Description
Technical field
The utility model relates to mine worked-out section filling technique, refers to the system utilizing crude tailings lotion to carry out filling dehydration especially.
Background technology
Mining activity often causes massif inside built on stilts, and in order to prevent subsidence, need to carry out filling process to mine worked-out section, crude tailings paste body filling is conventional filling way.Crude tailings paste body filling is filled in mine worked-out section by plant equipment by lotion or Paste-like body tailings, supports mine massif conversely, thus reach the object preventing subsidence after its dehydration, sclerosis.The lotion that stowing operation is used or Paste-like body tailings are the high concentration last mortars that concentration is greater than 70%, its water content about 30%, and lotion tailings could be pressed after only having fully dehydration stable with effectively controlling dead zone, and therefore the dehydration of crude tailings lotion is very important link.
Non cemented filling technology is the one in crude tailings paste body filling technology, namely adopts crude tailings lotion (or approximate lotion) bashing, does not add cementitious materials, rely on natural drainage of tailings deposition dehydrating, Non cemented filling technical operation is simple, with low cost, by many mining areas are favored.But often there is potential safety hazard in Non cemented filling, because natural subsidence dewatering time is longer, tailings water can not be discharged in time, obturation is made to be in High water cut state for a long time, fire dam bottom goaf can be caused to bear pressure larger, affect the stable of fire dam, personnel and device security are constituted a threat to, increase underground work risk.How being leached as early as possible by the gravity water in lotion or Paste-like body tailings slurry, make obturation reach stable, is a difficult problem of mine down-hole tailings Non cemented filling.
Domestic patent database also have some about mine goaf tailing fill dehydration technique open source literature report:
Such as: [application number] CN201210565190.2, [applying date] 2012.12.24, [title] one goaf group method for filling and treating on a large scale, its technical scheme is: divide filling unit, selects filler, arranges filling pipeline; Determine filling counterfort thickness according to calculating and carry out site operation, filling counterfort internal reservation drain hole and treatment hole, and hillock loaded filter of banking up after filling counterfort; Arrange filter pipe, and stretch out outside wall by the treatment hole of filling counterfort; At peak place construction filling borehole, diameter 133mm-150mm, as high-order tapping point, guarantees to connect top, the filling borehole of respective numbers of simultaneously should constructing according to actual conditions, carries out alternately filling.But this invention is not suitable for Non cemented filling, because a limited number of filter pipe does not reach the object of fast dewatering, the long dehydration phase, increase subsidence risk.
Such as: [application number] CN201420161397.8, [applying date] 2014.04.04, [title] tailing cemented filling dewatering and drainage device, disclose a kind of tailing cemented filling dewatering and drainage device, it comprises some gutters of filling partition wall and setting parallel to each other, and one end of gutter passes from filling partition wall; Each root gutter is connected with some filter pipes respectively by threeway; Described filter pipe trend is all vertical with gutter.Ensure that drainage pipeline and obturation can uniform contact, and contact area is comparatively large, ensure that obturation has good water permeability.Direct UNICOM bottom gutter and filter pipe, drainage better effects if.Same, some filter pipes of this utility model do not reach the object of fast dewatering yet, and bending, tediously long drainage channel very easily blocks.
Such as: [application number] CN201320446777.1, [applying date] 2013.07.25, [title] a kind of tailing-filled mould bag damming out device, this device comprises tailing-filled mould bag and builds a dam, tailing-filled mould bag is built a dam the multilayer film bag dam comprising and forming with tailing-filled geotechnical fabric bag, establishes flexible porous tube at upper surface interval, every layer of mould bag dam.Described flexible porous tube curves outsourcing one deck water permeability earth working material after helical form by elastomeric material.Tailing-filled mould bag built a dam in process by flexible porous tube and terminate to discharge in the timely ordered set of infiltration of rear mold bag dam body inside.It is to be filled in the geotechnical fabric bag that is laid on the dam foundation by Hydraulic transportation after utilizing tailings pulping and to form the novel damming method of one of dam body that described tailing-filled mould bag is built a dam.This utility model can play dehydration, but complex operation, and drainage efficiency is not high.
Therefore, it is low to there is dewatering efficiency in existing tailings filling dehydration technique, and the problem of easily blocking up, does not reach the object of fast dewatering, require further improvement.
