Description
Technical field
The utility model relates to a kind of Novel thin coal seam filling hydraulic support.
Background technology
Due to the continuous prolongation of mine service-life, mine resource is close to exhausted, and village presses down coal problem and becomes increasingly conspicuous.Faced with this situation, for accelerating the transformation of coal mining mode, " three times " mining pressed coal is classified as emphasis key scientific and technological projects.China's medium-thickness seam filling mining technology maturation, has developed filling support, applies work plane filling support, achieve good result in Xingtai Coal Mine, Ji Sankuangdeng unit.Also with good grounds work plane coal winning technology have developed filling machine and realizes work plane filling.But be all be applied to medium-thickness seam, and girdle does not also have the example of work plane filling support at present both at home and abroad.Because thin seam working surface mining height is low, pedestrian's difficulty, operation control system requires that reliability, automaticity are low, the reasons such as labor strength is high, mining level is relatively low, and benefit is poor, pack effectiveness is low, and safety guarantee coefficient is little, installs stowage unit difficulty.Solve the technical research of girdle filling mining technology and equipment, to raising pack effectiveness, widely popularize girdle filling mining technique, liberation " three times " pressure coal will have very important effect.Realize lasting exploit, solve the meaning owing to exploiting surface subsidence etc. with decision.
At present, both at home and abroad on girdle filling and support, mainly contain: individual prop or waste edge chock; And the girdle filling bracket domestic example also not having successful implementation at present.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned defect how overcoming prior art, provides a kind of Novel thin coal seam filling hydraulic support.
For solving the problems of the technologies described above, filling hydraulic support in this Novel thin coal seam comprises coal mining support and filling support, wherein be connected by oil cylinder of walking between coal mining support with filling support, filling support comprises back timber, folding spy beam and hydraulic lifting post, coal mining support comprises back timber and four hydraulic lifting posts, hydraulic lifting post lower end is provided with base, filling support rear portion is provided with retractable blinds, described telescopic baffle comprises overhead gage, middle baffle plate and lower baffle plate, wherein overhead gage is fixed on back timber or the hydraulic lifting capital end of filling support, lower baffle plate is fixed on hydraulic lifting post bottom or base, overhead gage also has vertical chute, described middle baffle plate is provided with pin, and be suspended in the vertical chute on overhead gage by this pin, filling frame back timber is provided with needling, upper needling surrounding is provided with reinforcement gusset, the top of the hydraulic lifting post of filling frame is just inserted in upper needling.
When face height changes, while support height change, telescopic baffle adjusts automatically, and make filled wall form enclosure space, lotion can not flow out.Lower baffle plate and bracket base with bolts, middle baffle plate is in the middle of upper lower baffle plate, and along with the filling of lotion, baffle plate does not move after the meeting, makes filling solid, and simultaneously baffle plate is recoverable to, and facilitates transporting bracket.Baffle plate leaves filling mouth, and workman can enter work plane rear portion and carry out filling by filling mouth from the pedestrian space between support.
Filling support front and rear part adopts walking oil cylinder bindiny mechanism, passes very heavy very heavy fixing with on same base with front portion, compact conformation.Save space, the rugged situation of base plate can be adapted to simultaneously.
As optimization, the back timber of described coal mining support is integral top beam.Integral top beam structure, set cap is that integral top beam structure is anterior with extensible canopy structure, and flexible stroke 800mm, can adopt top board to anterior big gun and carry out advance support.
As optimization, the back timber of described coal mining support is divided into front and back two parts, is erected on forward and backward hydraulic prop respectively, is connected with articulated linkage between the two parts of front and back.Split beam structure is hinged top girder construction, and before and after back timber, two parts are formed by connecting by junction plate, increases pedestrian space, has played adaptation top board and passing fault ability high simultaneously.Filling support in rear portion is used for the supporting of rear portion top board and the control of filled wall, and support is provided with wall supporting structure, can carry out necessary supporting, ensure the safe space of fill area operation to workman fill area.
As optimization, four hydraulic prop lower ends of described coal mining support are separately fixed on front base and rear base, are provided with the plate that is articulated and connected between front base and rear base.Filling support height 600 ~ 1200mm, when minimum mining height 800mm, operative space is very limited, adopt anterior base and rear portion base by junction plate interconnection system flexible structure, at the upper place mat being covered with polyurethane above it, both increase manipulation and pedestrian space, human oriented design simultaneously, and prevent workman from operation or walking process, occurring phenomenon of colliding with.
Filling hydraulic support in this Novel thin coal seam, using filling mining technical research and application as breach, by investigating demonstration and research of technique fully, have developed girdle filling support.
The main feature of this girdle filling support is when coal seam thickness is lower, front portion is carried out big gun and is adopted coal breakage, paste body filling is carried out at rear portion, the difference according to face roof situation adopted by big gun, is designed with radial type and monolithic beam structure, and filling utilizes the spoil produced in shaft production, after break process, interpolation flyash and water stir, and stir the Paste-like body waste filling material of preparation, are fills up to goaf carry out filling by spoil pump through filling pipeline.The problems such as this filling support meets the supporting requirement of work plane, achieves the filling of full face, solves thin seam working surface space little, pedestrian's difficulty, improve pack effectiveness, are applicable to girdle filling mining.
