Background technology
Because rock salt has good rheological characteristic, constantly shrink at shut-in well rear chamber volume in discarded salt chamber, easily bring out the geological disasters such as land subsidence, the large tracts of land pitfall can appear seriously, the extensive ground depression that the salt mine exploitation is brought out has all occured in the recent period as Anhui Dingyuan, Jiangxi Zhou Tian and other places, polluted underground water system has caused serious environment pollution.Therefore rationally the discarded salt of disposal chamber has important environment protection significance.Filling industrial residue, oil waste residue etc. can solve waste residue ground and hoard contaminated environment in discarded salt chamber, and the surface settlement after effectively suppressing to exploit is again achieved many things at one stroke.At present, it is blank that domestic research to salt chamber filling still belongs to, have the technical bottleneck that needs to be resolved hurrily in a large number in the backfill construction process, therefore, the device of making one cover energy simulated field salt chamber filling is probed into filling slurry character, placement method and filling process becomes the work of demanding urgently carrying out.
Salt chamber enforcement filling to solution mining formation, usually can adopt following steps: will add the waste residue of flocculation aid and bittern to be deployed into the different filling slurry of concentration on ground according to different ratios, and by the halogen mining pipe road, slurry will be transported in the salt chamber that is full of bittern.At first the filling slurry can spread in bittern after injecting the salt chamber be full of bittern, begins sedimentation after moving in the horizontal direction certain distance, forms the taper precipitation body with certain thickness and angle after sedimentation, and this angle is called the angle of repose.Lateral transfer distance is to weigh the important indicator of filling slurry diffusion, if the lateral transfer distance of filling slurry in bittern is too small, slurry just can't diffuse in the chamber apart from well head distant place, causes obturation can't be full of the salt chamber.The angle of repose is the important indicator of weighing filling slurry effect of settling, if the angle of repose is excessive, needs constantly to promote the inlet pipe mouth during filling, and slurry also can't be full of the salt chamber fully.If obturation can not fully be full of the salt chamber, will seriously undermine the stress distribution that changes country rock by filling, suppress the salt cavity volume and shrink, finally control the purpose of subsidence.So sedimentation, the diffusion phenomena of observation filling slurry in bittern are measured lateral transfer distance and angle of repose, it is the important evidence of research filling effect.In the filling of salt chamber, diffusion, the sedimentation phenomenon of observation slurry are unpractical at the scene, and the lateral transfer distance also can't be measured with the relation of time and the monitored data at final angle of repose.So can set up in the laboratory salt chamber analogue means, the observation slurry spread in bittern, sedimentation phenomenon, measures lateral transfer distance and angle of repose, studies diffusion, the sedimentation character of slurry, the Optimization Packing Method and process.
In filling research, at first to study filling slurry lateral transfer and the angle of repose of variable concentrations.Can add in the filling slurry simultaneously buffer with regulate the filling slurry in bittern lateral transfer and the angle of repose after sedimentation.According to analog result, can determine best filling slurry concentration, best retarding agent kind and addition.

Again, the water-soluble mining type of halite is not quite similar, and there is pair two-chamber that the well exploitation forms in the single chamber that has individual well convection current exploitation to form, and also has because the connection multi-cavity that exhaustive exploitation forms.When difform cavity was carried out filling, it is very large that its Method and process differs, and needs to be treated differently in carrying out filling research.During indoor filling simulation, cavity size needs and on-the-spot cavity size satisfy similarity relation as much as possible, then according to likelihood ratio relation, guide field filling parameters.
The instrument that is used at present analog salt chamber filling yet there are no open report.Thus, the present invention has designed a cover and has measured the device that salt chamber filling is simulated.Use this device and carry out experimental study, variable concentrations be can observe, filling slurry after different content variety classes retarding agent diffusion, sedimentation phenomenon in cavity in the bittern environment added, and can measure the lateral transfer distance of filling slurry and the angle of repose after precipitation, determine accordingly the retarding agent contamination of filling slurry optium concentration, the best.Use this device, can probe into filling process, by regulating filling slurry flow velocity, the pipe end apart from, charging quantity and loading time interval, observe diffusion, the sedimentation phenomenon of different filling process retrofilling slurries in bittern, measure lateral transfer and angle of repose, Optimization Packing technique.Simultaneously, the present invention also can distribute according to on-the-spot salt chamber, and simulation different cavity shape is determined best placement method and technique, for the on-the-spot filling in salt chamber provides technical basis and theoretical the support.
