Description
Technical field
This utility model relates to a kind of longwell spoil strip-type filling coal mining hydraulic support.
Background technology
At present, east China coal field development intensity is higher, most mine residual recoverable reserves seldom, and " three times "
(under building, under water body and under railway) pressure coal amount occupies the major part in residual recoverable reserves.These dull coal money
Source shortens the length of service of mine, limits the development of coal enterprise, these coal enterprise's exigence exploitation " three times "
Pressure coal.
The method of exploitation " three times " pressure coal mainly has post and stall and a method of collecting coal by the means of filling, but post and stall coal
Recovery ratio is relatively low, causes a large amount of wastes of coal resources.The method of collecting coal by the means of filling is by utilizing gangue, flyash the like waste filling
Goaf, the most controllably table sinks but also can utilize garbage in a large number, meets the theory of Green Mine.But for a long time,
The high cost of filling mining and low pack effectiveness seriously limit the popularization and application of filling mining.The part method of collecting coal by the means of filling is led to
Cross reduction pack completeness to reduce filling cost, covert raising pack effectiveness, reduces the defect of the method for collecting coal by the means of filling own and is applied to
Impact.
The strip-type part method of collecting coal by the means of filling has been applied in China's part mining area, but in on-the-spot application, manifold is the most manually constructed
Pack wall or bamboo hedge etc. form strip filling space, and this danger not only adding workman's work also reduces pack effectiveness,
Limit the application of the strip-type method of collecting coal by the means of filling.
Utility model content
In view of this, this utility model provides a kind of longwell spoil strip-type filling coal mining hydraulic support.
The technical solution adopted in the utility model is: a kind of longwell spoil strip-type filling coal mining hydraulic support, by four posts
The gangue stopping device composition of brace type waste filling hydraulic support and band stretchable waste rock stopping plate, wherein said hydraulic support is two sections
Back timber, four hydraulic props back timber hanging drag conveyor waste filling hydraulic support, described gangue stopping device by base, three
Two columns that face around the top waste rock board in the bottom waste rock board, bottom waste rock board of base, is positioned on base long axis and
The back timber composition that column and top waste rock board are connected, the top waste rock board being connected with back timber in described gangue stopping device can be by double
Column controls lifting, fully to connect top.
Described hydraulic support is to be removed ramming device repacking by common waste filling hydraulic support to prepare.Described hydraulic pressure props up
Frame back timber and gangue stopping device back timber are separate.
Described hydraulic support top beam is hinged with front column, rear column and straight guide rod, gangue stopping device back timber and top waste rock board
Weld together and hinged with front column and rear column, front and back's column control lifting.
Described hydraulic support is connected by two hydraulic jacks with gangue stopping device.Described bottom waste rock board is hollow, top
Waste rock board is positioned at bottom waste rock board.
This utility model longwell spoil strip-type filling coal mining hydraulic support, is arranged in longwell waste filling by be spaced
Work surface, in order to form strip filling space, the spacing distance that obturator width is arranged by this utility model determines.Obturator with
The propelling of work surface and extend forward, finally form strip filling body along advance of the face direction.
Of the present utility model having the beneficial effect that realizes the Fully-mechanized of spoil strip-type filling, reduces workman and works by force
Degree, reduces the danger coefficient of workman's work, improves pack effectiveness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (gangue stopping device is in raised configuration).
Fig. 2 is structural upright schematic diagram of the present utility model (gangue stopping device is in half raised configuration).
Fig. 3 is that work surface of the present utility model arranges schematic diagram.
Detailed description of the invention
With embodiment, longwell spoil strip-type filling coal mining hydraulic support of the present utility model is carried out below in conjunction with the accompanying drawings
Describe and explanation.
As depicted in figs. 1 and 2, longwell spoil strip-type filling coal mining hydraulic support, it is characterised in that by four-leg shock
Waste filling hydraulic support and gangue stopping device composition, hydraulic support includes front-axle beam 1, back timber 2, straight guide rod 3, front column 14, stands afterwards
Post 4, hanging drag conveyor 5, base 13 form.Gangue stopping device is by back timber 6, top waste rock board 7, bottom waste rock board 8, rear column
9, front column 10, base 11 form.Described hydraulic support is connected by hydraulic jack 12 with gangue stopping device, described hydraulic support top
Beam 2 and gangue stopping device back timber 6 are separate, and hydraulic support top beam 2 is hinged with front column 14, rear column 4 and straight guide rod 3,
Gangue stopping device back timber 6 welds together with top waste rock board 7 and hinged with front column 10 and rear column 9, front and back's column control
Lifting.Described bottom waste rock board 8 is hollow, and top waste rock board 7 is positioned at bottom waste rock board 8.
13: as it is shown on figure 3, when work surface uses this device, arrange this utility model liquid at work surface open-off cut interval
Pressure support 1,6,7,9, arranges the hydraulic support 2 of band ramming device and without the hydraulic support 8 of ramming device in clearance space,
Spacing distance determines according to field geology conditions and required pack completeness, so at this utility model support 1,9 and 6,7 and open-off cut
It is the formation of filling space between rib, carries out coal mining and filling along with work surface and push ahead, be the formation of strip-type and fill
Fill out body 3,5 and unfilled goaf 4.
