The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Gob side entry retaining end hydraulic support of the present invention, 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.
The method that the above-mentioned gob side entry retaining end hydraulic support of application of the present invention carries out gob side entry retaining coal mining, its preferable specific embodiment be 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 present invention 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 invention, 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; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
