Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burial industrial waste composition, and more particularly to a burial industrial waste composition useful for preventing ground subsidence or the like at a site of a mining site.

[0002]

2. Description of the Related Art As a conventional method for treating industrial waste, the following method is generally used. First, there is a method in which industrial waste itself is transported by a dump truck or the like and dumped in an inland mountainous depression. Then, the surrounding soil is piled up on top of the industrial waste that has been landfilled to some extent for post-treatment.

A simple method is also employed in which a hole is dug up in a flat land, the industrial waste itself is simply dropped into the hole, and the dug soil is refilled. Further, in the place where mineral resources are produced, there is also adopted a method in which after open-pit mining of minerals, industrial wastes are collected, transported, dropped, and embanked on them.

Depending on the type of industrial waste, a method of storing it in a container such as an aluminum drum can, a method of landfilling the beach, a method of burning it in a combustion plant, a method of dumping it into the ocean, etc. are adopted. Has been done.

In these industrial waste treatment methods, the idea of secondary reuse of industrial waste is rarely seen, and the emphasis is placed solely on the efficiency of the final treatment of industrial waste. There is.

[0006] By the way, today's resource saving or reuse of resources is an important and urgent issue for the nation, and from the viewpoint of national land conservation and environmental protection, it is not limited to the manufacturing industry but to the general public. There is a strong demand for a safe and useful method for treating industrial waste.

The object of the present invention is to overcome the above-mentioned problems, and to improve the mechanical strength of the cured product of the composition while effectively utilizing the industrial waste, and to dig it. An object of the present invention is to provide an industrial waste composition for burying, which is useful for preventing ground subsidence of the site.

The industrial waste composition for burial of the present invention comprises industrial waste, mountain sand (mountain soil) and a curing agent.
It is characterized in that 5 to 30 parts by volume of mountain sand (mountain soil) and 10 to 55 parts by volume of the curing agent are used with respect to 00 parts by volume.

One embodiment of the industrial waste composition for burial of the present invention is 55 to 60% by volume of industrial waste and 5% cement.
-10% by volume, mountain soil (sand) 25-30% by volume and water 5
Examples include those consisting of 10 to 10% by volume.

In another embodiment, 80 to 90% by volume of industrial waste and 10 to 20% by volume of tar-based substances are included.
It is made of.

In the industrial waste composition for burial of the present invention, the mechanical strength of the cured product of the composition can be adjusted by adjusting the mixing ratio of the curing agent at the time of mixing.

The industrial waste used in the present invention may be any as long as it is generally called industrial waste. Examples of this industrial waste include empty bottles such as glass products; waste products such as roof tiles, baked goods, tiles, etc .; weeds such as kaya and bark used for roofs; rubber for old automobile tires, etc. Petroleum products such as vinyl, styrofoam, acrylic, vinyl chloride and their processed products (including asphalt for roads); pulp products such as paper, cardboard, pressboard products, baking materials, etc. Metals such as; sludge from sediments of waterworks and factories; ash after using boilers, soot from Entz, ash such as ash after incineration; timber such as plywood, plywood and construction waste; blocks, poles, construction waste Cement, etc .; Paints (water properties) and other coated products and chemicals; Dam sediments (earth) and other resource waste materials; Clothes and other waste material fibers. Among these, from the viewpoint of mechanical strength for burying of the present invention, glass, ash, baked products, tiles, rubber such as old automobile tires, vinyl, petroleum products such as Styrofoam, paper, pulp products such as cardboard. Use is preferred.

As the curing agent used in the present invention, any curing agent can be used so long as it can be solidified together with industrial waste. Examples of such curing agents include cement-based compositions and tar-based substances. Here, as a concrete example of the cement-based composition, 50 kg of plastic waste materials and 10 blocks waste materials are used.
0 kg, 100 kg glass waste, 50 kg old automobile tires,
An example of the material is 200 g of gypsum board waste material, 300 kg of mountain soil, 100 kg of hardener cement, and 10 to 20 kg of water. When a tar-based substance is used as the curing agent, 20 to 30 kg of tar and the above-mentioned waste material are used, and the same processing method as the method of heating and using as asphalt for paving can be mentioned. Among these curing agents, it is preferable to use cement-based compositions and tar-based substances from the viewpoint of mechanical strength for embedding in the present invention.

The composition ratio of the industrial waste composition for burial of the present invention is usually 10 to 55 relative to 100 parts by volume of industrial waste.
The capacity part. If the mixing ratio is less than 10 parts by volume, the earth pressure strength cannot be obtained, and if it exceeds 55 parts by volume, the unit cost is too high, which is not desirable. It is preferably 5 to 10 parts by volume.

The industrial waste composition for burial of the present invention can be used by crushing and mixing in large and small plants, stirring with a curing agent to cure, if necessary. The amount of the curing agent used can be adjusted depending on the pressure strength.

The burial industrial waste composition of the present invention can be easily manufactured by mixing the above-mentioned industrial waste and the curing agent in a predetermined ratio and applying a conventional mixing method. For example, industrial waste is crushed in a conventional crushing plant and screened to recycle useful materials while delivering combustibles to a combustion plant. The industrial waste after being subjected to the sorting machine and the hardening agent such as cement are mixed in a mixing plant by adding water and the like as necessary, and stirred to obtain the burial industrial waste composition of the present invention. Then, the obtained industrial waste composition for burial is pressure-fed to a discharge site by a pressure pump plant, discharged to the site, and left as it is to form a part of rock in an underground cavity. These series of steps can be more easily understood with reference to FIG. 1, which is a flow chart showing an example of the industrial waste composition for burial of the present invention.

The industrial waste composition for burial of the present invention is used, for example, for repairing underground cavities such as sites of underground mining sites where it is necessary to prevent land subsidence and underground depression in advance, road construction grounds and landfill sites. It is extremely useful because it can be used to repair underground cavities for re-mining of underground resources at the location where construction of underground works and materials for civil engineering works has been completed, and it has cost advantages. ..

A case where the industrial waste composition for burial of the present invention is applied to a site of a mining site will be described with reference to FIG. First, the industrial waste is crushed as much as possible in the crushing plant 1 and fed to the sorter 2 for separation. The fed industrial waste is agitated and mixed with a hardening agent such as cement in the mixing plant 3 to obtain the burial industrial waste composition of the present invention. This burial industrial waste composition is pressure-fed by the pressure pump plant 4, and is discharged at the discharge site in the underground cavity through the pressure supply hose 5 extending to the underground cavity in the site of the excavation site.
