Description
Technical field
The present invention relates to a kind of red mud-based fluid swelling filling material used in stowing method mining, belong to (abbreviation " three times ") mining technique field under buildings, water body, railway.
Background technology
There are abundant Mineral resources in China, and reserves are at the forefront in the world.Above mineral reserve, there are buildings, water body and railway, the ，Ge mining area, super highway of One's name is legion all to exist to some extent " three times " to press the problem of Mineral resources.For a long time, China mine " three times " mining methods mainly adopt village (cities and towns) resettlement, band, pillars of a house exploitation and this several method of filling mining.
Wherein, according to compaction material and mode of movement, the filling in mine production technique mainly contains following several:
1, dry filling: be that the dry filling materials such as the piece stone of collection, sandstone, soil, industrial residue are transported to by manpower, gravity or mechanical means and treat fill area, form compressible loose pack body.The shortcomings such as such filling labour intensity is large, operating cost is high, the stope filling time is long, production efficiency is low, and filling effect is undesirable.
2, hydraulic stowing: be, by waterpower, mine tailing is filled with to worked-out section.Its weak point is: the compaction material of hydraulic stowing lacks cohesive characteristic, can not form the obturator of firm self-support, and stope needs a large amount of dehydrations.
3, consolidated fill: generally adopt silicate cement or other gelling material to add in low concentration of water sandfilling material, mass concentration 60%～68%, both improved strength of filling mass, is easy to again realize carrying.But this technique in use exist slip solidify slowly, emanate layering, intensity is low and the phenomenon such as inhomogeneous, but also has down-hole when dehydration gelling material and fine-grained tailing easily runs off, down-hole waste water, thin sludge-polluted environment, draining, spoil disposal expense are high, the problems such as the stope mining cycle is long, and production efficiency is low.
For the coal mining filling, general filling aggregate used is mainly the solid waste such as coal gangue, mine tailing, river sand, soil inferior, and fines is generally flyash, blast-furnace slag etc.Its not enough outstanding behaviours is 3 problems: 1. casting resin connects the top difficulty, and filling effect is poor.Due to lotion or Paste-like slurry poor fluidity, be difficult to guarantee that filling is even, especially slip solidifies rear drying shrinkage 30% left and right, is difficult to reach the purpose of controlling subsidence.2. carry cost high.The colliery resource is relative unlike metal ore concentrates on less scope, and the scope extended in plane is usually very large, and casting resin need to be grown distance and carries, and adopts lotion or the paste-like backfill of pumping mode certainly will increase filling cost.3. the broken cost of coal gangue increases filling cost.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of waste red mud, expansion filling active effective, that can solve goaf filling of can taking full advantage of to connect top and long apart from transportation problem and can control the red mud-based fluid swelling filling material of earth's surface distortion.
The present invention also aims to provide that a kind of expansion filling is effective, the making method simple red mud-based fluid swelling filling material of processing step.
The technical solution adopted for the present invention to solve the technical problems is: a kind of red mud-based fluid swelling filling material is characterized in that: by A, two kinds of components of B, formed, wherein:
The A component is comprised of by following proportioning following starting material:

3
Water 650～800kg/m
3
The B component is swelling agent, and its content is 0.3～0.5kg/m
3
During filling, the A component is mixed with the B component.
Described swelling agent is aluminium powder.While adding swelling agent, can regulate its addition according to the size of required rate of expansion, guarantee that the red mud-based fluid swelling filling material drawn rate of expansion is 10%～30%.
Described solidifying agent is one or more in cement, lime or terra alba.
The method for making of above-mentioned red mud-based fluid swelling filling material, comprise the steps:
(1) prepare the A component:
A, centrotheca are prefabricated: according to flyash and water weight ratio 1: 1.3～1.35, mixing and stirring is standby;
B, the preparation of A component: the water of centrotheca, red mud, solidifying agent and residual mass is inputted in steel basin continuously, and rapid strong is uniformly mixed;
(2) during filling, B component swelling agent is evenly added in the A component and gets final product.
The rate of expansion of the red mud-based fluid swelling filling material made according to said components and method can reach 10%～30%; this red mud-based fluid swelling filling material presetting period is 1.5～2 hours; 2 hours start to solidify; ultimate compression strength surpassed 2.5MPa in 7 days; can meet timely filling, fully connect the requirement of top, rapid solidification; band through the filling of this compaction material can effectively support superincumbent stratum, thereby reaches the purpose of controlling earth's surface distortion, protection above ground structure and dirt settling.
The waste residue of discharging when red mud is Aluminium industry extraction aluminum oxide, 1 ton of aluminum oxide of the every production of average, 1.0～2.0 tons of red muds of subsidiary generation, China is as the world the 4th large alumina producing state, the red mud of annual discharge is up to millions of tons, and a large amount of red muds can not fully effectively utilize, and can only rely on large-area stockyard to stack, taken a large amount of soils, also environment has been caused to serious pollution.In red mud, contain aluminum oxide and siliceous material etc., wherein aluminum oxide reacts with water and generates gas, in obturator, form bubble, produce and expand, siliceous material can form as obturator the silica compound that contains crystal water, can strengthen intensity and the water content of obturator, component using red mud as compaction material, can turn waste into wealth, waste is fully used, save the energy.
