Abstract
The utility model discloses a gob-side entry retaining end hydraulic support, which comprises end supports. A gob-side entry retaining template assembly which is equipped on the outer side of the outermost end support comprises an upper template and a lower template. The upper template is fixed on the top beam of the end support while the lower template is fixed on the base of the end support. The upper template and the lower template are in movably overlapping joint relation. During a coal mine exploitation process, a tunnel filling template is equipped inside a tunnel of an exploiting working face. Filling operations are performed between the gob-side entry retaining template assembly and the tunnel filling template. A new tunnel which is retained along a goaf is applied as a tunnel for exploiting a next working face. The gob-side entry retaining end hydraulic support which has high formwork efficiency and high safety saves the trouble of reserving coal pillars on working faces and improves the coal resource recovery rate and the working face advancing efficiency.

There is shortcoming at least in above-mentioned prior art:
Coal recovery rate is low, tunnelling rate height, cost of production height, advance of the face efficient are low.
The utility model content
The purpose of this utility model provides a kind of formwork efficient and safe, can improve the gob side entry retaining end hydraulic support of coal recovery rate and advance of the face efficient.
The purpose of this utility model is achieved through the following technical solutions:
Gob side entry retaining end hydraulic support of the present utility model, comprise face end support, the outside of described face end support is provided with the gob side entry retaining template assembly, described gob side entry retaining template assembly comprises cope match-plate pattern, lower bolster, described cope match-plate pattern is fixed on the back timber of described face end support, described lower bolster is fixed on the base of described face end support, movable overlap joint between described cope match-plate pattern and the lower bolster.
The technical scheme that is provided by above-mentioned the utility model as can be seen, the gob side entry retaining end hydraulic support that the utility model provides, because the outside of face end support is provided with the gob side entry retaining template assembly, propelling along with coal-face, can carry out roadside packing by template assembly, stay the tunnel along the goaf, as the tunnel of the next work plane of exploitation.Formwork efficient and safe has been saved the coal column that work plane is reserved, and has improved coal recovery rate and advance of the face efficient.
Description of drawings
The structural representation of the gob side entry retaining end hydraulic support that Fig. 1 provides for the utility model embodiment;
The floor map that the gob side entry retaining end hydraulic support that Fig. 2 provides for the utility model embodiment carries out gob side entry retaining coal mining.
Among the figure:
1, face end support back timber, 2, cope match-plate pattern, 3, middle template, 4, lower bolster, 5, the face end support base;
11, former tunnel center line, 12, the gob side entry retaining template assembly, 13, the tunnel filling template, 14, new tunnel, 15, obturator, 16, face end support, 17, the middle transition support.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Gob side entry retaining end hydraulic support of the present utility model, its preferable specific embodiment be as shown in Figure 1 and Figure 2:
Comprise face end support, the outside of described face end support is provided with the gob side entry retaining template assembly, described gob side entry retaining template assembly comprises cope match-plate pattern, lower bolster, described cope match-plate pattern is fixed on the back timber of described face end support, described lower bolster is fixed on the base of described face end support, movable overlap joint between described cope match-plate pattern and the lower bolster.
Be provided with middle template between described cope match-plate pattern and the described lower bolster, reach movable overlap joint between described middle template and the lower bolster between described cope match-plate pattern and the middle template.
Comprise three frame end head brackets, the outside of the face end support of outer end is provided with described gob side entry retaining template assembly in the three frame end head brackets.
Described three frame end head brackets are provided with the anti-skid device, and described anti-skid device comprises drag-line, and an end of described drag-line is fixed on the back timber of face end support of outer end, and the other end of described drag-line is fixed on the base of inner face end support.
Also comprise anchor device, on the fixing described lower bolster of an end of described anchor device, the other end tension of described anchor device is on the base of the face end support of the inner.
Use the method that above-mentioned gob side entry retaining end hydraulic support of the present utility model carries out gob side entry retaining coal mining, as shown in Figure 2:
In the process of coal mining, in the tunnel of exploitation work plane, the tunnel filling template is set, carry out filling between described gob side entry retaining template assembly and described tunnel filling template, stay new tunnel along the goaf, described new tunnel is as the tunnel of exploiting next work plane.
The backfill of filling usefulness can form for ashes and the cement mixing from power plant, can adopt spoil to make the roadside support material.
The utility model is blended in filling process in the coal winning technology, at arranged outside cope match-plate pattern, middle template and the lower bolster of the face end support of outermost end, and three frame end head brackets design anti-skid device.Form the filling space after moving frame, improve formwork efficient and safety by the quick formwork erection of mechanization.
Use edge air gallery technology of the present utility model, the colliery is along with the propelling of coal-face, adopt the roadside packing method, stay the tunnel along the goaf, all can be used as the crossheading of the next work plane of exploitation along the empty tunnel that stays, following crossheading will become the last crossheading of next work plane subsequently, can be maintained by the backfill of certain width (as 3 meters).One lane is dual-purpose, saves the expense of digging laneway, avoids debalance of preparation and winning work, anxiety continues;
Gob side entry retaining has saved the coal column that work plane is reserved, and raising coal recovery rate, reduction tunnelling rate, the digging tight relationship of alleviating, realization mine intensification production are had remarkable result.Reduce production costs, adapt to the needs that the high-yield and high-efficiency work plane advances fast.
In concrete the application, can select backfill pump or miscellaneous equipment for use, carry out edge the fast continuous filling in lane of leaving a blank.Backfill is for mixing by certain ratio from power plant's ashes (or other article) and cement.The siccative of backfill feed bin is delivered to down-hole transitional storehouse (surge bunker) by compressed air piping.Mix the station in emulsification, mix the back with water and be pumped to the back filled region by hydraulic concrete.The paste body filling material, pumps in the filling template under the effect of high-pressure pump by pressure piping, solidifies the back and forms filled wall; Can adopt spoil to make the roadside support material, can gather materials on the spot, both can reduce pick lane cost and spoil cost of transportation, can reduce soil, minimizing environment pollution that hillock takies again, have very extensive applicability.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
