Embodiment:
Certain goaf contaminated sites rehablitation project, project discard 77 meters of colliery well depth.Offender leases the colliery courtyard,
It specially collects, topple over hazardous waste.4 people are caused to be poisoned to death on the spot due to generating chemical reaction generation toxic gas in hole.Thing
After part occurs, government sets up emergency processing headquarter immediately, has carried out emergency disposal to the barreled waste of scene discovery.It is right afterwards
Accident well carries out cement lid note and seals up for safekeeping.Recovery project need to carry out clear digging processing to for accident well solid waste first, carry out mine afterwards
Main shaft pollutant rotary digging processing, follows the steps below construction:
1, construction inclined shaft.Inclined shaft is used for aspirating hole and sampling hole.Inclined shaft of constructing around main shaft is connected to accident well, hole deviation
30-45 °, inclined shaft diameterTripping in casing slip casting sealing, wellhead flange sealing, flange are connected to ball valve.
2, extract system is installed and is uncapped.Aspiration pump is installed in 1 well head of inclined shaft first, aspiration pump tail end connects active carbon
Automatic monitoring and warning equipment is arranged in tank, activated carbon tube tail end.It starts aspiration pump and extracts 1 gas of inclined shaft, keep certain time negative pressure,
2 wellhead flange of inclined shaft is opened, air enters in accident well from inclined shaft 2, replaces toxic gas in solid waste, ground is extracted out along inclined shaft 1,
It is up to standard through charcoal canister oxidation-adsorption, in high air discharge atmosphere.It keeps this process cycles after a certain period of time, is excavated on well head periphery
Exhaust tube is installed at about 2 meters of depth and keeps pumping, be evacuated body is through charcoal canister oxidation-adsorption.Then on main shaft periphery 2 meters apply
Work collar tie beam protects well head, increases well head periphery Rock And Soil intensity, forms job platform, is conducive to anti-while rotary drilling rig operation
Only well head collapses.Concrete manhole cover, Fast Installation movable manhole cover are opened, movable manhole cover seat hangs down above accident well with Spiral digging machine
Histogram is to arrangement.Well lid covers accident well completely, and vertical Spiral digging machine is laterally opened, in movable manhole cover installation process, in well head
Movable draught hood is set, the gas of loss to earth's surface is persistently extracted, the gas of extraction is connected to exhaust-gas treatment system by pipeline
Discharge after system processing is up to standard.And fence is set around workspace.
3, protection is excavated in the rotary digging of accident well.
The method that accident well solid waste uses rotary digging to extract carries out next step safe handling after extracting to ground.
Rotary drilling rig is fixed on drillng operation platform, according to actual operation, adjusts drill bit.
After each rotary drilling rig starting, first rotary digging drill bit is stopped at right above movable manhole cover, drill bit is vertical after opening well lid
It falls, closes well lid after drill bit is completely into accident well, drill bit falls to respective depth and excavated.Amount to be excavated is extremely
1m3When, it is promoted near drill bit to well head, then open well lid and the drill bit for filling solid waste is proposed into well head, is transferred to lower hopper discharging.
The rotary digging of accident well carries out operation by having the personnel of professional qualification, and to guarantee safety, operational period, single opening and closing is completed
Time is not more than 1min；Well lid should propose to open in face of ground in rotary digging head, and rotary digging head is closed when being inserted into；When daily work is completed,
Well lid is closed, and seals the circular hole of well lid, achieve the purpose that seals accident well and prevents rainwater from entering.Exhaust tube is in rotary digging process
In be always maintained at ventilating state, exhaust gas enters adsorption tanks processing, guarantees to form negative pressure in well, it is ensured that well head volatility is organic
Exhaust gas does not escape.The gas of extraction passes through pipeline to exhaust treatment system processing rear discharge up to standard.
When at night without rotary digging operation, movable manhole cover and exhausting system and the closed measure for carrying out place of leaking out are closed, if
Live peculiar smell is heavier, then needs to open exhausting system progress exhausting.
4, solid waste discharging and transhipment
Solid waste after rotary digging is packed in such a way that lower hopper blanking is packed into jumbo bag or direct blanking is packed into jumbo bag.
In the actual operation process, due to pollutant via rotary drilling rig pour into lower hopper pack can generate during this it is certain
Exhaust emission, therefore a set of side air draught gas gathering mask is arranged above lower hopper collects the useless of loss in pollutant in blanking process
Gas, and enter adsorption tanks adsorption treatment.The slow vertical-lift of dump skip in discharge process, it is ensured that accident well solid waste is not spilt.
Each jumbo bag solid waste carries out scene pH and examines, preliminary judgement acid-base property, and is identified.It is packed into the solid waste of jumbo bag,
The stacking of film greenhouse corresponding region is transported to using fork truck after sealing.
Solid slag after packing is transported through the east side loop line in place to working area in repair membrane greenhouse by fork truck,
Carry out identification label.
5, solid waste is stored up
According to the difference of solid waste pH acid-base property, its subregion is stacked in film greenhouse, dump region schematic diagram such as Fig. 3 institute
Show.Aspiration pump duration exhausting is arranged in greenhouse, forms tiny structure, high idle discharge after taken out gas well charcoal canister adsorption and oxidation is up to standard
It is put in atmosphere.It also sets up special messenger to be managed, without permission, must not arbitrarily enter.
6, monitoring and warning system
Real-time dynamic monitoring source of early warning is installed in each charcoal canister tail end.The equipment has data storage function and report
Alert system, when Pollutant emission concentration reaches early warning value, system meeting and alarm, linkage emergency.
The foregoing is merely preferred embodiment of the present disclosure, are not limited to the disclosure, for the skill of this field
For art personnel, the disclosure can have various modifications and variations.It is all within the spirit and principle of the disclosure, it is made any to repair
Change, equivalent replacement, improvement etc., should be included within the protection scope of the disclosure.
