Description
Technical field
The present invention relates to coal mine hydrogeology Exploration Domain.
Background technology
The huge thick limestone of the Ordovician system is developed because of its Karst Fissures, receives Atmospheric precipitation supply fully, dynamic and static rich reserves,
Belong to extremely strong watery artesian aquifer, be often the main resource of water supply in area.
When ground Ordovician karst water source drilling construction is by coal mine gob, isolation processing or processing are not carried out to goaf in time
Improper, brill, which is taken off, tends to occur seepy question behind water-bearing layer, due to drilling the particularity of stratum engineering geological condition, water supply water-bearing layer
There is the characteristics of hydraulic pressure is high, water is big, flow velocity is fast again, make water source drilling particularly difficult by coal mine gob loss zone.And
The strong artesian aquifer water of ash difficult to understand is drilled by water source participates in mine main water-filling along goaf, aggravates draining burden, and with Gao Shui
The continuous erosion damage to hole wall is pressed, water inrush accident is easily caused, seriously jeopardizes mine safety.Leak drilling as handled not in time
Or handle not thorough, the waste of groundwater resources is not caused singly, can also make resource of water supply not enough, gently then can because in hole water supply position add
It is deep and increase water intaking Yang Cheng, increase fees for water supplied and use, it is heavy then cause mine water disaster accident.
One of blocking method commonly used at present：It is to compress to fill in whereabouts water using rubber in drilling, then lapidation is sub, profit
Hydraulic pressure is lived with stone, then carries out cement injection sealing of hole；By underground gushing water discharge observation determine water blockoff success after, further under
Sleeve pipe, slip casting, and cleaning bottom of hole recovers water source drilling.But the shortcoming of this scheme：One is that drilling water outlet unclear location is true, leak paths
Layer position and individual countless, is difficult effectively to block multiple leak paths using the method for lower rubber stopper；Two be to use lower rubber stopper
Method water blockoff, the wall of a borehole easily by High-Pressure Water erosion damage, will increase the difficulty of next step water blockoff；Three be noted stone pole
Easily enter coal mine gob, materials are more, water blockoff claim for eot, closure drilling often results in failure.
The content of the invention
It is an object of the invention to overcome the limitation and deficiency of prior art, using a kind of leak drilling sealing in drilling
Aggregate filter cuts device, and still water buoyancy is overcome by delivering sealing aggregate, aggregate step by step into the sleeve pipe for filtering section device equipped with aggregate
Sink to sleeve bottom, water-bearing layer high pressure move water promote under, force sealing aggregate to be returned along along sleeve outer wall space, aggregate filter
Bottom jib blocks sealing aggregate and carries out leak stopping, then the technical method of ejection for water plugging is effectively treated, and recovers the normal water supply that drills
Efficiency, prevents underground flood damage accident.
Leak drilling sealing aggregate filter of the present invention cuts device, and it is welded one by fixed sleeving, in sleeve pipe appearance
Level aggregate filter bottom jib, the leakage stone aperture of aggregate filter bottom jib are 5mm, and, at a distance of 4m, two grades are welded from eaves under one-level aggregate filter bottom jib
Aggregate filters bottom jib, and aggregate filters the punishment in advance aperture of bottom jib and is welded three-level bone at a distance of 10m for 8mm, two grades of aggregates filter bottom jibs lower eaves
Material filter bottom jib, the punishment in advance aperture of aggregate filter bottom jib is 10mm.The sealing aggregate of leak stopping is different to 10mm different-diameters by 4mm
The stone of shape is made.
Further：The external diameter of aggregate filter bottom jib reduces one-level than boring aperture at leak, it is possible to achieve smooth tripping in drilling
It is interior, and guarantee to play descended sealing aggregate and keep off exactly in complete water proof rock stratum position.
Further：Fixed aggregate filters the casing length of bottom jib, is 1.5 times of leakage strata length, at resistance drilling leak
The hydraulic pressure in born water-bearing layer, and ensure the safety that pressure-bearing drills after sealing.
Further：Leak drilling sealing aggregate filter cuts the position of device, under at 10m below leakage point.
Leak drilling sealing aggregate filter cuts device in use, must take into consideration the pore size around sleeve pipe and hole wall, designs
Suitable aggregate filter bottom jib and the aggregate for selecting appropriate diameter, bet aggregate, it is ensured that institute's sending down the fishbone by the first big after small order of particle diameter
Material is deposited in sealing behind complete water proof rock stratum position exactly, reaches preferable effect.
Beneficial effect
The huge thick limestone of the Ordovician system is developed because of its Karst Fissures, receives Atmospheric precipitation supply fully, dynamic and static rich reserves,
Belong to extremely strong watery artesian aquifer.Ground construction Ordovician karst water source drills, due to drilling the particularity of stratum engineering geological condition,
Water supply water-bearing layer has the characteristics of hydraulic pressure is high, water is big, flow velocity is fast again, and water source drilling passes through coal mine gob loss zone particularly
It is difficult.Employ leak drilling sealing aggregate filter and cut device and application method, described device overall structure is simple, manufactures and installs
It is easy to use, it in bore blocking, can prevent aggregate from largely entering coal mine gob, expected water-stagnating effect is obtained in a short time,
Few using material, substantially, leak stopping sealing reliability is high for down-hole drilling leak plugging effect, and security and stability is good, recovers drilling energy
Normal water supply, success rate is high, it is therefore prevented that underground flood damage accident.
