Gangue is the solid waste emission from coal mining and coal washing process. At present, Chinas annual emission of gangue is approximately 360million tons, coupled with the emission over the years, Chinas total stockpiles of coal gangue resource has reached 50 million tons. The piling up of gangue not only occupies large land, but also will pollute the surrounding soil and groundwater.
In recent years, coal gangue resources have gradually become the focus of the study on comprehensive utilization. Among them, the manufacturing construction material with gangue is one of the effective ways for gangue recycling. Instead of clay with gangue as brick-making raw materials can reduce the exploitation of fertile land. In addition, brick making can also make use of the combustibility of coal gangue for coal conservation.
In the process of brick making with coal gangue, improving the blank plastic is very important, which requires coal gangue appropriate fine crushing technology. Therefore, coal gangue resource is the important resource in the future.
