Description
Technical field
The utility model relates to a kind of boring high pressure and to metal run out device for plugging, in particular device at the bottom of a kind of anti-blockage holes.
Background technology
Slip casting technology of harnessing the river threatens the important channel in coal seam as liberation by water, feasible, the economical rationality of possessing skills, safe and reliable feature, and its scope of application is very wide, shutoff can be destroyed the water flowing fractured zone and conduit pipe that cause by various geological structure; Can aquifer be transformed, make it to become aquitard; Primary and the secondary space of water barrier, crack can be reinforced, make it to become the fluid-tight rock mass that blocks water.
Grout transformation changes method and the means of rock mass (layer) hydrogeological conditions as a kind of will by people, general principle is slurries dehydration in the space originally occupied by water by note layer or passage, consolidation or gellings under certain pressure, certain hour effect, make Seed harvest or gel and Rock Mass form the entirety that blocks water, thus change the hydrogeological conditions being unfavorable for digging up mine.Aquifer transformation can be played to the slip casting of thin layer limestone, effect that water producing fractures shutoff and water barrier are reinforced:
(1) to a large amount of reperfusion serosity of thin layer limestone, slurries along Karst Fissures diffusion, calculus, filling, the water " displacement " in aquifer out, make it not moisture or weak moisture at thin layer limestone.
(2) slurries are under grouting pressure effect, by thin layer limestone along the migration of Ordovician karst water supply thin layer limestone passage, diffusion, calculus, block or reduce conduit pipe, reducing the increment of Ordovician karst water.
(3) slurries are under grouting pressure effect, by thin layer limestone along the migration of seat earth crack, diffusion, calculus, and filling water barrier water producing fractures, strengthening, thickening seat earth.
The seam mining water damage control waterborne of high bearing bottom plate mainly contains two kinds of methods, that is: Draining hook and mining under safe waterpressure of aquifer.But dredge that to fall exploitation be with good conditionsi, for moisture abundant, nourishment condition is good, the artesian aquifer that head is high, as taked Draining hook measure, one is that the electric lighting bill is heavy in draining, and two is after coal seam has been adopted, and still need long-term draining, economy is extremely unreasonable.Meanwhile, can dredge for some aquifer and fall, but dredge scale of falling also by the restriction of mine drainage ability.Not only waste water resource, and affect production and take over, seriously restrict manufacturing schedule.Current coal mining mainly adopts floor undulation grouting and reinforcing and renovation technique, increases seat earth effective water-resisting layer thickness, administers the too grey water damage danger side of body of base plate high pressure-bearing, guarantees Safety of Coal Mine Production
Floor undulation limestone water damage preventing and controlling flow process is: work plane hydrogeological conditions pre assessment → physical prospecting engineering → govern compositive designs → drill slip casting (unrestrained water) engineering construction → quality examination (inspection eye, physical prospecting) → security evaluation.
Govern compositive design is the basis carrying out govern compositive, and the quality good or not of govern compositive design directly affects the construction safety of govern compositive, working measure and construction quality and construction effect.Therefore govern compositive designing requirement will have higher water prevention theoretical level and have the technician of abundant site operation experience to come, and understands construction condition completely, grasps the technical level of constructor and the equipment performance of use.Govern compositive design not only requires the reasonability of engineering design, science and operability in macroscopical, and require in each link and details is complete, safety, science, reasonable and can operate.
Carry out floor grouting transformation mine and all have surface grout injection station, each drill site is for slurry to down-hole to utilize surface grout injection station, and each ore deposit grouting pipeline reaches more than 10000 meter, and circuit failure (as blocking, spillage etc.) phenomenon occurs often.Wherein pipeline blockage deals with very because of difficulty, if processed not in time, the cement paste in flow inlet will solidify in pipeline, causes whole flow inlet road to scrap.The pipeline dredging can will solidified exactly, needs a large amount of manpower of cost and time, have impact on normal slip casting work, lose larger.
Slip casting material transport hole is the defeated slurry boring of leading to down-hole from ground, its inwall is the steel pipe of φ 89mm, and in long-term slip casting process, its inwall can deposit the same laitance coating of some similar incrustation scales, naturally come off or when by after coming off when extraneous vibration, fall into blocking pipeline at the bottom of hole.
