaster of bump diversified forms easily occurs, construction environment is severe and constructs Operational security is poor；In another aspect, the existing Deep underground space built up only is by deep layer as sealing up for safekeeping when place uses The underground space is used simply as storage space, i.e., is placed into the container direct code that holds account property sealed up for safekeeping, space Utilization rate is restricted by the container that holds account property.
