Description
Technical field
Filling slurry the present invention relates to a kind of binder materials of filling in mine and containing the binder materials.
Background technology
Ardealite is the industry byproduct of phosphorous chemical industry enterprise Wet-process phosphoric acid (WPPA), and every 1 ton of phosphoric acid will produce about 5 tons of phosphorus stone
Cream.With the fast development of China's phosphorus chemical industry, annual by-product ardealite alreadys exceed 40,000,000 tons, adds up the phosphorus of accumulation
Gypsum is more than about 200,000,000 tons.Due to a variety of causes, China's ardealite resource utilization rate less than 15%, make by remaining part at present
To accumulate or fill for solid waste, this not only occupies substantial amounts of soil, and serious pollution is also caused to surrounding environment, because
This accelerates very urgent to the recycling of ardealite.
On the other hand, mining industry is while resource is asked for, and forms substantial amounts of goaf, the unstability in goaf collapse or
Avalanche, substantial amounts of soil and vegetation is wrecked, or even cause security incident.A large amount of CHARACTERISTICS OF TAILINGS SANDs caused by mining simultaneously,
Grain is superfine, and composition fluctuation is big, it is difficult to utilizes, these CHARACTERISTICS OF TAILINGS SANDs being not used are piled into mine tailing mountain, are not only the pole of resource
It is big to waste, and great pollution is caused to environment.It is to protect earth's surface not collapse with cut and fill mineral deposit, realizes
Mining industry and the most reliable technical support of harmonious development.And cheap mine waste CHARACTERISTICS OF TAILINGS SAND is widely used in mine
Filling, the raw material of filling in mine material is not only provided, the problem of also solving mine waste entrainment environment and occupy cultivated land,
With very great meaning.The filling cementing agent that current most of filling in mine mining codes use remains as portland cement,
It is also rare suitable for the special gelling agent of filling in mine feature.
Loess Plateau is the area that loess distribution is most on the earth, is affected by it, and loess is in China central and west regions
It is widely distributed, including the ground such as Qinghai, Shaanxi, Shanxi, the Inner Mongol, Henan, Hebei.Loess is considered as weathering more and precipitates to be formed, its
Formed age is later, and property is loose porous, and cohesive force is poor, and particle is thinner, the silty sand belonged in sandy soil.Loess has cheap easy
The characteristics of obtaining, using this natural resources advantage, using loess as auxiliary material, and is developed using ardealite and meets mine
The filler of goaf filling requirement, it is significant.
The content of the invention
Casting resin it is an object of the invention to provide a kind of binder materials of filling in mine and containing the binder materials
Slurry.
The technical solution used in the present invention is：
A kind of binder materials of filling in mine, is made up of the raw material of following mass parts：40~65 parts of ardealites, 18~25
Part loess, 10~22 parts of slags, 5~15 parts of slags, 0.1~0.8 part of water reducer.
The particle diameter of loess is less than 85 μm.
Slag is blast furnace slag.
Water reducer is lignin sulfonate water reducer, naphthalene water reducer, melamine system water reducer, sulfamate system
At least one of water reducer, fatty acid series water reducer, poly carboxylic acid series water reducer.
A kind of slurry of filling in mine, including the binder materials of above-mentioned filling in mine, cement and water.
In slurry, the mass ratio of binder materials and cement is 1：(3~8).
In slurry, cement is 42.5 or 42.5R type cement.
The water content of slurry is 30wt%~40wt%.
The beneficial effects of the invention are as follows：
The present invention is directed to the requirement of filling in mine gelling agent, has designed and developed out using ardealite as primary raw material, and be aided with
The filling in mine binder materials of loess.By the filling slurry that is prepared of binder materials of the present invention compared with current cement,
Its intensity is integrally better than used cement, while the filling slurry of the present invention fully meets the flowing required by filling in mine
Property.The filling slurry of the present invention can not only substitute cement, while also have completely due to having used loess to make filling cost lower
Beneficial to the ardealite of consumption bulk deposition, be advantageous to environmental protection.
