Abstract
The utility model discloses a height adjustable gob-side entry retaining filling bag which mainly comprises two identically the same filling bags, wherein each of the two filling bags is a cuboid cloth bag with the top surface opened, the four corners on the bottom surface of each filling bag are respectively fixed with bottom ejection plates of an entry, the two identically the same filling bags are mutually nested through openings in the top surfaces to form the height adjustable filling bag, and the length of the mutually nested part of the two filling bags is determined according to the height of the entry, as a result, the normal filling in the range at most twice that of the design height of the entry can be implemented so as to enable the filling bag to be completely jointed with a top plate. The utility model relates to the gob-side entry retaining filling bag for a mine, which eliminates the potential danger that harmful gas overflows in a gob area because the height of a roadway is changed and a roadside filling body cannot be completely jointed with the top plate, and ensures the safety and the maneuverability of a gob-side entry retaining technology. The height adjustable gob-side entry retaining filling bag is exquisite and reasonable in design, simple in operation, easy in implementation, and wide in application on the aspects of overall pouring of the gob-side entry retaining roadside filling body in coal-pillar-free exploitation of a mineral well.
Description
Technical field
The utility model relates to a kind of filler for mine bag, and the adjustable gob side entry retaining filling bag of especially a kind of height is used under the coal mine without coal pillar mining roadside support technology.
Background technology
Gob side entry retaining will become the main arrangement form of coal stope drift active workings as a main development direction without coal pillar mining.For a long time, integrated poured possibility and the simple and efficient of operating procedure of roadside packing body is the principal element of its all-round popularization of restriction always.Traditional cast template is because the dismounting complexity directly has influence on the back production progress; The opened type filling bag is owing to can not engage the effect that top board can't play isolated goaf pernicious gas fully.Closed filling bag connects in the operating procedure profit that tool is greatly improved aspect the effect of top, but because size is fixed, height cannot be adjusted, thereby often can't engage top board fully when causing the stope drift active workings superelevation owing to reasons such as roof collapse or mining height increasings and cause goaf air leaking when running into, exist goaf gas and other pernicious gases to the excessive potential safety hazard in stoping operation space.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of height-adjustable function that has, and guarantees that the roadside packing body can be according to the gob side entry retaining filling bag of stope drift active workings Height Adjustment.
Technical scheme: a kind of adjustable for height gob side entry retaining filling bag of the utility model, comprise two identical filling bag of size, described filling bag is the uncovered cloth bag of the cuboid of end face opening, and filling bag is fixed on the roof and floor of stope drift active workings by four annulus of sole arrangement; The filling bag that described two sizes are identical is passed through the adjustable for height filling bag of the mutually nested formation of end face opening, adjusts the packed height of whole filling bag by the length of the mutually nested part of control filling bag; During practical operation one of them filling bag is fixed with iron wire by four jiaos annulus along the stope drift active workings base plate, opening up; Another filling bag hangs with iron wire along the annulus of stope drift active workings top board by four jiaos of sack bottom surfaces, and is opening down.Two filling bag nest together use, determine filling bag nested parts length according to the stope drift active workings height, and maximum can realize the normal filling in the twice stope drift active workings design height scope.
Beneficial effect: the utility model is applied under the coal mine in the non chain pillar entryprotection technology, specifically be applied in this integrated poured system of gob side entry retaining roadside packing body of protecting the lane technology, can realize that by adjustable for height gob side entry retaining filling bag obturation is not subjected to the stope drift active workings height restriction, the filling bag of fixed dimension can't closely engage top board in the stope drift active workings superelevation situation of having avoided causing owing to reasons such as roof collapses, can not play the effect of isolated goaf gas and other pernicious gases.Eliminated the excessive potential danger to normal stoping operation space of pernicious gas.Adjustable for height gob side entry retaining filling bag compact conformation, deft design is reasonable, simple to operate, has widely practicality aspect integrated poured without coal pillar mining gob side entry retaining roadside packing body under coal mine, can effectively guarantee to stay the lane filling effect, filling process is simplified, thereby engaged the isolated goaf gas of top board and other pernicious gases fully.

The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Shown in Figure 1, a kind of adjustable for height gob side entry retaining filling bag of the utility model, comprise two identical filling bag 1 of size, filling bag 1 is for being provided with the cuboid cloth bag of end face opening 2, and four annulus 3 that filling bag 1 is arranged by the bottom are fixed on the roof and floor of stope drift active workings.The height of filling bag 1 is identical with the height of stope drift active workings.
Shown in Figure 2, the identical filling bag 1 of two sizes consists of adjustable for height filling bag by end face opening 2 is mutually nested, adjusts the height of whole filling bag by the mutually nested length of control filling bag.
Claims (3)
1. an adjustable for height gob side entry retaining filling bag comprises two identical filling bag of size; It is characterized in that: filling bag is the uncovered cloth bag of the cuboid of end face opening, and filling bag is fixed on the stope drift active workings roof and floor by the annulus of four jiaos of bottom surfaces.
2. adjustable for height gob side entry retaining filling bag according to claim 1 is characterized in that: the identical filling bag of described two sizes is by the adjustable for height filling bag of the mutually nested formation of end face opening.
3. adjustable for height gob side entry retaining filling bag according to claim 1, it is characterized in that: the height of described filling bag is identical with the stope drift active workings design height.
