Description

Collapse structure is prevented to waste dump

Technical Field

The utility model relates to the field of gangue treatment, in particular to a gangue dump collapse prevention structure.

Background

The gangue hill is a place for intensively piling gangue in coal mines and coal preparation plants, and because the gangue hill is mostly formed by natural piling, the gangue hill has the characteristics of loose structure and poor stability, and is extremely easy to cause geological disasters in two aspects.

Firstly, because the gangue hill is internally self-burned for a long time, a large amount of heat energy is accumulated, and a large amount of rainwater is injected into a fire area when the storm is suddenly dropped, so that the internal height Wen Gandan is subjected to a physical-chemical reaction after meeting water: the high temperature causes a large amount of rainwater to become vapor, so that the internal pressure of the gangue hill is rapidly increased, and the internal temperature of the gangue hill is rapidly up to about 800 ℃, so that water is decomposed to form water gas, and the water gas is mixed with CO, H ₂ S and other gases to generate explosion, thereby causing the gangue hill to collapse and landslide.

Secondly, if the coal gangue is not accumulated stably enough, the structure is unreasonable, and under the impact of a large amount of rainwater in rainy season, the coal gangue debris flow is easy to occur.

At present, the main means for solving the problems of the collapse of the gangue dump, the landslide and the mud flow is to build a gangue blocking dam, and the aim of stabilizing the gangue dump and preventing the reburning is fulfilled by building a main gangue blocking dam on one side of the gangue dump, but the gangue blocking dam cannot provide support for the interior of the main body of the gangue dump because the drainage problem of the gangue dump cannot be effectively solved, so that the collapse of the gangue dump, the landslide and the mud flow cannot be effectively prevented.
