Abstract
A filling bag for temporarily supporting filling space is applicable to filling along a goaf of pillarless coal mine backstopping tunnels, and comprises a rectangular flexible filling bag. A zipper convenient for operation staff to enter and exit is arranged on the filling bag; and a plurality of small conduits for filling feeding and exhausting are arranged on the top of the filling bag. As the zipper convenient for the operation staff to enter and exit is arranged on the filling bag, the operation staff can conveniently enter the filling space to erect temporary support, and can close the filling bag by closing the zipper after construction. The filling bag can increase roof-contacted rate of filling bodies, and sufficiently perform early bearing characteristics of the filling bodies, and has the advantages of simple structure, convenient operation, safety and high efficiency.
Description
Technical field
The utility model relates to a kind of filling tape, and being particularly useful for the stope of coal mines tunnel does not have the filling bag to filling space realization temporary lining that coal column gob side entry retaining roadside packing uses.
Background technology
Gob side entry retaining is in the mining face under mine exploitation process, by adding methods such as strong supporting, effective roadside support in the lane, former tunnel is remained, make the usefulness in a tunnel of contiguous work plane, its objective is that a tunnel can obtain twice utilization, improved resource recovery, also greatly alleviate digging simultaneously and take over nervous situation, it is that the colliery does not have one of important technology of coal pillar mining, is a major reform of coal mining and stope drift active workings placement technique.Along with the quick propelling that face mechanization is mined, only need every day a class to carry out filling usually, form obturation length at every turn and just can reach 4～5m, need to make corresponding filling bag, but the increasing of filling space is unfavorable for that the top board of filling space is safeguarded.After the working face extraction, roof collapse and string bag situation to occur comparatively common directly influences downhole safety; Just need carry out temporary lining for ensuring safety, can only select open-topped open type filling bag when therefore selecting filling bag filling space complement wood point post.Connect the top weak effect when adopting the filling bag of open type to carry out filling, often only have fraction filling physical efficiency to connect the top, so methods such as the chock buttress of just having to after waiting obturation to solidify at an upper portion thereof connect the top.This method is also wasted raw material such as timber when increasing by a procedure on the one hand; Make on the other hand and stay the lane top board under action of underground, slowly to touch top board, be unfavorable for bringing into play morning, the powerful feature of high percentage of water rapid solidifying material, easily cause the gob side entry retaining failure.
Summary of the invention
The purpose of this utility model is the weak point that will overcome in the prior art, provides a kind of simple in structure, safe and efficient, the filling bag to filling space realization temporary lining that the top board adaptive capacity is strong.
For achieving the above object, the filling bag that the filling space is realized temporary lining of the present utility model, comprise square flexible filling bag, filling bag is provided with a slide fastener of being convenient to constructor's turnover, and the filling bag top is provided with a plurality of ductules that supply the usefulness of filling charging and exhaust.
Described flexible filling bag is made with cloth or cloth; Described a plurality of ductule is four, is distributed on four angles.
Beneficial effect: because filling bag is provided with the slide fastener of being convenient to constructor's turnover, can conveniently enter the filling space and set up temporary lining, construction finishes can be by closing slide fastener sealing filling bag, can improve the top rate that connects of obturation, give full play to the early stage bearer properties of obturation, it is simple in structure, easy to operate, safe and efficient.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-filling bag, 2-slide fastener, 3-ductule.
The specific embodiment
Below in conjunction with accompanying drawing to embodiment of the present utility model is further described:
Shown in the accompanying drawing: filling bag of the present utility model comprises rectangular-shaped flexible filling bag 1, filling bag 1 is provided with a slide fastener 2 of being convenient to constructor's turnover, can conveniently enter the filling space and set up temporary lining, filling bag 1 top is provided with four ductules 3 for the usefulness of filling charging and exhaust, ductule 3 is distributed on four angles, and flexible filling bag 1 usefulness cloth or cloth are made; By closing slide fastener 2 sealing filling bag, connect grouting device by ductule 3 and carry out the filling of high-water material.
The course of work:
(1) require to determine the specification of the filling bag of using 1 according to edge air gallery technology.
(2) the cleaning float coal is put filling bag, open fill bag 1 leading flank slide fastener 2, and the constructor enters filling bag 1 inside temporary lining is set up in the filling space, by wood point post filling bag 1 is propped up.
(3) treat that filling space first row's temporary lining is set up and finish, remove its peripheral unnecessary individual prop, then set up second row's temporary lining, all temporary linings are pulled on filling bag slide fastener 2 after setting up and finishing, and set up filling bag 1 all cheek boards.
(4) after template erection finishes filling pipe is inserted in the arbitrary ductule 3 that filling bag 1 reserves (all the other ductules are as the usefulness of exhaust), carries out formal filling.
Claims (3)
1. filling bag that the filling space is realized temporary lining, it is characterized in that: it comprises square flexible filling bag (1), filling bag (1) is provided with a slide fastener (2) of being convenient to constructor's turnover, and filling bag (1) top is provided with a plurality of ductules (3) that supply the usefulness of filling charging and exhaust.
2. the filling bag to filling space realization temporary lining according to claim 1, it is characterized in that: described flexible filling bag (1) is made with cloth or cloth.
3. the filling bag to filling space realization temporary lining according to claim 1, it is characterized in that: described a plurality of ductules (3) are four, are distributed on four angles.
