Description
Technical field
The present invention relates to a kind of combining and put filling coal mining hydraulic support, be particularly useful for that mine comprehensive mechanization Sub-Level Caving filling coal mining work plane carries out supporting, the hydraulic support of mine, put coal and filling simultaneously.
Technical background
The high speed development of China's economic, needs the quick growth of coal production.China's high seam reserves are very abundant, and recoverable reserves accounts for 45% of mine main gross reserves, and the mine main that the whole nation has high seam accounts for 40.6% of mine main sum, widely distributed.
For solving " three times " pressure coal problem, coal mining rate, by adopting traditional Striping noise, resettlement multiple technologies measure liberation such as village, filling mining " three times " pressure coal, improves in China.Combine in recent years and adopt filling technique development rapidly, combine the utilization of adopting filling hydraulic support and substantially increase coal winning technology level.Our discovery in stowing operation is adopted comprehensive, pressure coal coal seam, many collieries " three times " is thicker, have to use separate zone production owing to being subject to combining the restriction of adopting filling mining height, traditional comprehensive filling hydraulic support of adopting cannot normally use, significantly limit coal mining speed and coal recovery rate, realizing comprehensive mechanization Sub-Level Caving filling mining how simply, fast, is efficiently a great problem.Therefore, development is a kind of safeguards coal-face space safety in exploitation work plane technical ability, and the support that can realize again top coal caving and goaf filling is one of key realizing this technology.
Summary of the invention
Technical problem: the object of the invention is the deficiency overcome in prior art, provide a kind of structure simple, easy to operate, pack effectiveness is high, and strong comprehensive of Roof Control ability puts filling coal mining hydraulic support.
Technical scheme: for achieving the above object, of the present invention combining puts filling coal mining hydraulic support, comprise front back timber, be located at the forestope of front back timber front portion, the face guard be connected with forestope, front back timber has front column, central post and quadric chain, front top beam rear end is provided with middle back timber and vertical rack and is located at rear column between base and middle back timber, and the underhung of middle back timber has filling mining conveyer, the base below middle back timber is fixed with the adjustment jack of up-down adjustment pressing device.
Described middle top beam rear end is hinged with the rear back timber can putting coal, and middle back timber and rear back timber bottom are provided with the track for filling mining conveyer slide anteroposterior, are provided with the push cylinder making rear back timber lift or put down between middle back timber and rear back timber.
Described rear back timber comprises casing, is provided with the pull-out box matched with it in casing, and be arranged with the hydraulic cylinder be connected with box inside in pull-out box, casing is provided with pull plate, and pull plate is provided with coal drawing device, and the front end of rear back timber is provided with push plate.
Beneficial effect: combine put filling coal mining hydraulic support not only can the maintenance work face working space of normally mining, can also realize work plane front and mine, coal and the complete filling to goaf are put in rear portion, carry out compacting to obturation simultaneously.Major advantage has:
1., due to three beam structures of front back timber, middle back timber and rear back timber, carrying roof pressure, controls the amount of crushing before filling.
2. in, top beam rear end is hinged with the rear back timber can putting coal, and rear back timber comprises casing, and casing is provided with pull plate, and pull plate is provided with coal drawing device, is provided with the push cylinder making rear back timber lift or put down between middle back timber and rear back timber.Namely can realize pull plate pull meta by coal drawing device and put coal, the low level that can realize again putting down rear back timber puts coal.
3. in casing, be provided with the pull-out box matched with it, the hydraulic cylinder be connected with box inside is arranged with in pull-out box, meanwhile, the front end of rear back timber is provided with push plate, pull-out box coordinate push plate can realize to coal mining space, goaf and put coal space differing heights sold stowing.
4. in, back timber and rear back timber bottom are provided with the track for filling mining conveyer slide anteroposterior, filling mining conveyer can be made along track slide anteroposterior, can realize the filling of attal diverse location, not affect again rear back timber and lift or put down.
