Abstract

The invention provides a method for fixing a gob-side entry retaining roadside packing body on a coal seam with a big declined angle, which is applicable to fixing the gob-side entry retaining roadside packing body under the condition of big declined angle(the declined angle(alfa) of the coal seam is more than 15 degrees). Fixing pull rods are fixed in the roadside packing body which is constructed in sections at intervals and simultaneously fixed on a groundsill on the side of the gob-side entry retaining, and anchoring heads of the fixing pull rods are closely fixed on bottom plates on the side of a goal area by an anchoring agent; and along with the advance of a coal face, the construction of the roadside packing body and the fixing pull rods is orderly and cyclically performed until the whole gob-side entry retaining operation is completed. By the method, the gob-side entry retaining bottom plates of the coal seam with a big declined angle are unnecessarily flattened, and the fixing pull rods only need to be arranged at intervals along the direction of constructing the packing body on the declined surface, by the combined action of the fixing pull rods and front baffle boards, the packing body is effectively restricted or blocked from slipping down; moreover, the method also has the advantages of simplicity, easy construction, time and labor conservation, good effect and wide practicability.

Description

The fixing method of gob-side entry retaining of large-inclination coal seam roadside packing body
Technical field
The present invention relates to edge air gallery technology, especially a kind of fixing method of gob-side entry retaining of large-inclination coal seam roadside packing body.
Background technology
Under the situation of seam inclination big (α>15 °), gob side entry retaining roadside packing body just is difficult to stablize.Subject matter is, obturation places on the inclined-plane, and under the multifactor actings in conjunction such as extruding of obturation self gravitation, overburden pressure and the spoil that collapses, obturation causes the obturation unstability just to lower slider.Aspect the control of existing gob side entry retaining roadside packing body stability, also there is not solution well at present.In order under high inclination-angle (α>15 °) situation, to implement the gob side entry retaining roadside packing, adopt and will carry out filling again after the inclined-plane leveling, the amount of working is quite big like this, has not only had a strong impact on the progress of filling operation, and has influenced the production of work plane.
Summary of the invention
The objective of the invention is at the problem that exists in the prior art, provide a kind of method simple, easily construction, workload is little, can directly carry out the fixing method of gob-side entry retaining of large-inclination coal seam roadside packing body.
Technical scheme of the present invention is:
A, adopt the sky side in tunnel, work plane rear the gob-side entry retaining of large-inclination coal seam piecemeal is constructed the roadside packing body;
B, whenever finish a roadside packing body, along boring an anchor hole on the base plate of goaf one side at least downwards, and in anchor hole, put into the anchoring agent at the roadside packing body;
C, the firm pull bar of corresponding hole count is inserted in the anchor hole, be fixed in the anchor hole after fully stirring with the anchoring agent;
D, carry out constructing of next piece roadside packing body, firm pull bar is fixed between two sections roadside packing bodies, with front baffle board and nut that the afterbody of firm pull bar is fastening;
E, along with the propelling of coal-face, constructing of circulation construction roadside packing body and firm pull bar successively is until finishing whole gob-side entry retaining work.
Described firm pull bar is 1~3.
Beneficial effect: no longer need the gob-side entry retaining of large-inclination coal seam base plate is flattened, only need on the inclined-plane, fixed interval has the firm pull bar that is fixed in simultaneously along on the one side base plate of goaf in the roadside packing body that piecemeal is constructed, the anchorage head of firm pull bar is anchored on the ground of goaf one side by the anchoring agent, acting in conjunction by anchoring rod and front baffle board, effectively suppress and stop that obturation is in the inclined-plane slide down, obturation is stable on the inclined-plane, promptly under the effect of anchoring rod, obturation and inclined-plane are become one, can improve the stability of obturation greatly, the assurance gob side entry retaining is unimpeded, and this technology is applicable to implements gob side entry retaining roadside packing technology under high inclination-angle (seam inclination α>15 °) condition.This technology can alleviate labor strength greatly, has improved efficiency, makes gob side entry retaining work not influence the work plane coal mining activity.Its method is simple, and easily construction is time saving and energy saving, effective, has practicality widely.
Description of drawings
Fig. 1 is a construction schematic diagram of the present invention.
Fig. 2 is the A-A generalized section of Fig. 1.
Among the figure: the firm pull bar of 1-; The 2-front apron; The 3-anchor hole; 4-anchoring agent; The 5-anchorage zone; 6-roadside packing body; The 7-spoil that falls that collapses; The 8-goaf; The 9-force piece; 10-file leader's frame; Former tunnel, 11-work plane the place ahead; The 12-gob side entry retaining; The 13-roof; The 14-seat earth; 15-coal seam or coal group.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
Shown in the accompanying drawing, propelling along with work plane, force piece 9 moves forward with file leader's frame 10 thereupon, the filling space is reserved at rear at file leader's frame 10, at this moment adopt the sky side in the tunnel and 13 construct roadside packing body 6, with top board 13, base plate 14 and coal seam or the coal group 15 common gob side entries 12 that form from seat earth 14 to roof.Whenever finish a roadside packing body 6, at roadside packing body 6 along boring a hole on the base plate 14 of 8 one side anchorage zones 5, goaf at least downwards, according to on-site actual situations, firm pull bar 1 can be 1, it also can be 2 or 3, improve the stability of obturation on the inclined-plane with this, satisfy the requirement of gob side entry retaining.In boring, put into anchoring agent 4, firm pull bar 1 is inserted in the anchor hole 3, fully be fixed in the anchor hole 3 after the stirring with anchoring agent 4, carry out constructing of next piece roadside packing body 6, firm pull bar 1 is fixed between two sections roadside packing bodies 6, with front baffle board 2 and nut that the afterbody of firm pull bar 1 is fastening; Obturation is stable on the inclined-plane, promptly under the effect of anchoring rod, obturation and inclined-plane are become one, propelling (work plane the place ahead former tunnel 11 shortenings along with coal-face, gob side entry retaining 12 lengthenings), circulation construction roadside packing body 6 and firmly constructing of pull bar 1 successively are until the operation of constructing of finishing whole roadside packing body.When the spoil 7 that falls when collapsing was squeezed in roadside packing body 6 inboards, the firm pull bar 1 that is anchored on the one side base plate of goaf, inclined-plane was combined closely with roadside packing body 6, and roadside packing body overall structure stability is improved greatly.
