Abstract
A gob-side retained entry reinforcing fill structure comprises a filling bag, a plurality of small top bags are arranged at intervals on the top edge of the filling bag, a plurality of small lateral bags are symmetrically arranged at intervals on two lateral sides of the filling bag along the filling direction, counter-pulled anchor bolts penetrate through the small lateral bags, a plurality of hooks are arranged at intervals on the top and the periphery of the filling bag, and a form protective reinforcement fabric fixed by steel wires is arranged around the filling bag. Before filling, the counter-pulled anchor bolts penetrates into the small lateral bags which are bound with iron wires, nuts are fastened after trays are set, the filling bag is inflated fully for roof contact by the aid of grout outlet pressure of a filling pump during filling, anchoring force of the anchor bolts is screwed to a preset value after certain strength of a fill is achieved, and thereby filling and fill reinforcement are realized at one step. The gob-side retained entry reinforcing fill structure is simple in structure and convenient in construction.
Description
Technical field
The utility model relates to down-hole mechanicalization and constructs roadside packing body technique field, and especially a kind of gob side entry retaining of the heavily stressed mine in deep that is applicable to is reinforced the obturation structure.
Background technology
Gob side entry retaining is that twice utilization done in a tunnel, greatly improves resource recovery, alleviate digging and take over anxiety, and be a major reform of coal mining and stope drift active workings placement technique.After entering deep mining, the ore deposit is pressed and to be manifested aggravation, directly contracts obviously in the tunnel, the large deformation of gob side entry retaining obturation, carrying occur and loses efficacy increasingly, and the obturation destruction that does not particularly connect the top is even more serious.Therefore, to connect top effect and supporting filling body be crucial to the gob side entry retaining roadside packing.The common way of mechanization filling in the past is: 1, beat firm individual prop supporting filling space in the periphery, filling space earlier, install filling template again, then suitable filling bag is put into template, hang up filling bag, make the filling bag bottom be shaped the turn on pump filling; 2, in stowing operation, every filling certain altitude, on carry the primary filling bag, avoid filling bag tenesmus to crumple.During filling, add a template or wooden adjusting template again when increasing near the template upper end gradually etc. slip in the filling bag, the said process that so circulates, up to filling bag be full of connect the top till; 3, treat that obturation is solidified after, pull down template, then on obturation jewel hole, linked network, install drawing anchor pole to reinforce obturation.
The shortcoming or the need improvements that use this mode to exist be: 1, because mining face under mine top board complicated condition, after work plane is adopted, situations such as top board injustice (or face upward tiltedly or bow tiltedly), inbreak and the string bag are comparatively common, connect the top weak effect when adopting the filling bag of open type, often only there is fraction filling physical efficiency to connect the top, the mode such as chock buttress of just having to after waiting obturation to solidify at an upper portion thereof connects the top, wastes raw material such as timber on the one hand; Make on the other hand and stay the lane top board under action of underground, slowly to touch obturation, the bearing pressure peak value of coal group side is shifted to coal seam depth, can not bring into play powerful feature morning of filler, easily cause the gob side entry retaining failure; 2, filling and reinforcing obturation are implemented in two steps, operation is cumbersome, can when filling, implant anchor pole in advance by reinforcing the obturation requirement, treat to tighten anchor-holding force of anchor bolt again to preset value after obturation reaches certain intensity, so just reduced operations such as setting up, tear open imperial template, linked network and boring skyhook, realized filling and reinforce obturation settling at one go.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of gob side entry retaining simple in structure, that operations such as imperial template, linked network and boring skyhook are set up, torn open in minimizing to reinforce the obturation structure.
Gob side entry retaining of the present utility model is reinforced the obturation structure, comprise filling bag, the top of described filling bag is interval with several top pouch, filling bag is arranged with several side pouch at interval along filling direction two sides, and be provided with pass the side pouch to drawing anchor pole, the top of filling bag and peripheral intervals are provided with some hooks, be provided with around the filling bag with iron wire fixing protect the mould steel mesh reinforcement.
Beneficial effect: the utility model is made the rectangular-shaped of sealing with filling bag, make several pouch in the filling bag top with along filling direction two sides same position (by reinforcing the obturation requirement), top pouch is for the usefulness of filling charging and exhaust, and the side pouch is put on drawing anchor pole to make to reinforce the usefulness of obturation; Again in filling bag top center zone with on lateral side wire around the spacing distance of filling bag top, sew on the hook of certain density, hook is hung over filling space top board or all around, use steel mesh reinforcement allow obturation moulding and oppose and draw the usefulness of bolt anchorage obturation wall supporting as filling template.Changed the operation that gob side entry retaining is implemented filling and reinforcing obturation in two steps, it is simple in structure, easy to operate, the construction of favourable down-hole, the mechanization pumping is constructed fast reinforce obturation when gob side entry retaining obturation structure is closely knit to connect the top, realize the closely knit supporting that connects the top and reinforce obturation.Compared with prior art, at first be to make the closely knit top that connects of casting resin, realize the early stage bearer properties of filler, prevent absciss layer, cut off the goaf and directly push up; The 2nd, construct and reinforce obturation when obturation is closely knit to connect the top, reduce and set up, tear open operations such as imperial template, linked network and boring skyhook; The 3rd, do not destroy the integrality of obturation, reduce adopt the sky side protect the top width degree temporarily, more help gob side entry retaining; The 4th, simple to operate, good reliability reduces filling cost, has practicality widely in the present technique field.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the I-I section structure schematic diagram of Fig. 1.
Fig. 3 is the partial enlarged drawing of Fig. 2.
Among the figure: the 1-filling bag, 2-protects the mould steel mesh reinforcement, the 3-iron wire, the 4-hook, 5-is to drawing anchor pole, 6-top pouch, 7-nut, 8-pallet, 9-side pouch.
The specific embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:
Shown in the accompanying drawing, gob side entry retaining of the present utility model is reinforced the obturation structure, comprise the rectangular-shaped filling bag 1 of making sealing, the top of filling bag 1 is interval with several top pouch 6 for the usefulness of filling charging and exhaust, filling bag 1 is arranged with several at interval and wears drawing the side pouch 9 of anchor pole 5 along filling direction two sides, to drawing anchor pole 5 to pass side pouch 9, its two ends is equipped with pallet 8 and nut 7 respectively, the top of filling bag 1 and peripheral intervals are provided with some hooks 4, are provided with around the filling bag 1 with what iron wire 3 was fixed and protect mould steel mesh reinforcement 2.Before filling, put in the pouch from the side drawing anchor pole, bind side pouch 9, first-class pallet 8, tightening nuts 7 with iron wire 3; Utilize the grout outlet pressure of filling pump during filling, filling bag is heaved fully touched face roof coal or rock stratum; Treat to be screwed to preset value to drawing anchor-holding force of anchor bolt after obturation reaches certain intensity, filling and one step of reinforcing obturation are realized.
