Abstract
The invention relates to a filling reinforcement method for managing an underground mined area of an open-pit mine. The filling reinforcement method is characterized by including the following steps: determining filling drill holes according to the occurrence form of the underground mined area; inserting feeding pipes with trays into the drill holes, inserting grouting pipes in a manner of being spaced by one or multiple feeding pipes, injecting cement mortar, putting granular sand-gravel aggregate into the mined area through the feeding pipes until reaching a top plate of the mined area, and injecting cement mortar through the grouting pipes to form a concrete sandwiched wall in the granular sand-gravel aggregate; finally completing filling reinforcement construction of the whole mined area. The filling reinforcement method has the advantages that strength of a filling body is greatly improved when compared with that of dry filling of loose sand-gravel, deformation and movement of surrounding rock of the mined area can be limited effectively, and satisfactory filling reinforcement effect can be acquired. Compared with grouting cementation filling methods, the filling reinforcement method has the advantages that the defect that layered grouting has quite long construction period can be overcome, so that cost can be saved greatly, and construction efficiency can be improved substantially.
Description
Technical field
The invention belongs to mining technique field, particularly a kind of filling reinforcement means administering opencut Goaf Area.
Background technology
At present, for the old goaf of opencut be detection limit, limit process, the distribution of opencut Mined-out Areas is comparatively complicated, due to a long history, relevant data disappearance, the occurrence status for wherein quite a few old goaf is delphic, often the unpredictable definite position that may subside in advance, thus along with the exploitation of opencut, subsiding of the old goaf of Local topography can cause paroxysmal security incident.
In the method that process Mined-out Areas adopts, filling method is more a kind of method of application.According to the type of goaf filling material is different and the mode of conveying, the filling in goaf can be divided into three kinds of modes.
dry stowing: dry stowing is that namely the loose rubble in goaf, sand, mine tailing, slag etc. do not have cementing material to carry out filling with bulk material as filler.The cost of dry stowing is low, but strength of filling mass is lower, has larger compressible type.
hydraulic fill:water conservancy filling is pumped (conveying) medium with water, utilizes natural pressure head or pump pressure, from preparation station along pipeline or the boring that is connected with pipeline, by material with water profit conveyings such as mountain sand, river sand, broken sand, mine tailings be filled to goaf.In stowing operation, obturation needs dehydration, and needs to build drainage system and discharged by water.
consolidated fill:consolidated fill has certain particle size grating discrete material (such as fine sand, broken building stones etc.) by what process, mix appropriate cementitious material, the mix and blend that adds water is prepared into consolidated fill slurry, the conveying and pouring into along pipeline, boring etc. to goaf, is formed that have a some strength with obturation that is globality.
For guaranteeing safety, opencut Goaf Area forbids personnel to enter, therefore the method being not suitable for adopting water conservancy filling is reinforced in filling, cannot build dehydration and draining that drainage system carries out obturation, and a large amount of water has certain adverse effect for the stability of opencut rock mass slope.The cost of dry stowing is lower, but loose obturation compressibility is larger, and initial compressive strength is very low, to goaf top covering rockmass distortion restriction and support force all undesirable, larger depression can be there is toward contact in earth's surface.Consolidated fill can obtain the intensity of higher obturation, and mechanization of building operation degree is also higher, and filling effect is more satisfactory, but relative higher of filling cost expense, if when needing grouting filling cementing to goaf layering, the cycle of construction is very long.
Summary of the invention
The object of the present invention is to provide one that the layering cementing grouting filling construction period can be avoided very long, the drawback that cost is higher, can save a large amount of costs, increases substantially the filling reinforcement means of the improvement opencut Goaf Area of efficiency of construction.
The object of the present invention is achieved like this, according to a kind of filling reinforcement means administering opencut Goaf Area of the present invention, it is characterized in that comprising the steps:

2) in each filling borehole, plug-in mounting is provided with the commissioning pipe of pallet, and the lower nozzle of described commissioning pipe extend into top board place, Goaf Area;
3) insert Grouting Pipe at interval of in one or several commissioning pipe, the bottom of its Grouting Pipe will arrive the base plate place in goaf;
4) in goaf, prose style free from parallelism sand material is dropped into by each commissioning pipe, until the top board in goaf;
5) then in the sand material of a prose style free from parallelism, cement mortar is injected by Grouting Pipe, grout material is injected in prose style free from parallelism sand material with the form of extruding under the pressure effect of grouting pump, maximum grouting pressure controls at below 2.5Mpa, grout material spreads and is extruded to surrounding by a part of prose style free from parallelism sand material simultaneously in prose style free from parallelism sand material, thus forms an obconic concrete sandwich wall in prose style free from parallelism sand material; The uniaxial compressive strength of its concrete sandwich wall reaches 4.2Mpa, until complete the filling strengthening construction in whole goaf.
Diameter 20mm ~ the 30mm less of bore diameter of described commissioning pipe, the upper orifice position surperficial 80mm ~ 100mm above Ground of commissioning pipe pallet.
The funnel being convenient to the big uncork fed intake is set at described commissioning pipe upper orifice place.
Cement in described cement mortar and the ratio of sand are 1:8 ~ 1:10, and cement is common 32.5
#portland cement, sand is the broken sand of river sand or mountain stone.
The lower end of described Grouting Pipe is the floral tube of porous, and the length of its porous floral tube is 2/3 of goaf height.
Advantage of the present invention is:
Adopt a kind of filling reinforcement means administering opencut Goaf Area of the present invention, the strength ratio of its obturation adopts the dry stowing of loosen loose sand building stones to strengthen greatly, effectively can limit distortion and the movement of goaf country rock, obtain satisfied filling consolidation effect.With slip casting consolidated fill Measures compare, the delamination pour slurry construction period can be avoided very long, the drawback that cost is higher, can a large amount of costs be saved, increase substantially efficiency of construction.
